The 623rd Field Artillery Regiment (Morgan's Men) is a single-battalion unit of the Kentucky Army National Guard.

The unit was mustered into Federal Service for a year before returning to the state as separate militia companies.

With the coming of the American Civil War in 1861 the unit broke up as men joined the Confederate or Union forces.

The unit was demobilized in January 1919 and reorganized in 1920–21 to form the 1st Infantry Regiment and the 53d and 54th Machine Gun Squadrons.

The 106th mustered into Federal Service in 1941 and was redesignated as the 106th Antiaircraft Artillery Automatic Weapons Battalion on 14 July 1944.

It was equipped with the M110A2 howitzer and, as part of the XVIII Airborne Corps, advanced as far as Basra before the war ended.

The unit was reorganized as 1st Battalion, 623rd Field Artillery (MLRS), on 15 December 1994, after receiving the M270 Multiple Launch Rocket System.

[3] The 623rd took part in the June 2018 Operation Saber Strike United States Army Europe and Africa training exercise in Lithuania, supporting the regular 2nd Cavalry Regiment.

[4] The special designation (official nickname) of the 623rd Field Artillery Regiment is "Morgan's Men", in reference to its Confederate lineage.

[5] Following the 2020 murder of George Floyd some Army commands have phased out Confederate references; a December 2020 law mandated the removal of Confederate-related names from United States Department of Defense property.

The red and yellow are the traditional colors of the field artillery while the blue of the horse's head alludes to Kentucky being the Bluegrass State.

Battery B (Campbellsville) was additionally awarded a Philippine Republic Presidential Unit Citation with streamer embroidered "17 October 1944 to 4 July 1945" for service in the Pacific Theater of World War Two.
