Such as:
Light Mechs - Mine Laying (they have the speed to advance into territory and lay mines effectively).
Medium Mechs - Smoke Dispensers (as a means to cover their own advance and retreat)
Heavy Mech - Air Strike Specialists (Command Mech speciality).
Assault Mechs - Artillery Specialists (Siege Mech speciality).
(Not too sure on Heavy / Assault. If anyone has an alternative, please suggest it).
