This is an issue before the ER or even stabilization point. You have a battlefield spread out over miles, with dead and wounded all over, and limited resources to pickup the wounded. This is about triage prior to sending people out of a bunker into an active combat zone to rescue wounded, not waste time on bodies or people that are going to die before they get to the ER.
