DEADLY UPGRADE for Leopard 2A4 Main Battle Tank unveiled in Germany to rival M1 abrams tank

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 primary armament for production versions of the Leopard 2 is the Rheinmetall 120 mm smoothbore gun, in either the L44 variant (found on all production Leopard 2s until the A5), or the L55 variant (as found on the Leopard 2A6 and subsequent models).[8] 27 rounds of the main gun ammunition are stored in a special magazine in the forward section of the hull, to the left of the driver's station, with an additional 15 rounds stored in the left side of the turret bustle, and separated from the fighting compartment by an electrically operated door.[8] If the ammunition storage area is hit, a blow-off panel in the turret roof would direct an explosion upwards away from the crew compartment.[8] The gun is fully stabilized, and can fire a variety of types of rounds, such as the German DM33 APFSDS-T anti-tank round, which is said to be able to penetrate 560 millimeters (22 in) of steel armour at a range of 2,000 metres (2,200 yd),[11] and the German DM12 multipurpose anti-tank projectile (MPAT).[12] For the L55 gun, a newer APFSDS-T round was introduced to take advantage of the longer barrel, the DM-53, which is said to be able to penetrate in excess of 810 mm of RHAe armour at a range of 2,000 meters.[8] The bore evacuator and the gun's thermal sleeve of the A4 and A5, designed to regulate the temperature of the barrel, are fabricated out of glass-reinforced plastic. The barrel has a chrome lining to increase barrel life.[13] The main gun is capable of power elevating from +20° to −9°.[14]

Rheinmetall has developed an upgrade for Leopard 2 tanks to give them the ability to fire the LAHAT anti-tank guided missile through the main gun; the missile can engage targets out to a range of 6,000 metres (20,000 ft).[15]
Germany (Listeni/ˈdʒɜrməni/; German: Deutschland), officially the Federal Republic of Germany (German: Bundesrepublik Deutschland, pronounced [ˈbʊndəsʁepuˌbliːk ˈdɔʏtʃlant] ( listen)),[11] is a federal parliamentary republic in western-central Europe. The country consists of 16 states and its capital and largest city is Berlin. Germany covers an area of 357,021 square kilometres (137,847 sq mi) and has a largely temperate seasonal climate. With 80.3 million inhabitants, it is the most populous member state in the European Union. Germany is the major economic and political power of the European continent and a historic leader in many theoretical and technical fields.

Various Germanic tribes occupied what is now northern Germany and southern Scandinavia since classical antiquity. A region named Germania was documented by the Romans before AD 100. During the Migration Period that coincided with the decline of the Roman Empire, the Germanic tribes expanded southward and established successor kingdoms throughout much of Europe. Beginning in the 10th century, German territories formed a central part of the Holy Roman Empire.[12] During the 16th century, northern German regions became the centre of the Protestant Reformation. Occupied during the Napoleonic Wars, the rise of Pan-Germanism inside the German Confederation resulted in the unification of most of the German states in 1871 into the German Empire, which was dominated by Prussia.
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 required of armoured troops on the battlefield.[1]
