WW2 US Engineer Officer’s DUI Collar Insignia Single

The WW2 US Engineer Officer’s DUI (Distinctive Unit Insignia) Collar Insignia, offered here as a single piece, is an authentic example of the insignia worn by Engineer officers of the United States Army during the Second World War. This collar device is typically constructed from metal and features the design associated with the Corps of Engineers, most commonly a castle with three towers. Used to identify an officer’s branch of service, the insignia was worn on the uniform collar and served as a symbol of the officer’s role within the engineering branch, which was responsible for duties such as construction, demolition, and support in battlefield conditions. Measuring approximately one inch in diameter, the insignia generally includes a pin-back or clutch-back fastening. This piece reflects the style and specifications regulated during the wartime period and is indicative of the Army’s recognition of specialized functions within its ranks during World War II.
