In 2074, the Combine was flush with the success of the largest cybertank to date, the Ogre Mk. III. Designers were tasked with building a bigger, better Ogre. Rather than build one unit to do everything, they designed two: the Mk. V for short-range, high-intensity exchanges, and the Mk. IV for fast strike, long-range power.
The Ogre Mk. IV carries a single main gun, and a pair of secondaries. However, its primary weapons are the three missile racks mounted in the rear, loaded with 5 missiles each. In addition, it moves faster than any other unit, short of a GEV . A certain amount of durability was sacrificed to achieve such speeds though; this cybertank has only 56 tread units.
