Due to differences between the organization of Regimental Cavalry Squadrons and Divisional Cavalry Squadrons, in 1st Sqdn 11th ACR, the Sheridans were issued to the ACAV Troops, replacing three M113 ACAVs in each platoon (the squadron's one tank company remained intact); in 3rd Sqdn, 4th Cav, the Sheridans replaced M48A3 tanks throughout the squadron.

Although the 3/4 Cavalry met near disaster with their Sheridan's within a month of receiving them (one destroyed by a mine), the 1/11 Cavalry had just the reverse in luck, killing nearly 80 enemy soldiers during an engagement on 23 February 1969. All things considered, the army was satisfied with the Sheridan tank, and by the end of 1970 alone, well over 200 M551s would be in South Vietnam.

 light tanks could effectively and safely conduct "thunder runs"; the firing of all tank weapons while driving down the highway or road. 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. Thus the most favored tanks for clearing highways with thunder runs on a daily basis, most often fell to the M48s of the 11th ACR and accompanying armor units.

Blackhorse was brought back into active status 1 April 1951 at Camp Carson, Colorado. In 1954, the Regiment transferred to Fort Knox, Kentucky to complete its training in fully armored tactics.

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

The Blackhorse arrived in Vietnam on 7 September 1966. Second Squadron spearheaded Operation Fish Hook into Cambodia on 1 May 1970, surrounding a North Vietnamese logistics center.

In 1972 the 14th Armored Cavalry Regiment, which had the mission of patrolling the East-West German border, was redesignated the 11th Armored Cavalry Regiment at Downs Barracks.

As the 2nd Brigade Tactical Group, the Squadron trains brigade and battalion task forces during ten rotations a year at the National Training Center.

1st Squadron

The 1st Squadron is organized as an armor battalion, and comprises one of the two maneuver elements of the 11th ACR.

"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 squadron's official name at that time was Combat Support Squadron (CSS). The nickname "Packhorse" is derived from the early days of the U.S. Cavalry, when soldiers went on campaigns accompanied by packhorse
Packhorse
.A packhorse or pack horse refers generally to an equid such as a horse, mule, donkey or pony used for carrying goods on their backs, usually carried in sidebags or panniers. Typically packhorses are used to cross difficult terrain, where the absence of roads prevents the use of wheeled vehicles. ...

s, additional horses and/or mules that carried all their essential supplies. Everything from food to gunpowder to horseshoes were transported in this manner.

Initial organization included five units—Headquarters and Headquarters Troop, Maintenance Troop, Supply and Transportation Troop, Medical Troop, and the attached 54th Chemical Detachment. The squadron also operated the Regimental Material Management Center which had the responsibility for the overall logistics state of the regiment. Elements of the squadron were based at both Fulda and Wildflecken

Wildflecken is a municipality in the Bad Kissingen district, at the border of northeastern Bavaria and southern Hesse. In 2005, its population was 3,285; the postal code is 97772. Wildflecken is in the picturesque Rhön hills and nature-park....

. The squadron was large for a battalion-sized unit, as the Maintenance Troop alone had some 400 soldiers assigned. 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.

 5-ton Expansible Vans ("Expando-vans") housed the squadron headquarters in the field. The squadron was also capable of highly specialized functions such as the provision of potable water by filtering fresh water sources through purification units.

On October 3 1990 the Two Germanys Re-Unified. By December 1991 the Soviet Union dissolved. The Squadron's six-year presence as the supporters of the "Eyes and Ears" of the U.S. Army along the Iron Curtain was over. In August 1990, Iraq invaded Kuwait, prompting the United States to respond.

On 16 May 1991, the Packhorse received orders to deploy to Kuwait to support the Regiment as it secured the country while it struggled to rebuild after the war. By October, the Regiment had completed its mission and the Packhorse returned to Fulda. As the need for U.S. forces in Europe decreased, the Packhorse was inactivated on 15 February 1994, followed by the Blackhorse on 15 March 1994.

Reactivated on 15 October 1994, the Packhorse once again had postured itself to provide world class logistical support to the 11th Armored Cavalry Regiment as it defended the sovereign land of Mother Krasnovia as the U.S. Army's Opposing Forces at the National Training Center.

Since its reactivation the Support Squadron's accomplishments are many. The Support Squadron has been the Forces Command (FORSCOM) winner of the Philip A. Connelly award for garrison food service excellence in FY 1992, 1993 and 1994. The squadron also won this same competition at the Department of the Army (DA) level in FY 1993. The squadron was a major player in the regiment's selection as the only Army unit in the Department of Defense for the Phoenix award for Maintenance Excellence in FY 1995, FY 1999 and FY 2000. Headquarters and Headquarters Troop was the winner of the DA Award for Maintenance Excellence for FY 1995 and FY 1996 in the Intermediate Equipment Density Category, the only unit to do so in the 16-year history of the program.

Maintenance Troop was recognized as the Salute Magazine Unit of the Year for 1995; this competition included units from all branches of the service. The 58th Engineer Company placed 4th in FORSCOM in the DA Award for Maintenance Excellence in the Heavy Equipment Density Category in FY 1995, and were 3rd place winners in FY 1996 and FY 1997. The 511th Military Intelligence Company placed 3rd in FORSCOM in the separate Company category for the Army Supply Excellence Award and was the Starry Award winner for being the best company in the Regiment during 2000.

The Squadron also won the FY 2002 FORSCOM Competition for both the Supply Support Activity (SSA) and Squadron Supply Operations, the SSA also subsequently received Runner-up at DA Level for FY 2002. Currently, the Squadron participated and won the FORSCOM level in the Philip A. Connelly competition for best Field Feeding Crew of FY 2003. Supply/Trans and Maintenance Troops competed and won the Army Award for Maintenance Excellence in FORSCOM for FY 2003; both are currently competing at the DA level. The squadron also placed first in the FORSCOM level of Army Supply Excellence for FY 2004 in Squadron Supply Operations and the SSA; both are also currently competing at the DA level.

It is only by experience on the job that the soldier decides on how a vehicle will be recovered.

The section is composed of 44E and 44B MOSs, welders and machinists. They can manufacture a functional part from a piece of metal or they can fabricate anything within the limitation of the equipment they have.
