most of my mecha , even ones not designed for anti air missions are fitted with what i call the 'Litter Box' a small compact scatter shot box of small SAM missiles , each one emits a high heat signature , and is packed with Electronic counter measures , designed to confuse the targeting computer of incomming missiles and planes
each warhead is also a small flash bang , which is designed to obscure the vision of pilots in low flying aircraft
eh true, maybe if you gave it a detachable feature. Like the arms that hold the gun detach and the mech has little stubby fingers that can slide out of the wrists. o_O I don't know. I like mech's with hands.
