Troop E, 256th Cavalry

Troop E, 256th Cavalry was the armored cavalry reconnaissance troop of the 256th Infantry Brigade of the Louisiana Army National Guard from 1967 to 1995. It was the only unit assigned to the 256th Cavalry parent regiment under the Combat Arms Regimental System, which carried over to the replacement United States Army Regimental System.

The original Troop E was redesignated from a previous armored cavalry unit at Hammond, but a 1971 reorganization resulted in a new Troop E being redesignated from an engineer unit at Leesville while the Hammond unit became engineers. Six years later, another reorganization switched the roles and designations of the Leesville unit and a Natchitoches infantry unit. The troop was called up for the Gulf War in 1990 but did not deploy. The Natchitoches unit was redesignated as Troop A, 108th Cavalry, in 1995.
