WThe Armored Gun System, or AGS for short, was a US Army competition in the 1980s to design a light tank to replace the M551 Sheridan and TOW-equipped HMMWVs. It was the ultimate incarnation of several research programs run in the 1970s with the aim of providing air-mobile light infantry forces with the firepower needed to last in the battlefield.
WThe United Defense M8 Armored Gun System was an American light tank that was intended to replace the M551A1 Sheridan in the 82nd Airborne Division, as well as being expected to replace TOW-equipped Humvees in the 2nd Armored Cavalry Regiment. The M8 project was eventually canceled in 1997. Its role in the 2nd ACR was eventually taken by the M1128 Mobile Gun System, but a modernized version of the vehicle is in trials with the US Army once more.
WThe "Patagón" tank is a light tank developed in Argentina during the early 2000s, expected to enter service with the Argentine Army. It is based on a SK-105 Kürassier chassis with a refurbished AMX-13 turret. The project was cancelled in late 2008 after five tanks were converted.
WThe Ripsaw is a series of developmental unmanned ground combat vehicles designed by Howe & Howe Technologies for evaluation by the United States Army.
WThe Stingray, sometimes known as the Commando Stingray, is a light tank produced by Textron Marine & Land Systems division. It was specifically designed to use as many existing components of other American armored fighting vehicles as possible to keep costs down. The Stingray was a private venture project aimed at foreign countries. As of 2020, Textron has kept the Stingray name registered.
WThe Type 63A is an amphibious light tank upgraded from the Type 63, designed for river-crossing operations at inland rivers and lakes. Its industrial designation is WZ213.
WThe Type 05 amphibious armored vehicle is a family of amphibious tracked armored fighting vehicles developed by Norinco for the People's Liberation Army Navy Marine Corps, consisting of two main combat variants — the ZBD-05 infantry fighting vehicle and the ZTD-05 assault vehicle, as well as two support variants based on the ZBD-05. The Type 05s could be launched at sea from an amphibious assault ship over the horizon, and features a hydroplane, a design concept that has been compared to the cancelled United States Expeditionary Fighting Vehicle (EFV) program.
