A new character concept for military operations in RPG

I think the chain of command is a witch with a Bee for running a classic rpg campaign involving military operations. New thought: each player has a squad of thinly made characters with perhaps a more fully fleshed out squad leader. Anyone can get killed and if they do the player picks a new squad leader. When i say thinly fleshed out I mean the character sheet holds the whole squad on one sheet of paper. If you need some role play encounters you just use the squad leader or even just use one of the squad characters. The game at the table top would play out like a skirmish level wargame for simplicity and fast play. In PBP it would play out with each squad having a thread where they work toward the individual squad's objective. In a pick your path book it would play out as resource management to not lose everyone in the squad before finishing the book. One player might be running a jet copter and crew while another a squad of grunts. No player is really giving orders to another and they are still working cooperatively. Squad exp given based on how well each squad reached their obective (pretty much like wargame victory conditions).
