The United States military has also utilized heavy duty conventional main battle tanks. The heavy tank is a behemoth which employs a pair of tracked chassis using the poorly-chosen leaf spring suspension, with a single turret mounted on the top. Its key advantage is firepower: The heavy tank is equipped with a pair of large-caliber 140mm cannons using conventional ammunition. All together, the tank weighed over sixty tons, making it unusable in marshlands and other soft terrains, despite the reliability that allowed for a single soldier to hotwire them and restore them to working order.
