Scott would absolutely join in an organized effort. He's got his biotics that can toss things, pull things, smash things, and protect people with a bubble for a limited time if there's anyone who needs to be quickly taken out of the battle for whatever reason. He can get some air with it too, like basically super powered jumps? He's good at being offensive but would probably help best from a defensive standpoint, like keeping things off of other people, etc!
