Function: Main battle tank (MBT).









Description: The M1A1 is an improved version of the M1 Main Battle Tank (MBT). It includes a 120mm smoothbore main gun, an NBC overpressure protection system, improved suspension and powertrain and an improved armor package. In 1988 the M1A1 design was further improved by the addition of depleted uranium (DU) to the tank's armor matrix. M1A1s assigned to the Marine Corps' tank battalions were further modified to include a Position Location Reporting System (PLRS) as well as a Deep Water Fording Kit (DWFK.) As with all tanks in the M1 line, the M1A1 utilizes a 3x-10x primary sight with both ambient light and thermal (infra red) capabilities which allow the gunner to acquire, identify and engage targets in all weather conditions and at ranges out to 2.5 miles. Furthermore, crew safety is enhanced by storing all main gun ammunition in an armored compartment with specially built "blow out" panels which will redirect explosive energy away from the crew in the event the ammunition is damaged.
