The VFM5 is a British-American prototype light tank developed in the 1980s by Vickers Defence Systems and FMC. It combined high mobility with a 105 mm L7 gun on a lightweight, air-transportable chassis weighing about 19–20 tons. Powered by a 550 hp Detroit Diesel engine, it was fast and agile but had thin aluminum-steel armor, making it vulnerable in direct combat. Never mass-produced, the VFM5 remains known mainly through games like War Thunder and Armored Warfare.

The FV510 Warrior is a British infantry fighting vehicle introduced in the late 1980s. Armed with a 30 mm RARDEN cannon and a 7.62 mm machine gun, it carries three crew and up to seven infantry. Powered by a 550 hp diesel engine, it offers good mobility and protection for its class. The Warrior has seen service in the Gulf War, Iraq, and Afghanistan, and remains in use with upgrades despite plans for replacement.

The Vickers Mk.11 was a British 6×6 wheeled prototype from the 1990s, armed with a 105 mm gun and carrying up to 11 crew and troops. Fast and mobile but lightly armored, it stayed a prototype and was never adopted.

The Challenger 3 TD is the prototype of the UK’s next main battle tank, fitted with a 120 mm smoothbore gun, upgraded armor, and modern systems. Weighing about 66 tons with a crew of four, it tests new features ahead of full Challenger 3 service planned from 2027.

The Challenger 2 Black Night is a 2018 upgrade prototype with improved armor, thermal sights, and an active protection system. It kept the 120 mm rifled gun but was not adopted, being replaced by the Challenger 3 program.

The Vickers Mk.7 was a 1980s British prototype tank combining a Challenger 1 turret with a German Leopard 2-style chassis. Armed with a 120 mm gun, it was never adopted or exported.

The Churchill-IV was british infantry tank used in world war II. It was similar the churchill III but built with minor improvements and equipped with a 6-pounder(57mm) gun. Like other churchill, it was heavily armored,slow and designed for infantry support across rough terrain 

The Churchill-I tank had many variants, from 2-pounder models to later 75 mm guns, including specialized versions like the crocodile flamethrower 

The Conqueror was a 1950s British heavy tank with a 120 mm gun and heavy armor, built to counter Soviet IS-3s. Powerful but slow and unreliable, only about 185 were made before retirement in the 1960s.

The British ADATS was tested on a Warrior chassis in the 1980s, using dual-role missiles against aircraft and tanks. Advanced but costly, it was never adopted.

The Rapier is a British short-range surface-to-air missile system introduced in the 1970s. Designed to defend against aircraft, it uses radar and optical guidance for high accuracy. Highly mobile and widely exported, Rapier served with the British Army and Royal Air Force until it was retired in the 2020s.

The Stormer HVM is a British air-defence vehicle carrying Starstreak missiles on a fast, tracked chassis. It protects against low-flying aircraft, helicopters, and drones.

The FV102 Striker was a British tracked anti-tank vehicle based on the CVR(T) family. Entering service in the 1970s, it carried five Swingfire guided missiles ready to fire, with additional reloads stored inside. Light and mobile, it gave British forces long-range anti-tank capability until retired in the 2000s.

The Swingfire was a British wire-guided anti-tank missile from the 1960s, steerable after launch with a 4 km range, used on vehicles like the FV102 Striker until the 1990s.

The Conway (FV4004) was a British post-war heavy tank destroyer based on the Centurion chassis. It mounted a large 120 mm L1 gun in a tall, boxy turret to counter Soviet heavy tanks like the IS-3. Only a prototype was built in the 1950s before the project was cancelled, as the Conqueror heavy tank took over the role.
