Much hard work to get there.
I'd assume there are many Rangers who are also Green Beret qualified. Almost a year ago I attended my son's Ranger graduation ceremony at Ft. Benning (yep, I was proud). The display of just their skills are simply amazing - especially the hand-to-hand combat. Twenty one years in the Army and it's a world I never really knew.
Ahhh Little Creek Ampib base. The Marines ran their Scout Swim school on the base in the 70s. Three of our teams went up there for some training in the fall one year in the late 70s.
It would be a hard call as to if we had more fun in the water or at the, as we called it, The El Croc-a-dildo all ranks club.
