The US Military frequently finds itself in a position where they are in need of personnel that already have training and experience. At times like that, they put out a search for those people with prior service in the Army, Navy, Marines, Air Force, and Coast Guard. No matter which military branch you served in previously, the other military branches are likely to welcome you with open arms - especially if you have skills in areas where they feel they are deficient at the time.
