The
United Defense M8 Armored Gun System was a development of the private venture Close Combat Vehicle - Light (CCV-L) and was to have been the successor of the
M551 Sheridan in the 82nd Airborne Division, as well as expected to replace TOW-equipped HMMWVs in the 2nd Armored Cavalry Regiment (Light). Its role in the 2nd ACR was eventually taken by the
Stryker.
