I am contemplating joining the military, and cannot decide between our air-force or the Marines?

At the end of Marine boot camp the sergeant says "Congratulations! You made it! You're one of us now!"

At the end of Air Force boot camp the sergeant says "You dips**ts aren't fit to serve but I can't legally keep you any longer. Get out of my sight!"

And it never changes much for the rest of your enlistment.
