I'd go anti MEQ, with 2 plasmaguns, bolters, the extra combibolter and an asp champ. with power weapon. smokes and extra armour. use the side and rear exits wisely and stay cover with them. alternatively, flamers, for anti tyranids, eldar, IG, orks, anything but MEQ. 2 flamers instead of the plasmaguns, and a combiflamer on the rhino, perhaps even on the asp. champ.
