A tank destroyer, tank hunter, tank killer, or self-propelled anti-tank gun is a type of armoured fighting vehicle, armed with a direct-fire artillery gun or missile launcher, designed specifically to engage and destroy enemy tanks, often with limited operational capacities.

The 2S25 Sprut-SD is a self-propelled tank destroyer or light tank developed and manufactured by the Russian defence company, Volgograd Tractor Plant joint stock company, to meet the requirements of the VDV.

The FV1620 Humber Hornet was a specialised air-deployable armoured fighting vehicle designed to carry the Malkara, an anti-tank guided missile developed by Australia and the United Kingdom.

The IT-1 was a Soviet cold war missile tank based on the hull of the T-62. The tank fired specially designed 3M7 Drakon missiles from a pop-up launcher. It saw a very limited service between 1968 and 1970. The large deadzone around the tank created by the missiles' minimum range combined with the limited amount of ammunition carried made it unpopular with the military. Also, the 520 kg of guidance equipment needed for the missile was impractical. Eventually, the tanks were converted into recovery vehicles. A turbine-powered version was also developed named the IT-1T.

A missile tank is an armoured fighting vehicle fulfilling the role of a main battle tank, but using only guided missiles for main armament. Several nations have experimented with prototypes, notably the Soviet Union during the tenure of Nikita Khrushchev, but only the West German Jaguar 2 saw service as a standard vehicle, although the Soviet IT-1 missile tank also saw limited service.

The Nahkampfkanone 1 was an experimental Swiss tank destroyer that saw service between 1944 and 1947. Only one was ever built.

The SU-14 was a prototype Soviet heavy self-propelled gun built on a T-35 chassis. The original prototype mounted a 152 mm gun M1935 (Br-2); the SU-14-1 variant of 1936 carried a 203 mm gun B-4 which could fire 48.9 kilogram shells at ranges up to 25 km. Its armour was 20 to 50 mm thick. It never entered serial production.

The Vespa 150 TAP was an anti-tank scooter made in the 1950s from a Vespa scooter for use with French paratroops. Introduced in 1956 and updated in 1959, the scooter was produced by Ateliers de Construction de Motocycles et Automobiles (ACMA), the licensed assembler of Vespas in France at the time. Modifications from the civilian Vespa included a reinforced frame and a three-inch recoilless rifle mounted to the scooter.
The Versuchsträger 1-2 were two German prototype twin gun turretless main battle tanks. Since the early 1970s a number of West German companies have been working on conceptual designs for a successor to the Leopard 1. This project had the name Kampfpanzer 3. The KPz 3 project was temporarily a British-German joint project, until the UK withdrew because they wanted a turreted tank. The Germans had already developed the Leopard 2 and therefore didn't see the need for another conventional tank. One of the companies involved was MaK, developing the VT 1-1 and VT 1-2. The test programme ended proving that a twin-gunned turretless tank could be created with enough technical effort, but had drawbacks in both practical and tactical use.
