The Omnicrine was the largest tank ever designed by humanity. Not much is known about this tank. It only existed on blueprints and never was actually built and money went into the construction of the Infinity Class Warship instead. Its size was comparable to the Covenant "High Charity" holy city. The basic model of the machine was based off the 1945 prototype T95 Super Heavy Tank, only scaled up thousands of times larger. The closest sized tank ever designed was the Nazi's Landkreuzer P.2000 Gott. Even the Gott was outmatched by the Omnicrine's size.
