Soul Grinders

Soul Grinders are massive daemon engines, used by the Chaos Daemons as their rough analogue to a main battle tank. A daemon engine is a diabolic fusion of daemon and war machine fuelled by dark malevolence and it's own irrepressible desire to destroy. It's upper torso is composed of a large daemon of unspecified origin, while the lower torso takes the form of a crab-like machine.

They are capable of withstanding immense levels of punishment, their thick hulls further protected by the supernatural energies of the warp. Only the most potent of anti-tank weaponry is capable of doing any real harm to them. Being demonic in nature they're even capable of appearing out of thin air where they're least expected, such as in the middle of an enemy line with little to no warning.

These foul creations are nigh-unstoppable, capable of ripping apart xenos monstrosities with ease and crushing the battle tanks of other races like they were made of rotten wood.
 * Iron Claw These are massive, piston-driven claws that are capable of crushing tanks with ease and rip through even the toughest of armor. With one fell sweep it can turn entire squads of infantry into a bloody pulp. 
 * Warpsword These are massive ever-shifting daemon blades made out of pure warp energy that is capable of ripping apart infantry and vehicles alike with contemptuous ease. Worse yet there is no known material that has been able to withstand the strikes of this dreaded blade. 
 * Harvester Cannon A large, multi-barreled, rapid-firing weapon that fires large calibre solid shells capable of tearing through infantry formations and destroying light vehicles with ease. It can alternatively also fire specialized flakk shells to engage enemy aircraft with acceptable accuracy. These cannons are typically wrist-mounted on the daemon's arms and can supposedly never run out of ammunition. 
 * Bale Gaze Some Soul Grinders have developed the ability to fire powerful bolts of pure warp energy from their eyes, vaporizing infantry and turning vehicles inside-out. 
 * Searing Tongue A few Soul Grinders have also been documented to be able to use their whip-like tongues to lash out like searing energy rays,  likely capable of cutting through vast swathes of the enemy. 
 * Soul Grinder Mawcannon Soul Grinders have been able to use their mouths to spit out huge torrents of burning warpfire not too dissimilar to a huge flamethrower, incinerating affected enemies.
