The unit was first constituted 19 November 1917 as Headquarters Battery, 4th Field Artillery Brigade, and assigned to the 4th Infantry Division. The unit was organized for combat operations at Camp Greene, North Carolina from 15 December 1917 to 10 January 1918.

Upon returning stateside, the 4th Field Artillery Brigade was stationed at Camp Lewis, Washington, where it was inactivated 21 September 1921. 4th Field Artillery Brigade was redesignated as Headquarters and Headquarters Battery, 4th Field Artillery Brigade at Fort Sill, Oklahoma, 1 January 1935, and then disbanded 14 November 1939.
