The principal armament of the new vehicle comprises a 200 lb guncotton charge contained within a copper shell mounted on the end of a boom. This is normally kept raised for safety reasons until prior to making an attack, whereupon the boom is lowered to the horizontal position. The vehicle's gallant crew of driver, commander/weapon operator and two stokers then drive at speed toward an enemy landship with the intention of ramming the charge into its flanks. Detonation is normally achieved through an impact fuse on the nose of the charge. An optional cord-actuated detonator is provided should the fuse fail, or for assault demolition use against strongpoints.
The vehicle's builders provide a storage case mounted on the rear of the vehicle for a spare bomb, giving the crew the means to re-arm in some safe spot and return to battle. This of course assumes they survive the attack. A machine gun is mounted in the glacis plate for anti-personnel use.
