During most of the 1950s the battery and its battalion served with the 1st Armored Division after being reactivated, but again inactivated due to the Combat Arms Regimental System reorganization in 1957.

Under the reorganization the battery became the 2nd Battalion of the regiment, serving with the 3rd Armored Division in Germany for most of the Cold War, before being inactivated and reflagged in 1988.

The battalion was constituted during World War I on 5 July 1918 as Battery B of the 27th Field Artillery, a National Army unit, part of the 9th Division.

The battery was organized on 2 August at Camp McClellan, Alabama, but remained stateside and was demobilized there after the end of the war on 8 February 1919.

[1] On 15 July 1940 the battery was reactivated with the 27th Field Artillery Battalion (FAB) at Fort Knox, assigned to the 1st Armored Division.

The battalion was based at Ray Barracks, Friedberg, Germany, as a direct support unit for the 3rd Brigade of the 3rd Armored Division, armed with the 155 mm self-propelled howitzer.
