Its the same dang way across the board almost.. Marines, we have whats known as a cutting score once u try and hit E-4 or E-5.. It comes down to who blew better to get a better pro/con score, who shoots better(i.e. who got the most love from the pit), who gets the highest PFT score(PULL ups, crunches, 3 mile run), and who doe sthe most off duty education. all of that goes into your cutting score. Yeah we live in barracks, but at least it isnt squad bays like it was in boot camp or the "old corps".
Air force is the way to go if you are book smart, outta shape and lazy and dont want to get hurt, dirty, cut, scraped, cold, hot, sweaty, sick, insomnia, sore shoulders, lack of food, when you do get it cardboard tastes better, etc etc.
But i Love my Corps. I have no regrets. Its just the BS that you get used to and learn to live it love it cherish it. The Few, The Proud, The MARINES! oorah, kill, yutt and all that other happy horsesh!t
