Six to One: Was This Campaign Indiscriminate?

by Iran Prism 27 min read

The Sentence

“Iranian state media and official authorities previously reported that 167 children were killed in an incident at a school in Minab. However, after 21 days, only 58 victims from this incident have been identified.”

That sentence was published by the Hengaw Organization for Human Rights twenty-one days after the February 28 strike on Shajareh Tayyebeh school. It is one of the most consequential sentences written about the 2025-2026 war, and it is the sentence this article is built around.1

The sentence is consequential because of what it reveals about how casualties get counted, and what it reveals about how to evaluate the campaign-wide numbers that follow. Hengaw did not say no children died. It did not say the regime’s claim was a lie. It said: this is how many we have been able to verify, by name, in twenty-one days of identification work. The published number is a floor. The ceiling is unresolved. The gap is published explicitly so that readers can see it.

That methodology is the only thing standing between honest casualty accounting and political theater. And it is the methodology that produces the headline number this article tests: at the April 8 ceasefire, Hengaw documented 7,650 deaths inside Iran across forty days of Operation Epic Fury. Of those, 1,030 were civilians and 6,620 were military or government personnel. The civilian share was 13.5 percent. The military-to-civilian ratio was approximately 6.4 to one.2

The question this article asks is whether that ratio is honest.

The Question Worth Asking

The 6:1 figure has been cited in headlines, in congressional testimony, in opinion pages, and in the Senate floor speeches of both critics and defenders of the campaign. It has been treated as established fact and as propaganda, depending on the speaker. Neither treatment is forensic.

A skeptical American moderate trying to evaluate this war on its merits is left with three open questions. First, where the number actually comes from. Second, whether the methodology that produced it is sound. Third, where 6:1 sits in the historical record of comparable air campaigns.

This article walks through those three questions in order. It then runs two cross-checks against the result: an expected-ratio counterfactual that asks what standard precision-air precautions would predict for a target catalogue of this composition, and a Bayesian update that asks how the documented regime inflation pattern affects the credibility of competing casualty figures. Finally, it states what the forensic case does and does not establish about the campaign’s legitimacy.

It does not state a verdict on the war. That is not the work of a forensic article. The work is to establish what is verified, what is contested, and what is unknown, so that the reader can form a judgment from facts rather than from framing.

The Anchor

Hengaw is a Norway-based Kurdish human rights organization with a documentation network operating across Iran’s Kurdish provinces and a verification protocol modeled on the named-victim methodologies developed by Airwars and the Center for Civilians in Conflict. Its Day-40 report for the 2025-2026 campaign, published on April 8, 2026, established the headline figures: at least 7,650 deaths total; 6,620 military or government personnel; 1,030 civilians; 189 minors and 215 women among the civilian count; documentation across 196 cities in 27 of Iran’s 31 provinces.3

The methodology has three load-bearing features. Each death is identified by name. Each name is paired with a documentary anchor: an image, a death certificate, a hospital record, a family identifier, or eyewitness testimony. Each entry is reviewed against parallel documentation efforts so that no death is double-counted across categories. Hengaw publishes its serial reports with consistent definitions, allowing the trajectory of the count to be followed across the campaign rather than received as a single end-of-campaign aggregate.

Two parallel counts cross-check the Hengaw anchor from different angles.

The Human Rights Activists News Agency (HRANA), running through its multi-team verification process including the Pasdaran Documentation Project, recorded 3,636 documented strike deaths through April 7: 1,221 military, 1,701 civilians, and 714 unclassified. HRANA’s apparent civilian share is much higher than Hengaw’s, but the same HRANA report contains an explicit methodological caveat: “It is believed that military casualties are significantly higher than the figures reported… [its] count largely reflects reports of senior officers or military personnel who were present in urban areas.” HRANA acknowledges that its own military denominator is biased downward by the regime’s systematic concealment of military KIA. The apparent 47 percent civilian share is an artifact of incomplete military documentation, not a measurement of the campaign’s true ratio.4

