One of the guys at the office tried to join the Texas State Guard. It's not clear if he failed to pass the fitness requirements as he's medically discharged former Army. He reports them as a club that gets to meet on base except when they deploy to help out on floods and other natural disasters. A penpal friend who lives in Minnesota is a retired IT guy. He volunteers for the Red Cross. A couple of times per year he gets on a plane and spends a month somewhere in the world running the computers and sleeping on a cot in response to some weather disaster. He's been to a lot of the Americas at this point. He has never mentioned benefits just that he likes staying involved.
