|----|------|----------|
| B1 | Military Times — 7 US service members killed by enemy fire (KIA) in Operation Epic Fury (sourced from Pentagon DCAS data) | Yes |
| B2 | Military Times — 13 total US service members killed in Operation Epic Fury (sourced from CENTCOM) | Yes |
| B3 | HeyJackass.com — 2026 YTD Chicago shot & killed totals (sourced from CPD/CFD/ME data) | Yes |
| B4 | NBC Chicago — Chicago murders up 16% in March 2026, 32 shootings in one week (sourced from CPD crime statistics) | Yes |

## Proof Logic

The claim compares two quantities: Americans killed in Chicago shootings during a four-week window in March 2026, and US service members killed in action (KIA) in the Iran war through April 18, 2026.

**US military casualties:** According to the Pentagon's Defense Casualty Analysis System (DCAS), 7 US service members were killed by enemy fire (KIA) during Operation Epic Fury (B1). An additional 6 Air Force personnel died in a KC-135 refueling aircraft accident classified as "non-hostile," bringing the total to 13 (B2). A ceasefire took effect on April 8, 2026, with no additional KIA reported since.

**Chicago shooting deaths:** Chicago recorded 41 homicides in March 2026, as reported by CPD data covered by WTTW, NBC Chicago (B4), and corroborated by HeyJackass.com (B3). Of all 2026 Chicago homicides, approximately 90.3% were from gunshot wounds (112 of 124 total homicides year-to-date per B3). Applying this conservative rate to March's 41 homicides yields approximately 37 shooting deaths for the full 31-day month. A four-week (28-day) window contains at minimum 28/31 of the monthly total, giving a floor of approximately 33 shooting deaths.

This estimate is corroborated by CBS Chicago's weekend shooting reports, which document at least 12 people killed in shooting incidents across just three weekends — Feb 27-Mar 2 (5 killed, B7), Mar 13-16 (3 killed, B6), and Mar 20-23 (4 killed, B5). That 12 deaths occurred in only 9 days of weekend coverage supports the monthly rate of ~37 shooting deaths.

**Comparison:** The minimum conservative estimate of Chicago shooting deaths in any four-week window in March 2026 (~33) exceeds the US KIA count (7) by a factor of nearly 5×. Even under the broadest possible interpretation — comparing against all 13 US military deaths (including 6 non-hostile) — Chicago's four-week shooting death toll (~33) still exceeds the war casualties by more than 2.5×.

## What could challenge this verdict?

Four adversarial scenarios were investigated:

**Unreported KIA:** A ceasefire took effect April 8, 2026. No additional US KIA have been reported. The Intercept raised concerns about undercounting of wounded service members, but the killed count (7 KIA / 13 total) has not been disputed. Even substantial undercounting could not close the 26+ margin.

**KIA definition:** "Killed in action" specifically means killed by enemy fire. The 6 KC-135 crew deaths were classified as "non-hostile" by the Pentagon. However, even using all 13 deaths, the claim still holds (33 > 13).

**Inflated Chicago count:** The proof uses only fatal shooting victims ("shot & killed"), not total shooting victims (which includes non-fatal injuries). The 137 total shooting victims reported by CPD is not used in the comparison.

**March homicide accuracy:** Multiple independent outlets confirm 41 March homicides from CPD data. The 16% year-over-year increase (from 35 in March 2025) is consistently reported.

## Conclusion

**PROVED.** At minimum ~33 people were killed in Chicago shootings during any four-week period in March 2026, compared to 7 US service members killed in action (KIA) in the Iran war through April 18, 2026. The claim holds by a wide margin under any reasonable interpretation — including the broadest reading that counts all 13 US military deaths against a conservative estimate of Chicago shooting fatalities. All 7 citations were independently verified against their source pages.