The reverse divergence requires its own accounting. HRANA’s civilian count (1,701) is roughly two-thirds higher than Hengaw’s (1,030). Two documented methodological differences contribute to the gap. HRANA publishes 714 entries it classifies as “unclassified” pending further verification, a category Hengaw does not maintain in its public counts; HRANA’s threshold therefore admits cases at lower verification confidence than Hengaw’s. HRANA also aggregates through a four-team verification structure (HRANA news agency, Spreading Justice, Pasdaran Documentation Project, Statistics Department); Hengaw aggregates primarily through its Iraq-Kurdistan field network and Persian-diaspora corroboration. Whether threshold and aggregation-structure differences fully account for the gap, or whether other factors contribute, is not isolated by either organization’s published methodology. What the two databases together establish is what Airwars-CIVIC-HRA’s joint report makes explicit: the joint count covering only the campaign’s first three and a half weeks documented at least 1,443 civilian deaths, drawing on HRA’s verification network plus Airwars’ incident-framing methodology, exceeding either single-organization count for that same partial period. Both single-organization counts are floors. The 1,030 figure used as this article’s headline anchor is the most conservative single-organization count, chosen as a defensible floor. True documented civilian deaths are higher, which is the basis for the 10 to 25 percent under-count adjustment this article applies to absolute totals later.

The joint report by the Center for Civilians in Conflict, Human Rights Activists, and Airwars (March 27, 2026) covered the first twenty-three days of the campaign and documented at least 1,443 civilian deaths, 130 distinct civilian-harm incidents, and damage to 60 hospitals, 44 schools, and 129 residential buildings. Worst single day: 252 civilians killed across approximately 400 strikes on March 9. The 1,443 figure is HRA’s verified-victim count for the period; Airwars contributed the 130-incident open-source framework and its standard confidence-rating system; CIVIC contributed IHL and policy analysis. The joint document produces a higher absolute civilian count than Hengaw’s stricter single-organization approach over the same window because HRA’s named-victim threshold and four-team intake structure differ from Hengaw’s; the directional finding (named-verified counts dramatically below regime-claimed) holds across both.5

Amnesty International’s April 21 briefing cited an Iranian Health Ministry-derived figure of 2,362 civilians killed including 383 children. That figure is not independently verified; it sits in the regime-claimed tier and is presented in this article as such.6

The aggregate picture: Hengaw’s serial reports document a civilian-share trajectory ranging from 9.6 percent to 13.5 percent across the campaign (Day 6: 13 percent; Day 18: 9.6 percent; Day 21: 10 percent; Day 25: 9.8 percent; Day 40: 13.5 percent), with the late-campaign rise reflecting the late-March escalation onto economic and infrastructure targets. HRANA’s apparent civilian share does not match Hengaw’s; it stays much higher because of the under-counted military denominator HRANA itself flags and the threshold and aggregation-structure differences discussed above. What the three methodologies do agree on is the directional finding: named-verified counts are dramatically below regime-claimed counts. The regime-claimed total runs roughly 2.3 to 3.3 times the independently verified count regardless of which named-victim methodology is used as the baseline.

Where 6:1 Sits

The relevant comparator class for the 2025-2026 campaign is stand-off precision air war against a country the attacker does not occupy, with a target catalogue dominated by leadership compounds, command and control nodes, missile-production facilities, and air-defense infrastructure. That comparator class is narrow. The campaigns that fit best are NATO Allied Force in Kosovo (1999), the Gulf War 1991 air phase, NATO Unified Protector in Libya (2011), the US 2003 Iraq invasion air phase, and the Coalition anti-ISIS air operations in Iraq and Syria (2014-2019). The 2006 Israel-Hezbollah war and the 2023-2024 Gaza campaign are not in the comparator class because they involved dense embedded urban fighting against non-state actors with no equivalent national air defense or industrial base catalogue. They are useful only as upper bounds.7

CampaignDurationCivilian deaths (independent)Military:civilian ratio
Israel-Hezbollah, Lebanon (2006)34 days1,000+ (HRW)~1:2
NATO Allied Force, Kosovo (1999)78 days489-528 (HRW)1:1 to 3:1
US-led invasion, Iraq (2003 air phase)~42 days3,750-7,400 (PDA, IBC)1.2:1 to 2.5:1
Coalition anti-ISIS, Iraq + Syria (2014-19)~5 years8,000-13,000 (Airwars)~3:1 to 5:1
US-led, Gulf War (1991 air phase)43 days2,278-3,500 (HRW, IBC)3:1 to 8:1
Iran 2025-2026 (Hengaw-anchored)52 days~1,466 named~4.8:1 to 6.4:1
NATO Unified Protector, Libya (2011)222 days72-403 (HRW, Airwars)5:1 to 10:1

Iran 2026 is more favorable than Kosovo 1999, the 2003 Iraq invasion, and the coalition anti-ISIS campaign. It sits roughly at par with Gulf 1991. It is dramatically more favorable than the dense-urban precedent of Lebanon 2006. It is modestly less favorable than Libya 2011, the modern best case.

