Tall, squat, and using four treads, the Demolisher has a well-earned, though sometimes exaggerated, reputation as one of the most deadly vehicles on the battlefield. Designed to counteract the increasing scarcity of 'Mechs during the Succession Wars, the Demolisher became popular, especially on worlds where BattleMechs were not available.

Aldis designed the Demolisher to be able to destroy any 'Mech, which was what appealed to the customers. The initial run was well-received, with hundreds of Demolishers being bought by 'Mech-deficient planets.

Weapons and Equipment[edit]

The Demolisher is armed with two 185mm ChemJet Gun Autocannon/20s, which are enough to make any other unit, 'Mechs included, pause. The relatively short range of the guns means that maneuverable units with long-range weaponry can confound the Demolisher. It utilizes 10 tons of armor for protection, and the internal combustion engine allows for a cruising speed 32.4 km/h. The tank also lacks any form of secondary weapons, which may be detrimental when the massive cannons run dry.


Some crews are known to remove armor and install small defensive weapons if the situation requires.

  • Devastator Heavy Tank 
    The third generation of the Demolisher, the DVE-5B Mark III, was found mainly among the defense forces of the richer planets in the Inner Sphere. It is powered by a Type 240 fusion engine and mounts some additional weapons: A Zippo Flamer in the turret, one Intek Small Laser in the front and on each side, and a front-mounted Holly SRM-6.[3] BV (2.0) = 1,029[4]
  • Arrow IV 
    This Advanced version of the Demolisher tank debuted during the FedCom Civil War. It replaces the AC/20's and some armor with a pair of Arrow IV missile launchers and seven tons of ammunition. For defense against close range attacks it mounts a pair of medium lasers. BV (1.0) = 676[5], BV (2.0) = 1,297[6]
  • Clan 
    Developed by the Clans in 3058, this variant carries twin LB 20-X ACs as its main armament and with 40 salvos can deliver a lot of damage to its enemies. Mounted coaxially with these huge autocannon are a pair of Medium Pulse Lasers. Six Machine Guns scattered across the front and side arcs protect it from infantry. Like most Clan vehicles, the Clan Demolisher carries CASE to protect the ammunition bay. BV (1.0) = 1,184[7], BV (2.0) = 1,563[8]
  • Gauss 
    This 3053 version of the Demolisher swaps the AC/20's for twin Gauss rifles with 4 tons of ammunition and a pair of medium lasers. It also adds some armor protection. BV (1.0) = 1,090 [9], BV (2.0) = 1,529[10]
  • MRM 
    Developed during the late Clan Invasion-era, this variant can launch almost one hundred missiles at an enemy thanks to its three MRM-30 launchers.Each launcher can count on 2 tons of ammunition. A C3 slave allows it to take advantage of targeting data provided by other units. BV (1.0) = 1,006 [11], BV (2.0) = 1,242[12]

  • In German products, the unit's proper name was translated to Zerstörer, which literally means Destroyer.
  • Grayson Carlyle, in The Price of Glory, takes note of multiple Demolishers in a Star League-era cache discovered on Helm. As the Demolisher was introduced after the Star League's fall, Carlyle was likely mistaken in his identification of the tank.[13]
