When I was in the service I rode in those things and was pulled on skis behind them. Cold weather training Bridgeport, Ca.
My son was in the truck company at Camp Marguerita, Camp Pendleton. Since he had no license, they of course had him driving a 5-ton truck. but he signed up for all the training he could get approved, including Bridgeport. He was the only one in his class who could ski, so they sent him out to dig out snow banks and places to sleep. Got a lot of skiing in.
He came back and get accepted for embassy duty MSG.
