The Mobile Land Mine (originally named "Beetle") was an experimental British World War II remote-controlled tracked explosive device. It was wire guided and powered by two electric motors. The Mobile Land Mine was designed by Metropolitan-Vickers in 1940. After a successful demonstration in August 1941 an order for 50 was placed so that trials could be carried out. In 1942 Commander-in-Chief, Home Forces reported that it was not recommended as there was no requirement for it. It was underpowered, slow, the motors overheated and it couldn't cross typical battlefield terrain - it was finally rejected by the General Staff in 1944. Among other trials a Mobile Land Mine was waterproofed and equipped with floats allowing it to be used against landing craft.
