Well, we have to give them hermetically sealed polytanium armor, and they have to have those 100mm guided mortars and the power cells that keeps them in the field for up to a year without a recharge.
I think we should outfit most of them with twin 120mm turrets off of the outmoded M1A2's and some should have 100mm gatlin cannons.
But this might take a while....
oh man, I want the pods filled with armor piercing rockets - you know, and the energy beam weapons that can melt an opponent's kneecap at a mile and half distance...yeah! now we're talkin'!
