The US. Army withdraws all M-1128 MGS Cannons
Deliveries began in 2002 and were completed in 2010. The service said in a news release that the 105 mm calibre cannon no longer meets the Army's operational requirements. The automatic loader has systemic issues.
The M-1128 was the first US Army vehicle to be equipped with an autoloader, a major innovation. However, now the cost of supporting the system has increased significantly.
This Stryker model is an eight-wheeled infantry support vehicle with a 105mm tank gun, based on Canada's LAV III armoured vehicle. The Army developed it in the early 2000s.The main mission of the M-1128 is to provide support fire to Battalion level units (2-3 per Battalion in the US Army). It is not designed to engage tanks, especially with a 120 mm cannon. The Army said this Stryker model was developed with a flat-bottom chassis and was never upgraded to deal with improvised explosive devices or anti-tank mines. It is designed to support the Infantry in battle. The maximum firing rate is ten rounds per minute. It can use four types of ammunition: M-900 (kinetic energy), M-456A2 (high explosive), M-393A3 (high explosive crushed warhead) and M-1040 (anti-personnel).
