The Predators use a combined high res video for day and FLIR together. It's very hard to hide your heat, almost impossible. It can only be done in earth bunkers etc, a poncho or blanket ro pretend you are a rock (which the Afghans used against Soviet helos) won't help.
The Predators of course need intell to know where to look and who to look for, but they don't need anyone to lase a target. They have their own on board. It's all done via sat data link remotely.
Like you said, it's going to be tough to be a guerrilla in the old sense any more. The only camouflage which will work will be UPS brown or gray pinstripes etc.
Visualize vehicles that are the land-equivalent of carriers, launching small armed drones and controling them from 100 miles away from the heavy fighting