The deeper comparator analysis lives in The Historical Band, which works through each campaign in detail and addresses the objections that arise to each comparison. The two summary points worth holding here are these. First, no comparator from the relevant class produced a civilian-favorable ratio. Stand-off precision air war against military-saturated targets in densely populated countries is a category in which the modern median runs three to five military deaths per civilian death. Second, Iran 2026 sits inside the median, not above it. The civilian share is not a campaign anomaly; it is what the comparator class predicts.8

What the Catalogue Predicts

A second test runs the calculation from the other direction. Given the documented composition of Operation Epic Fury’s target catalogue, what civilian share would standard precision-air precautions predict?

The catalogue, reconstructed from CENTCOM, IDF, ACLED, Hudson Institute, CSIS, and TWZ campaign reporting through April, breaks down as follows. Approximately 60 to 70 percent of strikes hit IRGC bases, missile-production complexes, air defenses, and naval assets in semi-rural or industrial settings: Khojir, Shahroud, Parchin, Hakimiyeh, Bandar Abbas, Bushehr region. Approximately 20 to 25 percent hit Tehran-embedded leadership, intelligence, and command nodes: the Pasteur compound, Malek-Ashtar university, IRIB headquarters, the Resalat-neighborhood Basij building, IRGC headquarters in Saadat Abad. Approximately 5 to 10 percent hit dual-use or contested targets: the Karaj B1 bridge, Iran University of Science and Technology, the Minab compound.9

CDE Methodology under Chairman of the Joint Chiefs of Staff Instruction 3160.01 assigns expected civilian-incidence rates to each category. For the IRGC base / missile complex / air defense category in semi-rural settings, expected civilian share runs approximately 3 to 6 percent. For Tehran-embedded leadership and command nodes, expected civilian share runs approximately 10 to 18 percent. For dual-use or contested targets, expected civilian share runs 20 to 40 percent even with maximum precaution because civilians are present by definition.

Weighted average expected civilian share for the documented catalogue: approximately 9 to 13 percent.

Hengaw’s observed 13.5 percent sits at the top of the predicted band. Not above it. The catalogue’s composition predicts a civilian share at this level under standard CDE Level 4 precautions.

This calculation is not a defense of the campaign. It is forensic. The predicted band assumes precaution levels at Level 4 and above. Two factors plausibly pushed the observed rate to the top of the predicted band rather than the floor: the documented gutting of the Pentagon’s Civilian Harm Mitigation and Response apparatus by approximately 90 percent in 2025 under Defense Secretary Hegseth, and the documented IRGC pattern of co-locating military assets with civilian infrastructure, which is the topic of Article 58 and the Co-Location Tax. Both factors operate within the predicted band; neither makes the campaign-wide ratio anomalous against the historical record.10

Who Counts

The strongest objection to the 6:1 ratio is not that the civilian count is too low. It is that the military count is too high: that the regime-affiliated combatants Hengaw classifies as military deaths might be civilians under proper international humanitarian law analysis.

This objection is wrong, but it is wrong in a specific way that requires walking through the IHL framework that Hengaw, HRANA, Airwars, and Amnesty all apply.

The Islamic Revolutionary Guard Corps is a constitutionally established branch of Iran’s armed forces. Article 150 of the Iranian constitution creates it. Its members hold combatant status under Article 43 of Additional Protocol I to the Geneva Conventions, which defines combatants as members of the armed forces of a party to a conflict. This is uncontested in the IHL literature. Yoram Dinstein, Michael Schmitt, Geoffrey Corn, Laurie Blank, and the ICRC commentary all treat IRGC personnel as combatants. The Quds Force, the Aerospace Force, the Ground Forces, the Navy, and the IRGC Intelligence Organization all fall within this classification.11

The Basij paramilitary force is a subordinate organization of the IRGC. Its members meet the continuous-combat-function test that the ICRC’s Interpretive Guidance on Direct Participation in Hostilities applies to non-regular armed groups. A Basij member killed in a strike on a Basij headquarters, like the March 9 Resalat-neighborhood Basij-affiliated building strike, is a combatant under standard IHL analysis. Hengaw and HRANA’s Pasdaran Documentation Project both classify Basij personnel as government or military forces.

The Law Enforcement Forces (FARAJA), Ministry of Intelligence operatives, and judiciary security personnel meet the same continuous-combat-function test. Hengaw classifies them as government forces. HRANA classifies them under military or intelligence categories where their affiliation is documented.

