Introduced in 2952, the Behemoth was designed for increased firepower and heavy armor rather than speed or maneuverability. The design allowed the Behemoth to engage both distant and short-range targets, while allowing it to stand up to almost any type of unit possible.[3][4][5]

Weapons and Equipment[edit]

The two turret-mounted SarLon MaxiCannon AC-10s enable the Behemoth to deal out a great deal of damage at a long distance. The four front-mounted LongFire Light Missile Racks increase this damage potential, particularly in the forward arc of fire. For closer targets, two Harvester 20K SRM-6 packs are mounted on the turret and the Behemoth boasts two ball turrets, each mounting one Harvester 2K SRM-2 and two MainFire MiniGuns. The final two Harvester 2K SRM-2 packs are mounted in a half-turret on the front of tank.[3][4][5]


  • Davion 
    This variant was built by GM in the 3080s for sale to the Federated Suns and was itself based on the older fusion powered upgrade. Total armor protection is only slightly increased, though the use of Heavy Ferro-Fibrous armor allows weight savings of over 2 tons. While visually very similar to the original, almost the entirety of the weapons loadout is replaced, with only the SRM-2s remaining. The ACs have been replaced with a pair of Gauss Rifles. The turret mounted SRM-6s have both been upgraded to Streak launchers with the same tube count. The two forward hull mounted machine guns have been replaced with a pair of ER Medium Lasers. The sides of the tank each still carry the SRM-2 and a Magshot replaces the original Machine Guns. Both of these weapons are now carried in a sponson allowing excellent firing arcs and allows for at least one Magshot to fire at infantry coming from any direction. Finally the quartet of LRM-5s have been replaced with a pair of Rocket launcher 10s. CASE protects the crew. BV (2.0) = 1,662[7]
  • Flamer 
    The 2981 variant is not a factory model, but, rather, individual modifications where crews have replaced the SRM-2 missile packs with Flamers.[4] BV (1.0) = 709[2][5]
  • Kurita 
    Developed in 3062 during the FedCom Civil War and produced by New Samarkand Metals, this version of the Behemoth removes all the standard weaponry. It carries a pair of Ultra AC/10s, a pair of MRM-10 launchers, and a pair of Artemis IV FCS enhanced SRM-6 launchers in the turret. To provide some additional long range firepower, it mounts a pair of LRM-5 launchers with Artemis guidance systems on the front of its hull. BV (2.0) = 1,336[8]
  • Liao 
    This variant of the Behemoth came about due to lack of parts to produce the newer Behemoth II Heavy Tank. Aldis Industries took traditional Behemoth hulls and mated the to Behemoth II turret assemblies and revised the weapons compliment. The Behemoth II’s single Gauss Rifle remains in place as do the quartet of Rocket Launcher 10s in the turret. The Thunderbolt launchers have been replaced with a pair of MML-5s in the turret. Four additional MML-5s replace the original Behemoth’s LRM-5s in the front hull and sit below the remaining pair of Machine Guns. Both sides of the tank also feature a single MML-5 in a sponson. In total, this Behemoth has 40 Multi-Missile tubes it can fire forward and can even fire 15 to each side arc. This variant still uses the original variant’s internal combustion engine and armor, though CASE now protects the crew. Unlike the Behemoth II, this Behemoth is even more deadly up close then it is at range. BV (2.0) = 1,271[7]
  • Refit 
    This simple update to the classic variant replaces the traditional AC/10s with LBX-10s and adds case to the vehicle’s vast ammunition stores. BV (2.0) = 1,226[7]
