The 1st Battalion, 40th Field Artillery Regiment (1/40th FA) was originally constituted in the Regular Army in 1918 and has served in various forms ever since. The unit saw notable action during World War II, providing critical fire support in the European Theater, including campaigns in Normandy and the Rhineland. During the Vietnam War, the battalion was deployed to Southeast Asia, where it supported infantry operations with artillery fire and earned multiple commendations. In the modern era, the 1/40th FA has continued its legacy, serving as a key artillery training battalion at Fort Sill, Oklahoma, and upholding its motto, “All for One.”
