More heavy tank moves have occurred over the last week. Here the T29E3 departs the line at the Fort Benning Logistics Readiness Center for our new home.

The E3 variant featured a coincidental range finder mounted in armored 'ears' on the sides of the turret. | The U.S. Army Armor & Cavalry Collection
