In 2947, Aldis Industries received a commission to produce a super-heavy tank for House Davion. Their assignment was to forego maneuverability and speed in the interests of heavy armor and massive firepower. Five years later, Aldis released the 100-ton Behemoth Heavy Tank.
         The design served House Davion well through the end of the Succession Wars and the Clan Invasion, and was licensed to New Samarkand Metals as a sign of the Fox's cooperation with the Dragon. They built an upgraded version of the design until the Jihad began and the Combine needed to hoard what remained of its recovered Star League technology for its BattleMechs. Coordinator Kurita ordered a refit of the vehicle, and the Behemoth K2 was born.

         Two SarLon MaxiCannons give the Behemoth heavy firepower with long range. Using these weapons, a hit scored against other battlefield vehicles will almost guarantee a kill. These two are extremely deadly, even against many 'Mechs.
         The LongFire Light Missile Racks give the Behemoth added long-range hitting capability. To allow the Behemoth to withstand extensive damage, the design uses two smaller missile racks, rather than a larger rack. One lucky hit might take out a single rack, but it would take two lucky hits to disable all of them. As the racks are mounted facing forward on the backof the tank, they can fire over small hills without exposing the tank to enemy fire.
         The two Shigunga SRM 6s and two MRM 10s are time-proven weapons used on many vehicles. They were added to the Behemoth's arsenal to provide extra firepower, as shorter ranged missiles provide the best killing-power against vehicles.
         The four Sperry Browning MiniGuns are an afterthought, mounted around the Behemoth, which gives the weapons wide arcs of fire.
         The Behemoth's twelve tons of Star Slab Glaze laser-reflective armor is equal to that mounted by some of the most powerful 'Mechs, and can withstand almost any attack. The armor is built in plated sections, for easier removal and repair.
         The tank's main drawback is its slow speed. Because its maximum speed is only 32 kph, the Behemoth might not be able to regroup or retreat at crucial moments, and could end up being overrun in a prolonged battle.

         While standard Behemoths are a common sight throughout the Federation Expanse, the K2 is only seen in the Draconis Rifts. Deployed throughout old-Combine space during the Jihad, many were left behind when central control of the outer regions failed. As such, they can be seen throughout the region of space, though few are used beyond it.
