M8 armored gun system
The M8 armored gun system (AGS), sometimes known as the Buford, is an American light tank that was intended to replace the M551 Sheridan and TOW missile-armed Humvees in the 82nd Airborne Division and 2nd Armored Cavalry Regiment (2nd ACR) of the U.S. Army respectively.
The M8 AGS began as a private venture of FMC Corporation, called the close combat vehicle light (CCVL), in 1983. The Army began the armored gun system program to develop a mobile gun platform that could be airdropped. By 1992, the AGS was one of the Army's top priority acquisition programs. The service selected FMC's CCVL over proposals from three other teams. The service sought to purchase 237 AGS systems to begin fielding in 1997. Key characteristics of the AGS are its light weight (17.8 short tons (16.1 t) in its low-velocity airdrop configuration), field-installable modular armor, M35 105 mm caliber soft recoil rifled gun, 21-round magazined autoloader, and slide-out powerpack.
Though it had authorized the start of production of the type classified M8 a year earlier, the Army canceled the AGS program in 1996 due to the service's budgetary constraints. The Sheridan was retired without a true successor. The AGS never saw service, though the 82nd Airborne sought to press the preproduction units into service in Iraq. The AGS was unsuccessfully marketed for export and was reincarnated for several subsequent U.S. Army assault gun/light tank programs. United Defense LP proposed the AGS as the Mobile Gun System (MGS) variant of the Interim Armored Vehicle program in 2000, but lost out to the General Motors–General Dynamics' LAV III, which was type classified as the Stryker M1128 mobile gun system. BAE Systems offered the AGS system for the Army's XM1302 Mobile Protected Firepower requirement, but lost to the General Dynamics Griffin II—later type classified as the M10 Booker—in 2022.
The U.S. Army recognized the poor performance of the M551 Sheridan light tank in the Vietnam War and began the process of retiring the vehicle in 1977. A small number of Sheridans were retained in active service by the 82nd Airborne Division and the National Guard. The Army designated the M3 Bradley armored reconnaissance vehicle to partially fill the Sheridan's role.
In the 1980s, the Army began looking for a more capable replacement for the Sheridan. During this time, a string of Army projects to update or replace the Sheridan were begun, but all ended without the Army committing to buy. Some of its efforts around this time could be described as hopelessly intermingled.
In 1979, Army Chief of Staff General Edward C. Meyer initiated a transformation of the 9th Infantry Division that would see the light infantry division assume many of the characteristics of the heavy division through an infusion of high or emerging technology. The so-called "High Technology Light Division" (HTLD) would require the procurement of a Mobile Protected Gun, later called the Assault Gun System (AGS), and a Fast Attack Vehicle. The notional Mobile Protected Gun was to be armed with a kinetic gun, or possibly a missile, capable of defeating enemy armor.
The lack of a production-ready assault gun was one of the key problems in the development of the division. Originally conceived to be a wheeled light armored vehicle armed with a hypervelocity missile as its major tank-killing system. In 1980, the U.S. Army Infantry School's Mobile Protected Gun project analyzed anti-armor weapons systems, concluding that the Army should equip its new light infantry divisions with TOW-armed Humvees and an unspecified 6×6 lightly armored vehicle armed with a 25 mm caliber gun. This led the Secretary of Defense to direct the Army to use the LAV-25 for this purpose. In 1981, the Army joined the Marine Corps's (USMC) Mobile Protected Weapon System program, which then became known as the Mobile Protected Gun System (MPGS). However due to differing requirements, the Army and USMC ended their partnership the following year to embark on separate programs.
The Army and Marine Corps were at the same time also involved in the joint LAV program. At the time, the Army planned to acquire 175 LAV-25s to fully equip the 9th Infantry Division. These interim MPGS's would be armed with a M242 Bushmaster 25 mm cannon, with seating for the passengers replaced with ammunition racks. The Army planned to incorporate the LAV in the 9th Infantry Division as an interim armored gun system. The Army planned to replace this LAV beginning in the late 1980s with the "far-term" MPGS armed with a 75 mm gun. The Army's commitment to the program wavered somewhat, which caused Congress to withhold money for the LAV. The Army withdrew from the LAV program in December 1983.
