Alright, if anyone's still considering it I thought of a fireteam organization. Like [@Sola] pointed out on the interest check, there could be a sniper/spotter dynamic; however, in a more flexible environment, there could be a close-range/mid-range/long-range setup. For instance, a 'scout' with a shotgun/SMG, 'leader'/'support' with an assault rifle/LMG, and a 'sniper' with [s]either a composite bow or blowgun[/s] a long-range rifle. This could in theory allow for both effective overwatch cover and leapfrogging.
