If the Gunners had to bear heavy machineguns, heavy armor and heavy ammunition, the only thing they would be able to do would be lying on the ground and pushing the trigger.

Carrier appears to be a light armored Western Armaggorian with a huge metal ammo bag on his spine where the 45mm cartridges are kept, armed with AS-43 shotgun for self-defence and back covering purpose. Those guys' battle mission is to stay alive while their gunners are solving problem of enemy army overpopulation.
