My BIL is ex Seal, ex Annapolis grad. I don't know much about what he did as he was already out due to a bad knee when he married my SIL & he didn't elaborate much.

After getting out, he worked for DOD until he retired. I do know he went to ME & Afghanistan several times to conduct training.

Shot pistols with him a few times & he could shoot pretty well. Liked Sig's.
