I think my son had a couple of weeks when he recycled and then went back out. Some people can be there for a good part of their initial commitment. I posted this story before. My son's roommate at Norwich was a great kid. Very type A though. Hurt his shoulder in mountain and was in medical for weeks. He begged them on and on to let him go again. He finished Mountain and Florida. The last night they had a very long ruck march. He broke his foot right before and carried his pack, hobbling, to the end of the march. The Ranger cadre, never to compliment anyone, thought he was the best thing since ice cream was invented. The crowded around him(he was in crouches) at graduation. This guy was there 6 or 7 months maybe. Passed even a greater test last year.
