“Roulons Et Passons,” the unit motto inscribed on the Distinctive Unit Insignia—more commonly referred to as a unit crest or a DUI—of the 3rd Brigade Support Battalion, 1st Armored Brigade Combat Team, 3rd Infantry Division, is roughly translated as simply “Let us roll and cross,” but is understood to mean “Let us roll (forward) and cross (the bridge at Chateau-Thierry).” This is a reference to the unit’s first action in World War II when it was designated as the 3rd Supply Train, 3rd Division and took part in the Allied counterattack at the Second Battle of the Marne.
The five-spired fort at the bottom of the shield is emblematic of Chateau-Thierry, the town closest to where the Battalion first saw action on 18 July 1918. By the time the armistice was signed some four months later, the unit had taken part in five campaigns with the 3d Division. During World War II, the Battalion—now fighting as the 3rd Quartermaster Battalion—earned credit for participating in twice as many campaigns, beginning with the Allied invasion of North Africa in November 1943; four of those campaign awards included the coveted Arrowhead device indicating the Battalion had been part of a planned assault landing.
Full guidance on wear of the DUI is found in DA Pamphlet 670-1,
Section 21-22, "Distinctive unit insignia" and 21–3(d) and (e),
"Beret" and
"Garrison Cap," respectively.

The unit has undergone several redesignations and reorganizations over the decades since it was originally constituted as the Motor Supply Train, 3rd Division, but it has always served in a support role and always with the 3rd Division (later 3rd Infantry Division). Designated as the 3rd Forward Support Battalion in May 1987, the Battalion was redesignated as a Brigade Support Battalion in 2004 as part of the Army’s reorganization around modular brigades.
The 3rd Brigade Support Battalion is currently headquartered at Fort Stewart, Georgia.
