History and lineage

The 189th Field Artillery Regiment was constituted in the National Guard in 1921, assigned to the 85th Field Artillery Brigade (VIII Corps), and allotted to the state of Oklahoma. It was organized and federally recognized on 14 October 1921 by the redesignation of the 2nd Field Artillery Regiment of the Oklahoma National Guard. It was reassigned to the 187th Field Artillery Brigade (VIII Corps) on 2 July 1923. In March 1930, the regiment was relieved from the 187th Field Artillery Brigade and assigned to the 45th Division. The 189th Field Artillery Regiment, consisting of two battalions of 155mm howitzers, truck drawn, was inducted into Federal service on 16 September 1940 and stationed at Fort Sill, Oklahoma. The 189th Field Artillery Regiment moved to Camp Barkeley, Texas on 6 March 1941. On 11 February 1942, the regiment split into two separate battalions, the 1st Battalion, 189th FA Regiment retained the number and remained with the 45th Division. The 2nd Battalion, 189th FA Regiment was redesignated as 202nd Field Artillery Regiment and was assigned to General Headquarters Reserve. The 202nd Field Artillery Regiment was further reorganized on 1 March 1943 when the 1st Battalion was redesignated as the independent 202nd Field Artillery Battalion and the 2nd Battalion became the 961st Field Artillery Battalion. The 189th fought in Sicily, Italy, France, and Germany during World War II, receiving the Presidential Unit Citation for action on the Salerno Beachhead. The battalion was recalled to active duty in 1950 with the 45th Infantry Division and fought in Korea.[1]
