So, two raiders are talking smack to each other. One's head suddenly explodes from the impact of a 308 round. His friend doesn't react. Really? There could be a perception and/or intelligence based reaction time so that, if the PC is quick enough, a couple raiders or a few muties can be sniped before their buddies start running around, taking cover, looking for the PC, etc. It would be really cool if npcs, muties, and creatures also reacted to finding their friends' corpses, making the grab function useful for hiding bodies.
