The Leopard 2 is a main battle tank developed by Krauss-Maffei in the early 1970s for the West German Army. The tank first entered service in 1979 and succeeded the earlier Leopard 1 as the main battle tank of the German Army. Various versions have served in the armed forces of Germany and twelve other European countries, as well as several non-European nations. More than 3,480 Leopard 2s have been manufactured. The Leopard 2 first saw combat in Kosovo with the German Army and has also seen action in Afghanistan with the Danish and Canadian contributions to the International Security Assistance Force. There are two main development batches of the tank, the original models up to Leopard 2A4, which have vertically faced turret armour, and the "improved" batch, namely the Leopard 2A5 and newer versions, which have angled arrow-shaped turret appliqué armour together with other improvements. All models feature digital fire control systems with laser rangefinders, a fully stabilized main gun and coaxial machine gun, and advanced night vision and sighting equipment (first vehicles used a low-light level TV system or LLLTV; thermal imaging was introduced later on). The tank has the ability to engage moving targets while moving over rough terrain. The Canadian Forces (CF) (French: les Forces canadiennes; FC), officially the Canadian Armed Forces (French: Forces armées canadiennes),[7] is the unified armed force of Canada, as constituted by the National Defence Act, which states: "The Canadian Forces are the armed forces of Her Majesty raised by Canada and consist of one Service called the Canadian Armed Forces."[7] This unified institution consists of sea, land and air elements referred to as the Royal Canadian Navy (RCN), Canadian Army, and Royal Canadian Air Force (RCAF). Personnel may belong to either the Regular Force, Primary Reserve, Supplementary Reserve, Cadet Organizations Administration and Training Service, or the Canadian Rangers. The Department of National Defence acts as the civilian support system for the Canadian Forces.[8][9] The Canadian Forces is overseen by the Armed Forces Council, chaired by the Chief of the Defence Staff. The Commander-in-Chief is the reigning Canadian monarch, Queen Elizabeth II,[10] who is represented by the Governor General of Canada.[11] Since the Second World War, Canadian defence policy has consistently stressed three overarching objectives: The defence of Canada itself; The defence of North America in cooperation with US forces; Contributing to broader international security. During the Cold War, a principal focus of Canadian defence policy was contributing to the security of Europe in the face of the Soviet military threat. Toward that end, Canadian ground and air forces were based in Europe from the early 1950s until the early 1990s. A tank is a tracked, armoured fighting vehicle designed for front-line combat which combines operational mobility and tactical offensive and defensive capabilities. Firepower is normally provided by a large-calibre main gun in a rotating turret and secondary machine guns, while heavy armour and all-terrain mobility provide protection for the tank and its crew, allowing it to perform all primary tasks of the armoured troops on the battlefield.[1] Tanks in World War I were developed separately and simultaneously by Great Britain and France as a means to break the deadlock of trench warfare on the Western Front. Their first use in combat was by the British Army on September 15, 1916 at Flers-Courcelette, during the Battle of the Somme. The name "tank" was adopted by the British during the early stages of their development, as a security measure to conceal their purpose (see etymology). While the French and British built thousands of tanks between them, Germany developed and brought into service only a single design, the A7V, producing 20 vehicles due to lack of capacities or resources. Tanks of the interwar period evolved into the designs of World War II. Important concepts of armoured warfare were developed; the Soviet Union launched the first mass tank/air attack at Khalkhin Gol (Nomonhan) in August 1939,[2] which later resulted in the T-34, a predecessor of the main battle tank; this was quickly followed up by Germany on a larger scale when they introduced blitzkrieg ('lightning war') less than two weeks later; a technique which made use of massed concentrations of tanks supported by artillery and air power to break through the enemy front and cause a complete collapse in enemy resistance and morale. Canada Listeni/ˈkænədə/ is a North American country consisting of ten provinces and three territories. Located in the northern part of the continent, it extends from the Atlantic to the Pacific and northward into the Arctic Ocean. Canada is the world's second-largest country by total area, and its common border with the United States is the world's longest land border shared by the same two countries.
