I was one of the skinny ones, gained 40 lbs in basic. They didn't give me choclit milk or bananas, though. I was hungry all the time, first thing I did when I got a pass out of the company area was run down the street to a diary queen kind of place and get a big chocolate malt and cheeseburger. Last duty station had a place on base with big chocolate malts, big cheeseburgers, and a big bowl of chili for something like a buck & a half. My lunch 3 or 4 times a week. I'd weigh 300 lbs next month if I ate like that now.
Morning Moldy and Russ! I used to make my own milkshakes with raw eggs and Hershey syrup to gain weight, don't seem to have that issue any longer either.
