## Question
How many deaths from Operation Epic Fury will the U.S. government officially report on August 31, 2026?
## Description / Resolution Criteria
## Description
New York Times: [Number of U.S. Troop Deaths Suddenly Appears Lower on Pentagon Website](https://www.nytimes.com/2026/07/23/us/politics/iran-troop-deaths.html?unlocked_article_code=1.0FA.86bj.L2y6WJv5Bcp5\&smid=url-share)
> On Wednesday, the Pentagon reported on its casualties website that a total of 18 American service members had been killed during the war in Iran.
> By Thursday, the Defense Department had lowered that number, reporting that 14 American troops had been killed in the war.
> Three military officials said that one reason behind the change was that the Trump administration decided to remove four service members killed this past weekend from the list — three in Jordan and one in northern Iraq — because their deaths occurred after President Trump declared a cease-fire in the war in April.
> Since the cease-fire collapsed, the Pentagon has provided little information about the American military strategy and has been slow to release information about troops’ injuries. The last major Pentagon briefing on the war was in early May.
> The Defense Department has said that disclosing Iranian strikes on bases where U.S. troops are housed would compromise operational security.
> The Pentagon withheld information about three Iranian strikes last week in Jordan that injured dozens of U.S. service members and damaged several helicopters, according to several U.S. officials, who spoke on the condition of anonymity to discuss operational matters.
> After an Iranian strike in Jordan on Friday killed three soldiers, the Pentagon’s chief spokesman, Sean Parnell, acknowledged that the number of U.S. military casualties since July 7 had risen to nearly 100.

## Resolution Criteria
This question resolves as the total number of U.S. military deaths from Operation Epic Fury reported by the U.S. government at its [Defense Casualty Analysis System](https://dcas.dmdc.osd.mil/dcas/conflictCasualties/oefu/byCategory) tracker as of August 31, 2026. 
## Fine Print
This question's information (resolution criteria, fine print, background info, etc) is synced with an [original identical question](https://www.metaculus.com/questions/44802) which opened on 2026-07-25 00:00:00. This question will resolve based on the resolution criteria and fine print of the linked original question. However, if this question would resolve differently than the original question, then this question will be annulled. Additionally, if the original question's resolution could have been known before this question opened, then this question will be annulled.
## Range
The answer must be a number in [9.5, 209.5] (units: total deaths).
## Sub-question decomposition (planner)
- (w=0.35) Will lethal hostilities involving U.S. forces in the Iran war (Operation Epic Fury) continue at a pace producing additional U.S. military deaths through August 31, 2026 (i.e., no durable cease-fire re-established before mid-August 2026)? — The dominant driver of how much the DCAS count grows between late July and Aug 31, 2026 is whether combat deaths keep ac
- (w=0.25) Will the DCAS/Pentagon official tally continue to lag or exclude some U.S. deaths reported by media (i.e., official count materially lower than press tallies as of Aug 31, 2026)? — The NYT story documents deliberate downward revision and exclusion of post-cease-fire deaths; DCAS is the resolution sou
- (w=0.25) Will the DCAS Operation Epic Fury total be greater than 40 deaths as of August 31, 2026? — Directly probes the upper tail — requires roughly a tripling from the ~14-18 baseline, implying sustained intense combat
- (w=0.15) Will the DCAS Operation Epic Fury total be 20 or fewer deaths as of August 31, 2026? — Probes the lower tail — cease-fire holds and/or continued official exclusions keep the number near the current 14-18 bas

