Royal Enfield Ordnance 25mm Cockerill Assault Cannon

Royal Enfield Ordnance 25mm Cockerill Assault Cannon is the first in a new range of anti-light vehicle weapons designed to complement/replace the LAW 80 and the Carl Gustav. The Cockerill cannon is a slightly scaled-down version of the 30mm weapon used in the Scimitar armored vehicle. To offset the immense potential recoil, the Cockerill uses low-pressure, rocket-assisted rounds. The round is fired by a reduced charge. When it travels 2m from the muzzle, the rocket motor ignites, boosting it to just over 800m/s (2623fps). Because of the firing system it is possible to fire the cannon from the hip-although it is not recommended (WA drops to -1). Only people with sufficient size (BOD of 8+l can do so; others must use the bipod. It requires a minimum BOD of 6 to carry and use this weapon due to its size and weight (encumbrance value +2). Rounds for this weapon include AP (armor-piercing; Pen 5), HEP (cratering; Pen 6), and APF (Anti-Personnel Flechette). Against personnel HEP does 1 /2 real, 112 stun; armor is no effect and loses 2 SP. The APF round is treated as a shotgun round with a max range of 1 OOm. The pattern starts 2m in front of the muzzle; sizes are 1 m/close, 2m/medium, and 4m/long range. Anyone in the pattern takes 1D6+3 hits; each hit does 1D6+1 AP.