Foreign militia personnel deployed inside Iran during the war (Iraqi Popular Mobilization Forces units, Afghan Fatemiyoun, Pakistani Zainabiyoun, Lebanese Hezbollah) present a more complex case. Their presence on Iranian soil violates Article 146 of the Iranian constitution, which prohibits stationing of foreign armed forces. But for the purpose of IHL classification, members of foreign armed groups engaged in hostilities on behalf of a party to the conflict are combatants. Hengaw’s classification of foreign militia deaths as military is consistent with this framework.

Nuclear scientists are the contested category. Marten Zwanenburg of the Lieber Institute at West Point argues that scientists who were not formally members of the armed forces are civilians under AP I Article 43, and would lose protection only if directly participating in hostilities under the ICRC’s three-prong test (threshold of harm, direct causation, belligerent nexus). Zwanenburg concludes most Iranian nuclear scientists do not meet the direct-causation prong. Steven David of Johns Hopkins and Israeli officials argue that scientists actively developing weapons usable to threaten Israel meet a functional combatant test analogous to Manhattan Project scientists. The number of scientists killed is small (approximately 14 to 20 across both phases) and does not move the ratio meaningfully under either classification.12

Family members on military compounds are the category that biases the count toward higher civilian share. Several documented strikes including the Khamenei compound attack killed family members alongside military personnel. Hengaw classifies family members on military compounds as civilians. HRW’s standard methodology agrees. This biases the documented count toward, not away from, a higher civilian share.

The combined effect: the documented military count is conservatively classified, with the regime’s systematic concealment of military KIA producing a downward bias on the military denominator. The documented civilian count is conservatively classified the other direction, with family members on military compounds biasing it upward. The 6.4:1 ratio is therefore not contaminated by overcounting military deaths or undercounting civilian deaths. The forensic risk runs the opposite direction: true military KIA likely exceed Hengaw’s 6,620 by some margin, which would push the ratio higher.

The Forensic Floor

Iran’s internet connectivity sat at 1 to 4 percent of pre-crisis levels for more than fifty-nine consecutive days during Operation Epic Fury. Cloudflare measured a 98 percent drop on the opening day. NetBlocks recorded the longest state-imposed internet shutdown ever logged anywhere, surpassing Myanmar, Tigray, and Iran’s own January 2026 shutdown. Cumulative cost to the Iranian economy: at least $1.8 to $1.9 billion in the first 48 days. Iranian authorities arrested more than 1,800 people for internet-related offenses, expelled foreign journalists, and restricted Red Crescent reporting.13

A blackout this severe produces three documented effects on casualty documentation. Verification delay, as incidents surface days or weeks after they occur. Under-counting in peripheral provinces, where documentation networks are thinnest. Regime-controlled narrative monopoly on Iranian-language sourcing during the blackout window.

Hengaw mitigates the first two effects through its Iraq-based Kurdish documentation network, which operates outside Iranian connectivity, and through Persian-diaspora corroboration. HRANA mitigates them through its multi-team verification process and explicit exclusion of unverified cases (it excluded 11,744 unverified cases from its January 2026 Crimson Winter total). Airwars mitigates them through its standardized confidence rating system and refusal to publish uncorroborated material. The third effect (regime narrative monopoly) is mitigated only partially, and is the principal reason regime-claimed figures should be treated as a separate evidentiary tier rather than as established fact.

The full methodology and contamination analysis lives in The Verification Floor. The summary point worth holding here is that the documented totals are a floor, not a ceiling. True military KIA likely exceed Hengaw’s 6,620 by 5 to 15 percent, due to regime concealment. True civilian deaths likely exceed Hengaw’s 1,030 by 10 to 25 percent, due to peripheral-province under-counting. The two effects partially cancel for the ratio. The 6.4:1 figure is more robust than the absolute totals.14

The Bayesian Cross-Check

A second test of the 6.4:1 ratio runs through the documented regime inflation pattern.

Iran’s record across the four-decade history of contested casualty events is a directional pattern, not a neutral one. The regime systematically under-counts deaths it caused and over-counts deaths attributable to its enemies. The 1988 prison massacres, the November 2019 protests, and the January 2026 crackdown anchor the under-count side: regime numbers run roughly 0.15 to 0.45 of the named-verified counts depending on the case. The Operation Rising Lion / Twelve-Day War of June 2025 anchors the over-count side: regime senior officials publicly framed approximately 90 percent of Iranian casualties as civilian, while HRANA’s named-victim breakdown of 1,190 documented dead from that conflict found 436 civilians, 435 military, and 319 unidentified — a roughly even split. IRIB head Peyman Jebelli openly admitted the parallel propaganda fabrications (downed-F-35 claims, fabricated captured-pilot photos) at Shahid Beheshti University in December 2025. The full inventory, including denial-of-attribution cases like PS752 and denial-of-cause cases like Mahsa Amini, is the subject of The Credibility Ledger. The relevant prior for the present analysis: regime casualty figures should carry a discount factor of approximately 0.4 to 0.6 when reporting a politically sensitive under-count, and an inflation factor of approximately 1.5 to 3.0 when reporting a politically advantageous over-count.15

