Rendered almost exclusively in crimson and yellow to reflect its origins in the Ordnance Corps, the Distinctive Unit Insignia (DUI) of the 749th Support Battalion—now called the 749th Combat Sustainment Support Battalion—was originally approved for the 749th Ordnance Battalion on 14 August 1957. It has been redesignated four times since then: for the 749th Maintenance Battalion (June 1968), 749th Service Battalion (March 1973), the 749th Maintenance Battalion (September 1980), and with revised symbolism for the 749th Support Battalion on 1 September 2007.
The two intersecting crimson bands represent a walk or walkway, rendered “Alameda” in Spanish for “public walk” and also city that served as the unit’s home area at the time the insignia was approved. On the walk is a spanner, a wrench-like tool that was used to adjust wheel-lock musket. QUITAR FIJAR Y REPONDER, the unit motto, is Spanish for “Remove, Repair, Replace.”
The 749th Combat Sustainment Support Battalion is a unit in the California Army National Guard. Currently headquartered at Benicia, the Battalion is assigned to the 224th Sustainment Brigade, and it previously had been a component in the 115th Regional Support Group.

Also known as a unit crest or DUI, the Distinctive Unit Insignia is worn by all Soldiers (except General Officers) in units that have been authorized to be issued the device. It is worn centered on the shoulder loops of the Army Green Service Uniform (AGSU) and the blue Army Service Uniform (ASU, Enlisted only) with the base of the insignia toward the outside shoulder seam. DUIs are not worn on the Dress variations of either uniform, however.
Full guidance on wear of the DUI is found in DA Pamphlet 670-1,
Section 21-22, "Distinctive unit insignia."
