The Rarden (L21A1) is a British long-recoil automatic, aimed, single-shot cannon designed during the 1960's for the destruction of APCs at a range of 1000 meters, the penetration of main battle tankarmour from the side, the destruction of soft targets and as a deterrent against low flying slow aircraft and helicopters with accuracy as the prime consideration. The Rarden is chambered for a 30 mm cartridge which it takes from a 3-round clip and fires at a rate of about 90 rounds per minute. Rarden was mounted on the Scimitar tracked reconnaissance vehicle during the 1970's. Research Rarden
