Just what I was trying to get at, the USMC see themselves as one Elite to the last Marine, though they have a few "Special Talents" they are still Marines First, Last and Always, the USMC tends to sometimes put too high a Premium on the individual value of each Marine, This is Good to make sure you have your mates backs when someone shouts "Contact" and to be 100% sure everyone goes home one way or the other, but it tends to stop them letting Marines go away to the DoD's Schools for the Gifted and picking up useful skills and contacts by doing "Work Experience" out side the Core.
Perhaps someone should introduce the idea of Tiered Elites to the USMC, and having Nads that Clank when you walk (even on the Girls) tends to give your position away to the enemy.
