I thought I'd let someone answer first and then I'd go. I'd also change the specialities around a bit. I'd have 2 small teams and 1 overall commander. Therefore, it'd look a LOT like this (course, I'm pretty readable so you guys will kjnow who I'll be giving love!) :

General Hawk (v2, of course). Top guy. Hands out the orders, make sure the team is doing what they are supposed to be doing. Etc.

RRTS1.
Lt. Falcon. Leads the posse. Acts as communication since he has the pack.
Beach Head. If you break them into 2 squads on the team, Beach Head leads the other members.
Tunnel Rat. Acts as scout, EOD, tunnel guy and basic infantry.
Repeater. Heavy gunner.
Snake Eyes. The fighter, infantry, etc.
Bombstrike. Sniper, computers and infantry.

RRTS2
Flint. Leads the back-up unit BUT acts as primary rescue ops.
Stalker. Leads the 2nd half of the RRTS2. Acts as medic & EOD.
Gung Ho. As seen in Transformations, heavy weapons operator.
Crosshair. Sniper, infantry, etc
Dart. Scout, weapons knowledge, infantry, etc
Scarlet Undercover, fighter, infantry, etc.
