Question: The Multi-Mission Effects Vehicle and  The Air Defense Anti-Tank System where both simular in what way? 
Context: Abdul Meniem Al-Toras is the current Commander of the Egyptian Air Defense Command.  He graduated from the Air Defense college in 1972, and saw action in the Yom Kippur War.  He is the first commander-in-chief of the Egyptian Air Defense Forces who graduated from the Air Defense College and was commissioned in the Air Defense Forces as a separated military branch.  All previous commanders-in-chief were graduates of the Army academy and were commissioned in Army units, in fact many of them were commissioned in non-AD units like Armour, Artillery, Infantry, and Signals.  He held most of the notable commands in the Egyptian Air Defense.  On 14 August 2012 President Mohamed Morsi Appointed him as the new Commander in Chief of the Egyptian Air Defence command after he dismissed Lt. General Abd El Aziz Seif-Eldeen.  He is a member of the Supreme Council of the Armed Forces, which was reorganized in September 2012. The Air Defense Anti-Tank System (ADATS) is a dual-purpose short range surface-to-air and anti-tank missile system based on the M113A2 vehicle.  It is manufactured by the Swiss company Oerlikon-Contraves, a member of the Rheinmetall Defence Group of Germany.  The ADATS missile is a laser-guided supersonic missile with a range of 10 kilometres, with an electro-optical sensor with TV and Forward Looking Infrared (FLIR).  The carrying vehicle also has a search radar with an effective range of over 25 kilometres. Continental Air Defense Command (CONAD) was a Unified Combatant Command of the United States Department of Defense, tasked with air defense for the Continental United States.  It comprised Army, Air Force, and Navy components.  It included Army Project Nike missiles (Ajax and Hercules) anti-aircraft defenses and USAF interceptors (manned aircraft and BOMARC missiles).  The primary purpose of continental air defense during the CONAD period was to provide sufficient attack warning of a Soviet bomber air raid to ensure Strategic Air Command could launch a counterattack without being destroyed.  CONAD controlled nuclear air defense weapons such as the 10 kiloton W-40 nuclear warhead on the CIM-10B BOMARC.  The command was disestablished in 1975 and the USAF component, Aerospace Defense Command, became the executive organization for the U.S. component of the North American Air Defense Command (NORAD). The 32d or 32nd Army Air and Missile Defense Command (AAMDC) is a theater level Army air and missile defense multi-component organization with a worldwide, 72-hour deployment mission.  The 32d AAMDC commands echelon above corps (EAC) ADA brigades and other assigned forces.  Four such brigades, 11th Air Defense Artillery Brigade, 31st Air Defense Artillery Brigade, 69th Air Defense Artillery Brigade, and 108th Air Defense Artillery Brigade; by training, all stand ready to accomplish their mission of air defense against missile attack – 'anywhere, anytime' in support of the war-fighting Commander-in-Chief (CINC). The Syrian Air Defense Force (SyADF), officially the Syrian Arab Air Defense Force, is an independent command within the Syrian Armed Forces.  It has been merged into and then separated from both the Syrian Arab Army and the Syrian Arab Air Force.  The Syrian Air Defense Force controls four air defense corps, eleven air defense divisions and thirty-six air defense brigades, each with six SAM battalions.  It is equipped with 650 static S-75 Dvina, S-125 Neva/Pechora and S-200 launchers, 200 mobile 2K12 Kub and Buk launchers and over 4,000 anti-aircraft guns ranging from 23mm to 100mm in caliber.  There are also two independent 9K33 Osa SAM regiments, each with four batteries of 48 mobile SAMs. The 4732nd Air Defense Group is a discontinued United States Air Force organization.  Its last assignment was with the 64th Air Division of Air Defense Command at Goose Air Force Base, Newfoundland, Canada, where it was discontinued in 1960.  The group was formed in 1957 when ADC assumed responsibility for air defense of Newfoundland and Northern Canada from Northeast Air Command and controlled a fighter-interceptor squadron at Harmon and seven squadrons operating radars at dispersed locations.  It was discontinued when Goose Air Defense Sector assumed responsibility for air defense of Newfoundland and Northern Canada. The Multi-Mission Effects Vehicle (MMEV) was a dual-purpose short range surface-to-air and anti-tank platform intended for use by the Canadian Forces.  It was based on Air Defense Anti-Tank System (ADATS) technology, and integrated onto an 8×8 wheeled LAV III.  The MMEV project was canceled in 2007. The 4731st Air Defense Group is a discontinued United States Air Force organization.  Its last assignment was with the 64th Air Division of Air Defense Command (ADC) at Ernest Harmon Air Force Base, Newfoundland, Canada, where it was inactivated in 1960.  The group was formed in 1957 when ADC assumed responsibility for air defense of Newfoundland from Northeast Air Command and controlled a fighter-interceptor squadron at Harmon and two squadron operating radars at dispersed locations.  It was discontinued when Goose Air Defense Sector assumed responsibility for air defense of Newfoundland. The 4706th Air Defense Wing is a discontinued United States Air Force (USAF) organization.  Its last assignment was with the 37th Air Division of Air Defense Command (ADC) at O'Hare International Airport (IAP), Illinois where it was discontinued in 1956.  It was established in 1952 at O'Hare as the 4706th Defense Wing in a general reorganization of Air Defense Command (ADC), which replaced wings responsible for a base with wings responsible for a geographical area.  It assumed control of several Fighter Interceptor squadrons that had been assigned to the 142d Fighter-Interceptor Wing, an Air National Guard wing mobilized for the Korean War and the 56th Fighter-Interceptor Group.  In early 1953 it also was assigned six radar squadrons in the Midwest and its dispersed fighter squadrons combined with colocated air base squadrons into air defense groups.  The wing was redesignated as an air defense wing in 1954.  It was discontinued in 1956 and most of its units transferred to the 58th Air Division. The 4700th Air Defense Group is a discontinued United States Air Force (USAF) organization.  Its last assignment was with the 4709th Air Defense Wing at Stewart Air Force Base, New York.  It was activated in 1950 as a support unit for USAF units at Stewart.  In 1954, it assumed an operational mission and was assigned two interceptor squadrons.  The group was discontinued on 18 August 1955 and its personnel and equipment were transferred to the 329th Fighter Group (Air Defense) as part of Project Arrow, an Air Defense Command project to air defense groups with fighter units with distinguished histories from World War I or World War II.