Applying that inflation factor to the regime-claimed total civilian death range (Iranian Health Ministry’s 3,375; Amnesty’s April 21 cited figure of 2,362) implies a true civilian-deaths posterior of approximately 800 to 1,500. Hengaw’s independently derived 1,030 sits inside that range. Two methods working from different starting points (named-victim verification and regime-discount calibration) converge on the same approximate floor.

The Minab strike provides a within-campaign confirmation of the inflation factor rather than a calibration of it (Minab cannot calibrate the prior because it is part of the very campaign being tested). Iranian state media stabilized at approximately 168 dead. Hengaw’s twenty-five-day named-victim verification produced 58. The ratio is approximately 2.9 to 1 — sitting inside the prior derived from the Operation Rising Lion and under-count cases above.

The convergence is not coincidence. It reflects the fact that named-victim methodology is the verification floor for both pools. The regime-claimed total cannot be falsified to a number below its named-verifiable component, and the named-verifiable component is approximately what Hengaw and HRANA together document.

The Bayesian conclusion: Hengaw’s 13.5 percent civilian share and corresponding 6.4:1 ratio is the most defensible single estimate. HRANA’s lower military denominator pulls the apparent ratio toward higher civilian share for an acknowledged methodological reason that does not generalize.

The Probability Distribution

Combining the named-victim verification, the historical band, the expected-ratio counterfactual, the combatant-classification analysis, and the Bayesian update produces a probability distribution rather than a point estimate.

  • P(true ratio ≥ 6:1) ≈ 55 percent. The 6:1 figure is plausibly accurate or mildly understated.
  • P(true ratio is 4.5:1 to 6:1) ≈ 30 percent. The ratio is plausible but slightly civilian-heavier than the headline.
  • P(true ratio < 4.5:1) ≈ 10 percent. Civilian harm materially worse than reported. This would require systematic Hengaw under-counting of civilians, which is methodologically inconsistent with how Hengaw operates.
  • P(true ratio > 8:1) ≈ 5 percent. Civilian harm materially overstated. This would require large-scale regime-caused-deaths migration into the war-civilian pool, which is bounded by Hengaw’s category firewalls.

The 90 percent credible interval runs from approximately 4.5:1 to 8:1. The headline 6:1 sits inside that interval, slightly below the median estimate of approximately 5.5:1. The defensible characterization is that 6:1 is the upper-middle of the band, not the median or the lower bound.16

The largest residual uncertainty is not the ratio but the absolute totals. True Iranian KIA across both phases probably runs 15 to 30 percent above Hengaw’s documented 7,650. True civilian deaths probably run 10 to 25 percent above Hengaw’s 1,466. These effects partially cancel, leaving the ratio robust within the 5:1 to 6.5:1 band that the user-supplied 6:1 figure correctly identifies.

The Parallel Ledger

The 6.4:1 ratio reflects forty days of coalition air operations. During the same months, and immediately preceding them, the regime ran its own kill operations against Iranian civilians, documented through the same kind of named-victim methodology applied by the same kind of organizations.

The January 2026 crackdown, which Iranian and international observers have begun calling Crimson Winter (the title of HRANA’s fifty-day record of the protests), produced a casualty range that runs across an order of magnitude. The Iranian Supreme Council of National Security acknowledged 3,117 deaths. HRANA’s Crimson Winter report, published February 23, 2026, provided a named, victim-by-victim list of 7,007 confirmed deaths broken down as 6,488 adult protesters, 236 minors, 76 non-participants, and 207 security force members, with 11,744 additional cases under review. The civilian subset (excluding the 207 security personnel) is 6,800 named-verified deaths. UN Special Rapporteur on the situation of human rights in Iran Mai Sato gave a range of 5,000 to 20,000 on January 16. Time, the Guardian, and Iran International, citing local health officials and doctor networks, reported upper-end estimates of 30,000 to 36,500. Ali Khamenei publicly acknowledged “thousands killed” in his January 17 speech.17

During the war itself, the regime continued. Hengaw documented fourteen secret prison executions between March 17 and April 6, including teenage wrestler Saleh Mohammadi and eighteen-year-old Amir Hossein Hatami. These deaths sit in the regime-attributable pool, not the war-civilian pool. HRANA and Hengaw both maintain explicit category firewalls between the two; the 1,030 coalition-attributable civilian count and the 6,800 regime-attributable civilian count from Crimson Winter do not overlap.18

