In the Air Force, was at home watching it happen. I was down from duty with a sprained ankle, immediately wrapped it up, went to the clinic and got cleared for duty. Within an hour of being brought back up, I was armed and on my way to patrol the missile field for countless hours afterwards. I think I came home four days later long enough to do laundry and went right back out for another 5 or 6 days. As soon as we were in Afghanistan I was tasked with a deployment to go there, we cancelled at the last minute (bags packed, already processed through the mobility line) because it would have been too difficult to backfill us with guard and reserve because of the nuke mission.
Fun times.
