I find this whole topic very interesting. I was in the Army Infantry from 93-97'. I couldn't see even trying to make the transition to minimal shoe running during that time. I'm not so sure about the Air Force or Navy, but I would have wrecked myself if I tried to transition. You show up for PT in the morning and you do what they tell you too. So if you show up wearing minimal shoes for the first time and are told you are doing an 8 mile run, you can't say "but I'm trying to build up my milage gradually". Nope....you're doing 8 miles. It would have been a recipe for injuries for me.
