The M833 was designed as a replacement for the M774 round, and was classified for US service in 1983. Like its predecessor, it was designed to be fired from the M60 Patton and the original M1 Abrams tanks, both of which were fitted with the 105mm M68 gun.

The training alternative to the M833, manufactured by General Dynamics was the M724A1 TPDS-T round. In 1994 foreign sales of the M833 to Bahrain were authorised. Sales to Israel (300 rounds), Jordan (2,130), Pakistan (10,025), Saudi Arabia (320) and Turkey (22,920) are also recorded.

The M833 is no longer produced in the US, and is not thought to currently be in service. It has been replaced by the M900. Both the M60 series and the M1 Abrams are out of service in the US, but the M60 was exported to numerous countries, and is still in service in many of them.

Although the M833 is only thought to have been fired from the M60 and M1 tanks, in theory it is also capable of being fired from the following guns:

  • L7, a rifled British Gun used on the Centurian Tank, and also used in the German Leopard 1, Japanese Type 74, Sweedish Stridsvagn 103, Indian T-55A, and the Israeli Merkava. The M68 is actually a US licensed version of the L7. It has been reported that the L7 has also been adapted to fit Soviet built T-54 and T-55 tanks by Israel, Eqypt and Iraq, and Chinese Type 79 tanks.
  • Rh 105 smoothbore gun, developed privately by Rheinmetal of Germany, and not known to be fitted to any vehicle. The ammunition designed to work with this gun is a scaled down version of Rheinmetals 120mm rounds, and consists of a high explosive round, and an APFSDS-T round with a tungsten penetrator
  • CN105F1, manufactured by Nexter, fitted to the Giat Industries AMX-30 French tank. The AMX-30 has been largely supersceded by the Leclerc
  • GT7, manufactured by Denel of South Africa, and fitted to the Rooikat 105 Armoured fighting vehicle

The M68 cannon has also recently been fitted to the US M1128 Stryker Mobile Gun System, which fires a number of rounds including the M900, sucessor to the M774.