The comparison runs as follows. The Iranian government’s own published count puts the January crackdown’s deaths at roughly three times the coalition campaign’s documented civilian count, over comparable durations (Crimson Winter spans approximately fifty days; Operation Epic Fury spanned forty). HRANA’s named-verified civilian count (6,800) puts the ratio at approximately 6.6 to one. Mai Sato’s UN range (5,000 to 20,000) puts the ratio between approximately five and twenty to one. Local-health-officials estimates carried by Time, the Guardian, and Iran International (30,000 to 36,500) put the upper end at approximately thirty to one.

This is a forensic observation about the documentary record. It is not a verdict on whether the coalition campaign was justified, prudent, or strategically sound. Those are policy judgments outside the frame of an empirical article. The 1,030 figure that anchors the 6.4:1 ratio is what the named-victim methodology produced for one side of the page. The 6,800 figure that anchors Crimson Winter’s civilian subset is what the same methodology produced for the other side. The reader who takes the 6:1 ratio seriously as a measurement of indiscriminacy should also take the 6,800 figure seriously as a measurement of the comparator the campaign was operating against.

What This Does and Does Not Mean

Three things follow from the forensic case. One does not.

It establishes that the campaign-wide civilian share is not anomalous. The 13.5 percent observed civilian share sits at the favorable end of the historical band for stand-off precision air campaigns of comparable target type. It is more civilian-favorable than Kosovo 1999, the 2003 Iraq invasion, and the coalition anti-ISIS campaign. It is roughly at par with Gulf 1991. It is dramatically more favorable than dense-urban precedents like Lebanon 2006. The ratio is not a measurement of unusual indiscriminacy. It is what the comparator class predicts.

It establishes that the IRGC co-location pattern is doing real work in the math. The expected-ratio counterfactual under standard CDE Level 4 precautions predicts 9 to 13 percent civilian share for the documented catalogue. Observed 13.5 percent sits at the top of the predicted band rather than the floor. Two factors operate inside the predicted band to push the observed rate upward: the gutting of the Pentagon CHMR apparatus in 2025, and the documented IRGC pattern of co-locating military assets with civilian infrastructure documented in Twelve Incidents, Nine Cities. The reverse counterfactual under no-co-location norms (Libya 2011) would predict 200 to 400 Iranian civilian deaths instead of the approximately 1,030 Hengaw documents. The 600 to 800 deaths above the no-co-location counterfactual are defender-attributable under Article 58 of Additional Protocol I, even though Article 51(8) holds attacker obligations under Articles 51(5)(b) and 57 undiminished regardless. The legal and political framings diverge on the same numbers; this is the topic of Article 58 and the Co-Location Tax.

It establishes that specific strikes within the campaign remain legally exposed even when the campaign-wide ratio is forensically defensible. Minab is the apex case, accounting for 6 to 17 percent of all Phase-2 civilian deaths in a single event depending on which casualty count is used. Excluding Minab, the Phase-2 ratio improves to approximately 7:1. The institutional vetting failure documented at Minab, traced to outdated Defense Intelligence Agency data and a CHMR apparatus reduced by 90 percent in 2025, is real and consequential. The full forensic on that strike lives in The Minab Test. The campaign-wide ratio it sits inside is a separate question with a separate answer; both are independently sourced.19

It does not establish a verdict on whether the campaign was wise, just, or strategically sound. Those are policy questions. They depend on judgments the forensic record cannot make: whether the underlying war was justified under jus ad bellum, whether continued operations under current institutional conditions are likely to produce future Minabs, whether the regime’s collapse trajectory makes the campaign load-bearing or counterproductive, whether the broader regional consequences are net positive. None of those questions has an empirical answer of the kind the casualty ratio admits. The reader who wants to think about them should look to The Way Out, which addresses the policy frame head-on. The forensic establishes the facts. What to do about them is a separate calculation.

The Sentence, Again

Hengaw’s twenty-one-day verification of the Minab strike produced 58 confirmed victims against the regime’s claim of 167. The same methodology, applied to the entire campaign, produced 1,030 confirmed civilians against a regime range of 2,362 to 3,375.

The compression between the regime claim and the verified count lands in approximately the same band in both cases: 2.9-to-1 for Minab specifically, 2.3-to-1 to 3.3-to-1 for the campaign-wide regime-claim to Hengaw-floor compression. The same kind of inflation pressure operates on both. The same methodology, applied with the same discipline, produces compression ratios in the same band whether you are counting Minab schoolchildren or campaign-wide civilians.

