if it was a joke.. you can thank your liberal mothers of America... but if you thought it was a joke... try lookin into the Air Force boot camp.. I hear Air Force boot camp you run on treadmills for pt. Out of all the service.. the Marines is the hardest.. however, thanks the mothers of America, Drill instructors cannot Bi@tch slap the shit out of recruits like this guy posting the question.. or at least without being investigated.. believe it or not..
