The backpack is no longer a carrying area for extra ammo it is a radio. The thing in front of their eyes helps them see in the dark and lock on to targets. The radio operater can only carry whatever he/she cah fit on their armor. Usually that is 1 or 2 pistols and a Saw Happy or some other assualt rifle. Their helmet is specially made to reduce noise and all ow them to wirelessly use the radio. Helmet by Oldbridge?