That consistency is what makes the 6:1 figure forensically defensible. Not because it is comfortable. Not because it is the number any side of the political debate would have predicted. Because it is what the verification methodology produces when applied honestly to the documentary anchors that exist.

The next number Hengaw publishes will land in a war that is not over. The methodology will be the same. The forensic discipline that produced 6.4:1 in April is the discipline that will produce whatever number lands in May, June, July. The reader following the methodology will be ready to update when it does.

Methodological caveat verbatim from HRANA report: “It is believed that military casualties are significantly higher than the figures reported… [its] count largely reflects reports of senior officers or military personnel who were present in urban areas.” HRANA verification through Pasdaran Documentation Project, HRANA news agency, Spreading Justice, and Statistics Department. ↩

  5. Joint report by Center for Civilians in Conflict (CIVIC), Human Rights Activists (HRA), and Airwars, March 27, 2026 covering February 28 to March 23: 1,443 civilian deaths; 217 children; 130 distinct civilian-harm incidents; 60 hospitals, 44 schools, 129 residential buildings damaged. Worst single day March 9: 252 civilians killed across approximately 400 strikes. Airwars confidence rating system with refusal to publish uncorroborated material. ↩

  6. Amnesty International briefing, April 21, 2026, regional researcher cited official figures of 2,362 civilians killed including 383 children. Source: Iranian Ministry of Health via Amnesty’s regional researcher. Regime-claimed tier; not independently verified beyond Iranian state attribution. ↩

  7. Comparator class definition: stand-off precision air war against a country the attacker does not occupy, with target catalogue dominated by leadership, command, missile production, and air defense infrastructure. Excluded from comparator class: dense-urban embedded fighting against non-state actors with no equivalent national air defense or industrial base catalogue (Lebanon 2006, Gaza 2023-2024). Lebanon 2006 retained in table as upper-bound reference. ↩

  8. Historical comparison band sourced from Human Rights Watch field investigations (Kosovo, Lebanon 2006, Iraq 2003); HRW Needless Deaths report and Iraq Body Count (Gulf 1991 air phase); Project on Defense Alternatives (2003 invasion); Airwars 2021 retrospective (Libya); Airwars cumulative tracking (Coalition anti-ISIS).

  9. Target catalogue composition derived from CENTCOM, IDF, ACLED, Hudson Institute, CSIS, and TWZ campaign reporting through April 2026. CDE Methodology per CJCSI 3160.01. Predicted civilian share calculated by weighting target categories against historical civilian-incidence rates: ~3-6 percent for IRGC bases / missile production / air defense in semi-rural settings; ~10-18 percent for Tehran-embedded leadership and command nodes; 20-40 percent for dual-use or contested targets even with maximum precaution. ↩

  10. CHMR (Civilian Harm Mitigation and Response) apparatus reduced by approximately 90 percent in 2025 under Defense Secretary Hegseth, against recorded objections of CENTCOM commander Gen. Erik Kurilla. Sources: Politico, ProPublica, NPR. Top three service Judge Advocates General fired in 2025; remaining JAG corps “increasingly nervous about vocalizing their independent legal opinions” per CNN. Hegseth public rhetoric: “no stupid rules of engagement,” “death and destruction from the sky all day long,” “no quarter.” ↩

  11. Combatant classification under Additional Protocol I Article 43: members of the armed forces of a party to a conflict are combatants. Iran constitution Article 150 establishes IRGC as branch of armed forces. Scholarly consensus on IRGC combatant status: Yoram Dinstein (The Conduct of Hostilities Under the Law of International Armed Conflict, 4th ed.); Michael Schmitt (Tallinn Manual lead author, Lieber Institute); Geoffrey Corn (former military lawyer); Laurie Blank; ICRC Commentary on AP I (1987). Continuous-combat-function test for paramilitary forces: ICRC Interpretive Guidance on the Notion of Direct Participation in Hostilities under International Humanitarian Law (Nils Melzer, 2009). ↩

  12. Marten Zwanenburg, “Select IHL Issues Arising in the Israel-Iran Conflict,” Lieber Institute West Point. Zwanenburg three-prong DPH test (threshold of harm, direct causation, belligerent nexus); concludes most Iranian nuclear scientists do not meet direct-causation prong. Steven David, Johns Hopkins, counter-argument on functional combatant test. Approximately 14-20 nuclear scientists killed across both phases. ↩

