Umm well I was under the impression that the survivors were protected in underground bunkers of some kind, and so they're not going to be any old idiots. SO they're not going to be a small group of rag-tag soldiers, they're gonna be some really, really rich people/ important government-type people. I was thinking the style of the group to be something along the lines of the Brotherhood of Steel from the Fallout games, like military/government people with cutting edge technology and good equipment, who come up and gather up any remaining survivors. From what I've heard, I'm not sure anyone outside of a bunker would have survived, so perhaps it is just a bunch of people who got a tad paranoid when they saw massed clouds of death raining down on them and ran for an abandoned nuke shelter of some kind. But then, who would fly the jet planes? And research obscure alien technology? Can YOU fly a jet fighter, intercept a far superior UFO and survive without hitting the side of a mountain? Unfortunately, I'm not very original when I try to think of names so all I can think of right now is 'The Enclave', 'The Improbable Mission Facility' or 'Phoenix Force'.
