Attachments for utilities like the RPG, talon, stim gun, and grenade launcher. You would get the stim gun attachments by healing your teammates instead of kills. These attachments would be:
(RPG - faster rockets, faster reload, bigger explosion, and more damage to foot soldiers)
(Talon - faster rockets, faster reload, and faster tracking(makes the square turn green faster))
(Stim gun - more overheal, longer stim, and extended magazine)
