The Warlord Battle Titan is a class of Imperial Battle Titan. It is the most numerous of Imperial Titans with millions having been built over the many years of its existence; in fact the design is older than the Imperium of Man itself. The Warlord is essentially a walking fortress, packing enough firepower to wipe out entire armies on its own. The only true threat to a Warlord is another Titan of the same magnitude, such as those used by the traitorous Dark Mechanicus or the alien Ork and Eldar races. Thousands of Warlord Titans saw action on both sides during the wars of the Horus Heresy.
The Warlord is by far the most widely employed, numerous and versatile class of Imperial Battle Titan deployed by the Collegia Titanica; it is second in power only to the rare Emperor Class Titans. Some Warlords date back to time of the Great Crusade or even the Dark Age of Technology.
The sheer longevity of the Warlord means a variety of different patterns and variants have been built, some mounting unusual upgrades such as landing platforms for aircraft, siege rams to batter down walls and assault pods to disgorge infantry into the enemy’s strongholds. This also means the design’s capabilities and tolerances are well-known among the Mechanicus, making the Warlord an ideal test-bed for new devices conjured up by the Divisio Investigatus.
The primary role of a Warlord is as front-line combatant where the fighting is heaviest. Its primary line of defense are six Void Shield generators which intercept enemy fire before it even hits the war engine. So powerful are these shields that a Warlord can withstand continuous bombardment from over five dozen armored vehicle and artillery platforms with no loss of shield strength. Beneath the shields are meters of adamantium armored plating, which themselves can ward off a regiment‘s worth of firepower with but minor scarring. The weaponry the Warlord mounts is similarly stupendous, with four primary Titan-grade systems and numerous secondary armaments for fighting in built-up areas. So powerful are these weapons that Warlords can level entire cities with them.
A Warlord can easily destroy a Warhound Scout Titan in a matter of seconds, and will handily defeat a Reaver Battle Titan in a one-on-one duel. Warlord Battle Titans do have one weakness in that their plasma reactor is located in the abdominal cavity, making it susceptible to heavy weapons fire if the armor is breached. For this reason many Warlords are geared towards long-range fire support.