Information gaps:
- No data on DCAS Epic Fury count after ~Aug 1, 2026 (one month of the resolution window unobserved)
- Unknown whether the 'Overseas Operations Casualties' category will be merged back into Epic Fury by Aug 31
- No base rate for how often DCAS reclassifies/reverses casualty categorizations under congressional or press pressure
- No U.S. fatality-rate data for August 2026 or status of cease-fire talks after July 29
Key uncertainties:
- Whether post-July-7 deaths are attributed to Epic Fury or a separate category
- Whether a durable cease-fire is re-established in August
- Possibility of a mass-casualty event (base strike, aircraft loss) adding many deaths at once
- Whether congressional/media pressure forces the Pentagon to restore removed deaths
## Required pre-forecast walkthrough
Before giving percentiles, address these explicitly in your rationale:
(a) The time left until the question resolves.
(b) The outcome if NOTHING changes from today (the status quo value).
(c) The outcome if the CURRENT TREND continues.
(d) The expectations of experts / markets / base rates.
(e) A plausible scenario that produces a LOW outcome (near p10).
(f) A plausible scenario that produces a HIGH outcome (near p90).
## Calibration guidance
- **Be humble about tails.** Good forecasters set WIDE 90/10 intervals to account for unknown unknowns. Narrow tails get punished by the log score far more than slightly-biased medians.
- **Status quo anchoring.** The p50 should be close to the status quo value unless you have strong evidence of a trend.
- Don't pile mass at one value — if you're tempted, widen the spread by 20-50%.
- **Anchor on markets/experts.** If liquid market prices, analyst forecasts, or community percentiles appear in the evidence, center your distribution on them and widen — don't override a liquid market without specific evidence it lacks.
- **Relative-return / spread questions ("how much will X's return exceed Y's").** A near-zero median is usually right, but size the TAILS to the more VOLATILE leg, not to a generic 2-3pp spread. Two broad equity indices (e.g. Nasdaq-100 vs S&P 500) do stay within roughly ±2-3pp over a two-week window. But when one leg is a commodity (crude oil, gold) or a single high-beta stock (e.g. Nvidia), the two-week realized spread regularly reaches ±10pp or more — crude-vs-equity spreads have hit ±18pp. In those cases set p10/p90 to at least ±10pp (±15pp or wider for oil) while keeping the median near the status-quo spread; the 2-3pp intuition applies only to index-vs-index.
- **Heavy-tailed one-off magnitudes (opening-weekend box office, product-launch or debut numbers).** Pre-event tracking for these routinely misses by ±40% or more, and results land both far above and far below the consensus. Do NOT treat the displayed [min, max] range as the plausible range or clamp p10/p90 to its edges: the outcome can fall outside the range in either direction (recent opening weekends resolved ~7% above a displayed ceiling in one case and roughly half the displayed floor in another). Set p10/p90 wide enough that a 2x-or-0.5x surprise versus your central estimate still lands inside the interval, and when concrete current tracking disagrees with historical/franchise base rates, weight the tracking.

Narrow tails get punished by the log score far more than slightly-biased medians.\n- **Status quo anchoring.** The p50 should be close to the status quo value unless you have strong evidence of a trend.\n- Don\u0027t pile mass at one value \u2014 if you\u0027re tempted, widen the spread by 20-50%.\n- **Anchor on markets/experts.** If liquid market prices, analyst forecasts, or community percentiles appear in the evidence, center your distribution on them and widen \u2014 don\u0027t override a liquid market without specific evidence it lacks.\n- **Relative-return / spread questions (\"how much will X\u0027s return exceed Y\u0027s\").** A near-zero median is usually right, but size the TAILS to the more VOLATILE leg, not to a generic 2-3pp spread. Two broad equity indices (e.g. Nasdaq-100 vs S\u0026P 500) do stay within roughly \u00b12-3pp over a two-week window. But when one leg is a commodity (crude oil, gold) or a single high-beta stock (e.g. Nvidia), the two-week realized spread regularly reaches \u00b110pp or more \u2014 crude-vs-equity spreads have hit \u00b118pp. In those cases set p10/p90 to at least \u00b110pp (\u00b115pp or wider for oil) while keeping the median near the status-quo spread; the 2-3pp intuition applies only to index-vs-index.\n- **Heavy-tailed one-off magnitudes (opening-weekend box office, product-launch or debut numbers).** Pre-event tracking for these routinely misses by \u00b140% or more, and results land both far above and far below the consensus. Do NOT treat the displayed [min, max] range as the plausible range or clamp p10/p90 to its edges: the outcome can fall outside the range in either direction (recent opening weekends resolved ~7% above a displayed ceiling in one case and roughly half the displayed floor in another). Set p10/p90 wide enough that a 2x-or-0.5x surprise versus your central estimate still lands inside the interval, and when concrete current tracking disagrees with historical/franchise base rates, weight the tracking.\n\n## Output\n\nReturn ONLY valid JSON, no markdown fences:\n\n{\n \"rationale\": \"\u003caddress (a) through (f) above, then state your distribution \u2014 6-10 sentences total\u003e\",\n \"p10\": \u003cnumber\u003e,\n \"p25\": \u003cnumber\u003e,\n \"p50\": \u003cnumber\u003e,\n \"p75\": \u003cnumber\u003e,\n \"p90\": \u003cnumber\u003e\n}\n\nPercentiles MUST be in non-decreasing order (p10 \u003c= p25 \u003c= p50 \u003c= p75 \u003c= p90).\n",

