Name, Rank and Serial Number
The men of the 23rd Headquarters Special Troops, aka The Ghost Army, then and now. Whenever I interview someone, I tell them that the first question is the hardest. Then I ask them to tell me their name, their title (or rank, in this case) and spell their last name. This video is made up of some of the answers to that first question from each interview.
