From June to December 2003, members of the 11th ACR deployed to Afghanistan, where they helped to develop and train the armor and mechanized infantry battalions of the Afghan National Army.

In April 1933, the regiment assumed command and control of the Monterey Civilian Conservation Corps District until mid-1934 and supported the construction and supervision of CCC camps in northern California from 1933 to 1939.

They then moved to Camp Gordon on 1 June 1944 and then departed the New York Port of Embarkation on 29 September 1944, and arrived in England on 10 October 1944, and landed in France on 26 November 1944.

Placed 17 June 1986 under the United States Army Regimental System Inactivated 15 October 1993 – 15 March 1994 in Germany Activated 16 October 1994 (less 3d and 4th Squadrons; the Air Defense Artillery Battery; and the Howitzer Batteries, 1st and 2d Squadrons) at Fort Irwin, California As part of the Gyroscope unit rotations, the 11th ACR was sent to West Germany in March 1957 for another round at the border surveillance mission along the Iron Curtain, replacing the 6th Armored Cavalry Regiment.

[6] The regiment's modifications emphasized the use of ACAVs instead of the Patton medium tank and completely replaced the M-114 found in reconnaissance platoons, which may have existed in European and CONUS areas of operation.

While ACAVs did not have a cannon, the Sheridan's high recoil from its 152mm main gun negated it from firing excessive broadsides while moving down a road.

Operation Hickory (7–15 October 1966) produced the first enemy casualties inflicted by the 3rd Squadron and elements of the 919th Engineer Company in the vicinity of Phu Hoa.

The 1st and 2nd Squadrons operated in the infamous "Iron Triangle" region near Ben Cat employing search and destroy tactics, screening and blocking, and security in attacks on successive objectives.

This regimental size operation conducted RIFs in Binh Long and Tây Ninh Provinces and opened Route 13 to military traffic for the very first time.

Word was received by the II Field Force HQs to immediately re-deploy to the Long Binh/Bien Hoa area to relieve installations threatened by the Tet Offensive.

[11][12] Brigadier General John Bahnsen, a recipient of the Distinguished Service Cross, served with the 11th ACR in Vietnam, commanding first the regiment's Air Cavalry Troop, and later its 1st Squadron.

The Blackhorse Regiment rotated to southern Germany in May 1957,[15] relieving the 6th ACR, and assumed the mission of patrolling the German-Czechoslovak border until its return to the United States in 1964.

As the need for US forces in Europe decreased, the Blackhorse Regiment was inactivated in a ceremony on 15 October 1993, and the remaining troops departed Germany in March 1994.

Using this equipment and configuration, the squadron performs the first of its two primary missions, acting as a non-permissive opposing force (OPFOR) during ten FORSCOM combat training rotations each year.

In 1906, the 1st Squadron remained in Des Moines while the rest of the regiment deployed to Cuba as part of President Theodore Roosevelt's Army of Pacification.

On 12 March 1916, the regiment received orders to join General John J. Pershing as part of the Mexican Punitive Expedition to pursue Pancho Villa.

The Army reorganizations for World War II eliminated the horse cavalry in 1940 and 1st Squadron traded in "saddles and hooves" for "tracks and steel".

President Barack Obama awarded Alpha Troop of the 1st Squadron the Presidential Unit Citation on 20 October 2009, in recognition of a rescue mission 26 March 1970.

[22] While in the Abu Ghraib sector, 1/11 ACR participated in Operation Thunder Cat along with the 256th Infantry Brigade of the Louisiana Army National Guard.

The 2nd Squadron is part of the Army's Opposing Force at the National Training Center, conducting battle operations in accordance with published doctrine and combat instructions.

The 2d Squadron ("Eaglehorse") was activated on 2 February 1901 at Fort Myer, Virginia, and its military campaign geographic areas include the Philippines, Mexico, Europe, Vietnam, and support in Southwest Asia.

After guarding the US southeastern coast from March 1944 until 1 June 1944, the group moved to Camp Gordon, Georgia, to begin training for overseas deployment, The regiment arrived in the United Kingdom on 10 October 1944.

Later, under the command of Major Michael K. Mehaffey, Air Troop was recognized as the Army Aviation Association of America's (AAAA) Unit of the Year.

Early on 10 April 1991 elements of the squadron were issued no notice deployment orders to self-deploy from Fulda to Diyarbakır, Turkey in support of Operation Provide Comfort.

"Packhorse", was activated in Germany under the command of LTC Ronald Kelly on 17 September 1985 to support the Blackhorse as it patrolled the East-West German border along the Fulda Gap.

The Packhorse provided logistical support during both the frequent regimental maneuvers of the Cold War and at gunnery exercises at Grafenwoehr, where the squadron operated for weeks at a time while the cavalry troops and tank companies rotated through the firing ranges.

They provide serviceable assets which include major assemblies, DLRs (Depot Level Reparables), Repairable Exchange Items and ASL stockage.

This entails repairing and replacing transmissions, steering gears, transfers, fuel injector pumps, differentials, engines, axles and necessary gaskets and seals for various types of wheel vehicles.

This includes forward area resupply point (FARP) and Refuel On the Move (ROM) capabilities in order to support rotational CL III requirements.

Task Force Palehorse provides feedback to units through professional After-Action Reviews and written reports in support of ten National Training Center rotations a year.
