They called my stepfather up shortly after September 11th 2001. He told them he still had a souvenir from Vietnam embedded in his backside from his previous employment
Then he became concerned, if they were calling up old men like him perhaps they were in worse shape than he thought. He would have just been assisting with training, not actually going overseas due to his veteran status, but it was still nervewracking.
However, it turned out to be a mistake as someone entered the wrong year on his paperwork. May not be the case next time!
