The 737th Maintenance Battalion Distinctive Unit Insignia, also referred to as a unit crest or DUI, was originally approved on 30 March 1973. Crimson and blue, the dominant colors used for the insignia, are traditionally associated with Maintenance units, while the buckeye at the center is a symbol of the Ohio Army National Guard.
A spear in the center reflects command authority and readiness, while the wrenches bookending the spear symbolize operating efficiency; combined, they represent the overall mission and capabilities of the Battalion. The wrenches and spear are also a reference to equipment and tools used during Battalion operations. “Support Unlimited” was the Battalion motto.
Organized in 1963, the 737th Maintenance Battalion was inactivated in 2007.
The DUI is the picture is the one you will receive.
