This was extraordinarily bad. Moss was still alive, but he appeared to have an unexploded grenade inside him, with enough power to kill everybody inside the Humvee, should it explode. Its tail, sticking out of a smoking wound, left no indication of how much explosive—if any— was left in the warhead or in its detonator. The round could have been a dud, or a warhead that failed to arm but that still could explode. Unexploded ordnance in Afghanistan, especially old Soviet technology or Chinese knockoffs, wasn’t known for its stability.
