yossam1- Make sure you ask for the right thing, the regular troop transport, mostly called a "slick" had a M-60, very occasionally 2 - M-60 "30 cal" MG in each side door, the gunships had other stuff, I think most had a 40 mm automatic grenade launcher in a chin turret under and a "30 cal" (actually 7.62mm) minigun in front, plus rocket launchers, I can't recall them having door guns, but maybe they did.
