M1A2 Abrams

The M1 Abrams is a principle combat tank of the U.S. Army, and is set to be featured in Call of Duty 4: Modern Warfare.

However, its large size makes it sometimes cumbersome in urban warfare, and at least one M1 Abrams tank became stuck in close quarters when the U.S. armed forces deployed to the Middle East in the events of Call of Duty 4.
