Desecrator
A Bacterian Desecrator is a massive cybernetic beast of war, mounted upon four massive spine-legs. Each Desecrator is roughly tank-sized, and both extremely violent in its actions and indiscriminate with who bears the brunt of its wrath. Whether using its massive Battle Cannon to destroy entire formations or ripping apart enemies with its massive claws, this engine of war acts as a harbinger of utter devastation to its foes.
The Bacterian scientists who created these nightmarish constructions originally devised them to serve as walking artillery pieces, though their Drivers' obsession with destruction soon saw these twisted creations becoming ever more bestial and aggressive.
Driver
Unlike the main battle tanks of the United Orcs, the Desecrator is not operated by a crew, but by a biomechanical creature bound within its metallic shell. Enraged by its imprisonment, the organism needs to be sedated by chemicals which are only lifted when battle begins. With its full anger at its imprisonment unleashed, the Driver moves the Desecrator forward on its four legs, spewing death from its implanted weaponry.
It rejoices in battle, ripping apart the enemy with its great claws while emitting terrible roars of rage and delirious battle-joy. Unconcerned for its survival, the Desecrator's Driver ignores the blasts of missiles and detonations of artillery against its armoured body, advancing through the heaviest weapons fire without hesitation.
Tactical role
Over time, the multi-legged chassis that bears the Desecrator has been adapted to include shearing claws and spiked armour plates. The crab-like body supports a torso that carries an array of deadly weaponry, ranging from Autocannons to racks of highly explosive missiles. It is the Battle Cannon mounted in its chest turret, however, that is undoubtedly its most potent armament.
Those foes fortunate enough to survive a Desecrator's barrage of shells must then face its full fury at close quarters. Built with piston-driven claws to grab and crush the enemy and boasting whirring blades or whip-like flails mounted on articulated limbs, the Desecrator charges into the foe, crushing and grinding as it smashes aside all opposition. Its mechanical growls drown out the cries of the wounded and dying; trampled corpses and mutilated limbs are left scattered in a red path behind it as the biomechanical machine rampages through the enemy's ranks.
