Hmmm...curious.I was 165 pounds (6 feet tall) when I finished Army BCT.Does Air Force Basic Training focus on PT (marching,running,push ups,etc,etc) as does the Army?
My late brother-in-law told me that Navy recruit training had some of that (late 1960's) but we decided that his wasn't nearly as bad as mine (PT-wise,at least)
I was 5' 10 inches tall and we were told, you get 3 square meals a day and no opportunity for snacks {at least for a while}. I ate good, got 8 hours of sleep a day except when I had dorm guard duty and my shift was 2:30 A.M - 4:30 A.M {Ouch!!!}.
Now when I went to tech school at Sheppard AFB in Wichita Falls, Texas, our squadron won the "best of the base". Our prize was getting to march in a parade in downtown. It was in the low 20's with snow flurries, brrrrrrrrrr. It was a nice experience, but it was COLD!!!!!!
My next base was Malmstrom in Great Falls, Mt. There were MANY times when I would wish it would be 20 degrees there. Sometimes there would be two weeks where the high was below zero. The coldest temperature that I saw was 38 below zero. It was butt cold in Montana, but great summers and the scenery in the state of places to visit was something I will never forget.
