Of course. I didn't even go into the MAG gunners number two that carried his personal firearm and the spare belts. The rest of the team also carried spare belts for the MAG but less than number two did. If a PatMor (60mm Patrol Mortar) was carried by the team, everyone carried spare mortar bombs for it too.
I seriously doubt anyone who has not served has any idea of the weight carried on a week patrol including the radio, medical kit, ammunition, bedding food and water. Water weighs 1kg per liter and in waterless areas, a lot has to be carried.
