Tank

German Tiger tank.

A tank is a tracked, armoured fighting vehicle designed for front-line combat and combines strong strategic 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.

Tanks were first manufactured during World War I in an effort to break the bloody deadlock of trench warfare. The British Army was the first to field a vehicle that combined three key characteristics: mobility over barbed wire and rough terrain, armour to withstand small arms fire and shrapnel and the firepower required to suppress or destroy machine gun nests and pillboxes. Despite some success and a significant psychological effect on the German infantry, "the tank in 1918 was not a war-winning weapon."

Interwar developments culminated in the blitzkrieg employed by the German Wehrmacht during World War II and the contribution of the panzers to this doctrine. Hard lessons learned by the Allies during WWII cemented the reputation of the tank, appropriately employed in combined arms forces, as "indispensable to success in both tactical and strategic terms." Today, tanks seldom operate alone, being organized into armoured units and operating in combined-arms formations. Despite their apparent invulnerability, without support tanks are vulnerable to anti-tank artillery, helicopters and aircraft, enemy tanks, anti-tank and improvised mines, and (at close range or in urban environments) infantry.

Due to its formidable capabilities and versatility the battle tank is generally considered a key component of modern armies, but recent thinking has challenged the need for such powerful and expensive weaponry in a period characterized by unconventional and asymmetric warfare. Ongoing research and development attempts to equip the tank to meet the challenges of the 21st century... (more)

The AMX-30E (E stands for España, Spanish for Spain) was a main battle tank, based on the French AMX-30. Although originally the Spanish government sought to procure the German Leopard 1, the AMX-30 was ultimately awarded the contract due to its cheaper price and the ability to manufacture it in Spain. It was manufactured by Santa Bárbara Sistemas for the Spanish Army, between 1974 and 1983. First acquired in 1970, the tank was to supplement Spain's fleet of M47 and M48 Patton United States tanks and to reduce Spain's reliance on American equipment in its army. The first 19 AMX-30 tanks were acquired from France in 1970, while another 180 were assembled in Spain. It was Spain's first mass produced tank and developed the country's industry to the point where the government felt it could produce a tank on its own, leading to the development of the Lince tank project in 1985. It also offered Santa Bárbara Sistemas the experience which led to the production of the Leopard 2E in late 2003. Although final assembly was carried out by Santa Bárbara Sistemas, the production of the AMX-30E also included other companies in the country. Total production within Spain amounted to as much as 65% of the tank. Spain's AMX-30E fleet went through two separate modifications in the late 1980s, a modernization program and a reconstruction program. The former, named the AMX-30EM2 (150 tanks), sought to modernize and improve the vehicle's automotive characteristics, while the latter, or the AMX-30EM1 (149 tanks), resulted in a more austere improvement of the tank's power plant by maintaining the existing engine and replacing the transmission. Both programs extended the vehicle's lifetime. Spain's fleet of AMX-30EM1s was replaced in the late 1990s by the German Leopard 2A4, and the AMX-30EM2s were replaced by Centauro wheeled anti-tank vehicles in the early 21st century. Although 19 AMX-30Es were deployed to the Spanish Sahara in 1970, the tank never saw combat. In 1985 Indonesia expressed interest in the AMX-30E, while in 2004 the Spanish and Colombian governments discussed the possible sale of around 40 AMX-30EM2s. Both trade deals fell through.

Featured battle

The Battle of Arras was a British offensive during World War I. From 9 April to 16 May, 1917, British, Canadian, and Australian troops attacked German trenches near the French city of Arras on the Western Front. For much of the war, the opposing armies on the Western Front were at a stalemate, with a continuous line of trenches stretching from the Belgian coast to the Swiss border. In essence, the Allied objective from early 1915 was to break through the German defences into the open ground beyond and engage the numerically inferior German army in a war of movement. The Arras offensive was conceived as part of a plan to bring about this result. It was planned in conjunction with the French High Command, who were simultaneously embarking on a massive attack (the Nivelle Offensive) about eighty kilometres to the south. The stated aim of this combined operation was to end the war in forty-eight hours. At Arras, the British Empire's immediate objectives were more modest: (1) to draw German troops away from the ground chosen for the French attack and (2) to take the German-held high ground that dominated the plain of Douai. Initial efforts centred on a relatively broad-based assault between Vimy in the northwest and Bullecourt in the southeast. After considerable bombardment, Canadian troops advancing in the north were able to capture the strategically significant Vimy Ridge, and British divisions in the centre were also able to make significant gains. Only in the south, where British and Australian forces were frustrated by the elastic defence, were the attackers held to minimal gains. Following these initial successes, British forces engaged in a series of small-scale operations to consolidate the newly won positions. Although these battles were generally successful in achieving limited aims, many of them resulted in relatively large numbers of casualties. When the battle officially ended on 16 May, British Empire troops had made significant advances, but had been unable to achieve a major breakthrough at any point. Experimental tactics—for instance, the creeping barrage, the graze fuze, and counter-battery fire—had been battle-tested, particularly in the first phase, and had demonstrated that set-piece assaults against heavily fortified positions could be successful. This sector then reverted to the stalemate that typified most of the war on the Western Front... (more)
