Background: Replacing the Sheridan
Following the end of the Cold War some theorists believed that the existing suite of U.S. armored vehicles, designed largely to fight Soviet mechanized forces in Europe, were not well suited to the lower-intensity missions U.S. military would be tasked with.[citation needed] This led to the development of a new armored fighting vehicle designed for lower-intensity combat, rather than large-scale battle. By 1992, the Armored Gun System emerged as a top priority procurement program for the Army...
Interim Armored Vehicle competition
The General Dynamics Mobile Gun System originated from the Canadian Armoured Combat Vehicle requirement. In partnership with General Motors, General Dynamics Land Systems (GDLS)–Canada integrated its Low Profile Turret (LPT) onto a LAV III in January 1999. The turret was an updated version of the one used on the GD–Teledyne Expeditionary Tank, which was entered into the Armored Gun Systemcompetition in the 1980s. In October 1999, U.S. Army Chief of Staff Eric Shinseki laid out his vision for...
Further development and initial production
Soon after the contract was awarded, the MGS IOC date slipped two years from December 2001 to November 2003. The Army allowed GM–GDLS to substitute the Stryker ATGM variantfor the MGS in the interim. In its protest, UDLP alleged that the Army had known about the schedule slippage before awarding the contract, and unfairly disregarded this in their decision making. GDLS delivered the first of eight pre-production Mobile Gun Systems in July 2002. In March 2004, the Army approved the transfer of...
Armor and protection
The MGS has integral all-around armor protection against 14.5 mm AProunds. The MGS commander and gunner are located in the turret basket, which provides the crew some separation from the ammunition in the event of an explosion. According to a Government Accounting Office report released in May 2001, the Army had expressed doubt that this arrangement would provide "any protection from secondary explosions and fires from the main gun ammunition."
Firepower
The MGS's low profile turret has a small silhouette, is stabilized and mounts a 105mm M68A1E4 rifled cannon with a fume extractor and an autoloader. The vehicle is primarily outfitted to support infantry combat operations. While it could take on some of the roles of a tank, it is not primarily intended or designed to engage in combat with main battle tanks. The MGS can store 18 rounds of main gun ammunition: 8 in the autoloader's carousel and 10 in a replenisher located at the rear of the veh...
Differential attributes and failures
Because the vehicle was originally designed without air conditioning (A/C), crews were given cooling vests that circulate cooled water from outside the vehicle to the garment. Vehicle computers still overheated regularly. All MGS Stryker platforms have since been upgraded with A/C units.The large weapon station and relatively smaller hatch can make emergency exits difficult. The main cannon is separate from the crew compartment. A gun stoppage during combat can be cleared only by exiting the...
The Battle of São Mamede (Portuguese: Batalha de São Mamede, pronounced [ˈsɐ̃w mɐˈmɛðɨ]) took place on 24 June 1128 near Guimarães and is considered the seminal event for the foundation of the Kingdom of Portugal and the battle that ensured Portugal's independence.
