Travel a fair distance away from eachother to avoid the detection of the squad.
Stay back and report sightings if target is too hot for infiltration.
The sniper should watch over his squadmates to provide cover. If one squadmate should die, the sniper should take him out and then cover the man down to provide cover for the Adv. Med.
The Adv. Med. should only try to revive if they have a clear opening.
The Adv. Hacker will always be the point man, so as he can hack door locks, and enemy vehicles.
The Combat Engineer should set deployables right after a capture.
If the sniper goes down, the Adv. Med. shouldn't have a problem reviving them, because the Reaver, and Mosquito pilots rarly ever turn on DL while flying.