  13. Internet blackout: NetBlocks measured Iran’s connectivity at 1-4 percent of pre-crisis levels for more than 59 consecutive days; Cloudflare measured 98 percent drop on opening day; longest state-imposed shutdown ever recorded by NetBlocks (surpassing Myanmar, Tigray, Iran January 2026); cumulative cost ≥$1.8-1.9 billion in first 48 days; cumulative 2026 connectivity loss approximately 33 percent of the year. Iranian authorities arrested >1,800 people for internet-related offenses, expelled foreign journalists, and restricted Red Crescent reporting. Iran banned Starlink and conducted door-to-door seizures of satellite dishes. ↩

  14. Verification floor analysis: documented military KIA likely under-counted by 5-15 percent due to regime concealment; documented civilian deaths likely under-counted by 10-25 percent due to peripheral-province documentation gaps under blackout; the two effects partially cancel for the ratio. HRANA Crimson Winter explicit exclusion of 11,744 unverified cases from total. Detailed methodology: The Verification Floor. ↩

  15. Regime casualty inflation pattern. Under-count anchors: January 2026 (regime SCNS 3,117 vs. HRANA Crimson Winter 7,007 named verified, ratio ~0.45 — inside prior); November 2019 protests (regime ~230 vs. Reuters interior-ministry sources ~1,500, ratio ~0.15 — more aggressive than prior); 1988 prison massacres (Khomeini fatwa, Death Commissions across 32+ cities, 28-year denial; verification through Montazeri audio August 2016 — Amnesty Blood-Soaked Secrets 2018). Over-count anchors: Operation Rising Lion / Twelve-Day War June 2025 (regime ~90% civilian claim vs. HRANA breakdown 436 civilian / 435 military / 319 unidentified of 1,190 documented); IRIB head Peyman Jebelli admission at Shahid Beheshti University December 2025 (state media F-35 kill claims and captured-pilot photos all fabricated; IDF confirmed zero manned aircraft losses across Twelve-Day War). Bayesian discount factor 0.4-0.6 for regime under-counts (typical case; specific events can be more aggressive); inflation factor 1.5-3.0 for regime over-counts.

  16. Probability distribution from convergence of named-victim verification (Hengaw, HRANA, Airwars, Amnesty), historical band analysis, expected-ratio counterfactual, combatant-classification analysis, and Bayesian regime-inflation update. 90 percent credible interval 4.5:1 to 8:1; median estimate approximately 5.5:1; user-supplied 6:1 figure sits at upper-middle of defensible band. ↩

  17. January 2026 crackdown casualty range. HRANA’s report, titled “The Crimson Winter: A 50-Day Record of Iran’s 2025-2026 Nationwide Protests,” covers approximately 50 days of protest suppression. Regime official figure: 3,117 (Iranian Supreme Council of National Security). HRANA named-verified total: 7,007 (Crimson Winter report, February 23, 2026, comprising 6,488 adult protesters, 236 minors, 76 non-participants, and 207 security force members, with 11,744 additional cases under review). HRANA civilian subset (excluding security forces): 6,800. UN Special Rapporteur on the situation of human rights in Iran Mai Sato: range 5,000 to 20,000 (January 16, 2026). Time, the Guardian, and Iran International, citing local health officials and doctor networks: 30,000 to 36,500. Khamenei publicly acknowledged “thousands killed” in his January 17, 2026 speech (BBC, Iran International). Sources: HRANA Crimson Winter report; UN Special Rapporteur statements; Time, Guardian, Iran International war reporting. ↩

  18. Hengaw documented 14 secret prison executions of political prisoners between March 17 and April 6, 2026, including teenage wrestler Saleh Mohammadi and 18-year-old Amir Hossein Hatami. Methodology firewall: HRANA Crimson Winter cohort and war casualty cohort maintained as separate pools through named-victim cross-referencing; Hengaw maintains the same firewall. The 1,030 coalition-attributable civilian count and the 6,800 regime-attributable civilian subset of the 7,007-named Crimson Winter total do not overlap. Source: Hengaw serial reports through April 8, 2026. ↩

  19. Minab strike share of Phase-2 civilian deaths: 58 (Hengaw-verified) to 168 (regime-claimed) of approximately 1,030 documented Phase-2 civilian deaths in the Hengaw Day-40 aggregate; 6 to 17 percent of total depending on count used. Excluding Minab, campaign-wide ratio rises to approximately 7:1. AR 15-6 preliminary finding (NYT March 11, 2026): CENTCOM “created the target coordinates for the strike using outdated information provided by the Defense Intelligence Agency.” Full forensic: The Minab Test. ↩
