I think it would be very difficult, especially since if he is in fact in Special Operations the operations tempo is extraordinarily high even when deployed. Having been deployed multiple times before leaving the service, the difference in deployment tempo between units and MOSs can be considerable. All the guys who go overseas and get freaking XBAWKS HUEG are, for the most part, FOB bitches. Infantrymen, operators, and other combat troops are generally too wasted after long missions in the heat to worry much about smashing 8oz of chicken, 2 cups of oats and wrecking their already sore legs with some squats.
There were mechanics on FOB i visited that were all juiced and enormous....there were also no vehicles on said FOB, they all had a predictable schedule, and were always at the chow hall. The combat troops, on the other hand, looked like shriveled up, pale ghosts. They worked hard all night, slept all day, and had shitty diets consisting of whatever they could get in between missions. I feel bad for them now, of course I was one of them then too LOL
