if every level was with your squad there'd be too much memory, because then they'd have to have complicated scripting, i mean just having powell kill ppl is hard enough to make, but have your whole squad kill ppl, it would be too difficult, and boring to play over and over again, because they cant make your squad members do different things everytime.
