Carbine on a captain can be nice if your using him with the "Got Your Six" skill to shoot potential chargers, templates are a bit more accurate then weapons fire as the scatter can still hit even if you miss (a real possibility with enforcers BS)
Aside from that the list looks solid, id consider dropping the vigilance shield and the dum dum rounds to get your pistol wielder a boltgun, and id move any grenades you're buying onto the grenade launcher for the extra range, but thats a matter of taste as its just about changing what you first purchases are after a match