"rationale": "(a) About five weeks remain between the late-July information cutoff and the Aug 31, 2026 resolution date. (b) Status quo: DCAS lists 14 deaths under Operation Epic Fury after the Pentagon moved four July deaths into a separate \u0027Overseas Operations Casualties\u0027 bucket and attributed the Jordan deaths to Inherent Resolve; if nothing changes the question resolves at 14. (c) Current trend: the Epic Fury line rose only from 13 (Apr 8) to 14 (late July) \u2014 net +1 in 3.5 months \u2014 even as total war deaths reached 18, because of aggressive reclassification; extrapolating gives ~14-16 by Aug 31. (d) A Monte Carlo in the evidence set gives median 22 with P(\u003e40)\u22488%, but that model appears to under-weight the strong documented tendency of DCAS to shunt new deaths out of the Epic Fury category; I shade its median down while keeping a comparable right tail. (e) Low scenario (~p10): the diplomatic off-ramp CBS reported materializes in early August, hostilities pause, and the Pentagon keeps all post-July-7 deaths in the separate category \u2014 DCAS stays at 14 (a further downward revision is conceivable but unlikely). (f) High scenario (~p90): fighting escalates through August with repeated successful Iranian missile strikes on Muwaffaq Salti and Iraqi/Gulf bases, a mass-casualty event (base strike or aircraft loss), plus congressional/press pressure forcing the Pentagon to fold the \u0027Overseas Operations\u0027 deaths back into Epic Fury \u2014 pushing the tally into the 30s-50s. Net: I anchor the median just above the status quo at 16-17 to reflect a meaningful chance of some additions or partial reconsolidation, with a long right tail for escalation plus reclassification."

The last major Pentagon briefing on the war was in early May.\n\n\u003e The Defense Department has said that disclosing Iranian strikes on bases where U.S. troops are housed would compromise operational security.\n\n\u003e The Pentagon withheld information about three Iranian strikes last week in Jordan that injured dozens of U.S. service members and damaged several helicopters, according to several U.S. officials, who spoke on the condition of anonymity to discuss operational matters.\n\n\u003e After an Iranian strike in Jordan on Friday killed three soldiers, the Pentagon\u2019s chief spokesman, Sean Parnell, acknowledged that the number of U.S. military casualties since July 7 had risen to nearly 100.\n\n`{\"format\": \"metac_reveal_and_close_in_period\", \"info\": {\"post_id\": 44802, \"question_id\": 44949}}`\n\n## Resolution Criteria\nThis question resolves as the total number of U.S. military deaths from Operation Epic Fury reported by the U.S. government at its [Defense Casualty Analysis System](https://dcas.dmdc.osd.mil/dcas/conflictCasualties/oefu/byCategory) tracker as of August 31, 2026.\u0026#x20;\n\n## Fine Print\nThis question\u0027s information (resolution criteria, fine print, background info, etc) is synced with an [original identical question](https://www.metaculus.com/questions/44802) which opened on 2026-07-25 00:00:00.
