16th U.S. Army Signal Battalion DUI Insignia Pin with "Communications First" motto. The pin measures about 1 inch. The back has double clutch holders. Also the back is embossed with military heraldry mark G23 Ira Green Inc. This marking should designate that the pin is from the 1965 to 1967 timeframe (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.
