Liberator Class Titan technical briefing:
A prime example of the inferior tech-heresies produced by the Chaos forces of Slawkenberg, the Liberator is a poorly built heap of rusted metal and inferior xeno-tech that is no match for even a humble Leman Russ.
While Imperial commanders have understandably balked at the knowledge that Cainite forces are capable of deploying hundreds of titan-sized vehicles, one has only to stop and realize that the sheer number of these traitor warmachines betrays their lack of military value. Shoddily constructed of lightweight materials rather than emperor-blessed Adamantium, the Liberator relies on void shields that are pitifully weak when compared to a Gloriana class Batlleship^1.
As further evidence of the pitiful capabilities of this warmachine, it is optimized for speed, stealth, and long range range combat. Only a supremely cowardly enemy would devise a weapon that is good at running away from the enemy.
Cainite inferiority compared to the blessed creations of the Mechanicus is only further affirmed by the integration of Xenos technology into the walking scrapheaps. Featuring Drukhari shadowfields and what appears to be Ork Shokk Atttack Gun technology, the Liberator is abominable as it is laughably ineffective.
If faced with a Liberator in battle, Imperial forces should simply fix bayonets and engage the enemy in melee^2 where the cowardly soldiers of the USA will be helpless. Fleeing from such an ineffective weapon is grounds for immediate execution, for only a great moral failing can prevent the righteous Imperial guard from overcoming so weak a foe.
1. Comparisons to the void shields of Imperial titans are unnecessary and heretical by order of Inquisitor al Albert
2. Drive the tanks closer so the crew can hit them with swords.
