are two versions of the SCD; a V-blade optimised for clearing routes and a straight angle-blade which is optimised for clearing staging and assembly areas. Vehicle Magnetic Signature Duplicator (VEMSID): (LIN V53112) The VEMSID increases the effectiveness and survivability of countermine equipment by causing the stand-off detonation of magnetic influence mines at a safe distance ahead of the tank. It generates a multi-axial magnetic signature optimized for passively fused magnetic influence fused mines. The system comprises four emitter coils, two associated power boxes and an MSD Control Unit (MSDCU). Air Ground Defense System (AGDS): Proposed air defense variant of the Abrams equipped with dual 35 mm Bushmaster III autocannons, 12 ADATS missiles and advanced electro-optical and radar targeting systems derived from the ADATS. It was supposed to be capable of both air defense and anti-tank purposes with the ADATS MIM-146 missiles which was a dual purpose ATGM/SAM. The proposal never saw consideration and was never developed further. Specifications Operators – Australian Army: 59 M1A1 (AIM) configuration tanks (hybrids with a mix of equipment used by U.S. Army and U.S. Marine Corps but without depleted uranium layers in armor). These tanks were bought from the U.S. in 2006 and replaced the Leopard AS1 in 2007. As of 2017, the Australian Government was considering expanding the Army's fleet of Abrams to 90 tanks. In April 2021, the U.S. granted an FMS for 160 M1A1 tank hulls to produce 75 M1A2 SEPv3 Abrams Main Battle Tanks, 29 M1150 Assault Breacher Vehicles and 18 M1074 Joint Assault Bridges including the development of a unique armor package for the Australian Army. In January 2022, Australia committed to purchase 120 tanks and armored vehicles including 75 M1A2s at a total cost of $3.5 billion and to be delivered in 2024; the M1A2s are to replace their 59 M1A1s which were bought in 2007. – Egyptian Army: 1,360 M1A1 tanks assembled in Egypt for the Egyptian Army in cooperation with the U.S. – Iraqi Army: 321 M1A1Ms Iraq was leasing 22 U.S. Army M1A1s for training in 2008. The first 11 tanks were delivered to the Iraqi Army in August 2010 with all deliveries completed by August 2011. In October 2012, it was reported that six more tanks were being delivered. Zaloga wrote that four battalions of the 9th Armoured Division were equipped with M1s by 2014: 1st and 2nd of the 34th Brigade, and 4th and
