A simplified triage system shows promise for prioritizing trauma care in combat settings, but surgeons must be aware of its overtriage rate.

• Undertriage for major trauma (ISS ≥16) was just 3.6% with a sensitivity of 96.4%.
• Overall undertriage was 8.5% for all injuries with an AIS score of 3 or greater, with a sensitivity of 91.5%.

Surgeons should consider the trade-off, as overtriage reached 62.7%, indicating potential resource strain.

• Identifying subtle injuries remains challenging, underscoring the need for constant evaluation of triage protocols.
