I do wonder why a social worker would need to be equipped for night vision, though.
Yep... I interviewed a surgeon who asked to be brought back on active duty; I think he was in his sixties when he came back on active duty and may have still been on active duty in his seventies. A medical examiner testified at a court martial I covered whose dress uniform caused my Public Affairs media escort to ask him questions — the PAO didn't recognize some of the ribbons which turned out to be from the Korean War as a very young man.
