The British Army recently showed off a new concept for a Challenger 2 main battle tank optimized for urban operations, dubbed Streetfighter II. The vehicle has an Israeli-made IronVision distributed vision system, which allows the crew to see in all directions even while riding inside with all the hatches closed and a mock-up of a launcher for the increasingly popular Brimstone anti-tank missile on top of the turret.
Elements of the Royal Tank Regiment evaluated the Streetfighter II tank during exercises at Copehill Down earlier in January 2020. Copehill Down is one of the facilities within the U.K. Ministry of Defense's expansive training area on Salisbury Plain and is set up to simulate what British forces refer to as Fighting In Built Up Areas, or FIBUA. In the United States, this is more commonly known as Military Operations in Urban Terrain, or MOUT. The British Army first began the Streetfighter project in December 2018
