Although its early design and development was marred by controversy, the M1 has developed into, arguably, the best tank in the world - a formidable blend of protection, mobility, and firepower unequaled on the battlefield. Its Chobham/depleted uranium mesh armor is highly resistant to all types of munitions; its gas turbine engine, admittedly a gas guzzler, provides it with the speed and mobility of much lighter tanks; and its 120mm smoothbore Rhinemetall gun is capable of defeating the armor of any opponent it will meet on the battlefield.%n
