The Distinctive Unit Insignia (also called a unit crest) of the 19th Engineer Battalion was approved on 19 December 1952 while the unit was designated as the 19th Engineer Combat Battalion. It uses the shield of the 36th Engineer Regiment’s coat of arm, with the addition of a border, to indicate the Battalion’s descent from that organization. The wavy line represents the sea, the sea horse is a symbol of amphibious operations performed by the Battalion, including marine transportation services; it also inspired the official unit nickname of “Seahorse.”
The Battalion motto of ACUTUM ACUMEN translates into English as “Sharp Ingenuity.”
Currently assigned to the 20th Engineer Brigade and headquartered at Fort Knox, Kentucky, the 19th Engineer Battalion traces its roots back to the formation of the 36th Engineer Regiment, constituted in the Regular Army on 1 October 1933. The Regiment was broken up in 1945 after having taken part in ten campaigns during World War II, five involving amphibious assault landings, and its 3rd Battalion was redesignated as the 2828th Engineer Combat Battalion; the 2828th was subsequently redesignated as the 19th Engineer Combat Battalion (1947) and finally as the 9th Engineer Battalion (1953).
During the Vietnam War, the 19th Engineer Battalion served from March 1965 until June 1970 and was honored with a Valorous Unit Award and a Republic of Vietnam Civil Action Honor Medal, First Class. It would next see action in the First Gulf War, where it earned two campaign streamers, and then in the War on Terrorism, where it was credited with two campaigns each in Afghanistan and Iraq and awarded two Meritorious Unit Commendations.
