FWIW, I don't know if my old buddy is a FReeper but I remember him telling me he could drink his commanding officers under the table. Sharing hangover-war stories with his superiors made him popular. And popularity sometimes has its advantages in the military.
A side note - when I was in, no one ever tried to force me to smoke or drink. In boot camp, the CC's would call smoke and coke breaks. Everybody went in the big lounge and had a smoke and/or a coke. Those who did not smoke were not forced to do so. So, I never understood why some people thinks the military forces people to smoke.
