My cousin went in at 17,he's out now with 20 years in and a decent pension, at 37 he put his training to work and started a medical consulting firm. He lives by the ocean in Florida. My oldest son went in at 18,one tour North Dakota-one tour Japan-He is now in Alaska and doesn't want to leave when his tour is up. We visited him and his family there and i don't blame him for not wanting to leave,but he wants to get his 20 in and he's halfway there. Ben
