16th U.S. Army Sustainment Brigade DUI Insignia Pin with "Logistics The Key To Win" motto. The pin measures about 1 inch round. The back has double clutch holders. Also the back is embossed with military heraldry mark V-21 and says Made in U.S.A. This marking should designate that the pin is from the 1965 to 1978 timeframe, which would include the Vietnam era.
The pin is part of a large collection of insignia pins that I purchased at an estate sale. It is attached to a small thin cardboard square. Any writing on the cardboard was put there by the previous owner and that's great because I can't imagine how long it would take me to look up and obtain information on over 700 pins. I'm using his information. He was the expert, so hopefully the information is correct.
