[edit] History

While the Chaffee was a successful design, its main gun was not effective enough against well armored opponents. Although the primary mission of light tank was scouting, Armored Force wanted one with more powerful armament. The development of the new tank, T37, began in 1947. The vehicle was designed to be air-transportable, and the desired anti-tank capabilities were provided by installing a long 76 mm gun with an advanced rangefinder. In 1949, with the adoption of a less ambitious rangefinder, project changed its designation to M41. Production started in 1951 at Cadillac's Cleveland Tank Plant, and by 1953 the new tank completely replaced the M24 in the US Army. Initially it was nicknamed "Little Bulldog", then renamed to "Walker Bulldog" after General Walton Walker, who was killed in a jeep accident in Korea in 1950.

The M41 was an agile and well armed vehicle. On the other hand, it was noisy, fuel-hungry and heavy enough to cause problems with air transport. In 1952 work began on lighter designs (T71, T92), but those projects came to naught and were eventually abandoned.

Walker Bulldog never saw combat with the US Army. But in 1965 a number of vehicles were supplied to South Vietnam. The M41 went on to form the bulk of the ARVN Armored Force, and played a significant role in the Vietnam War. Being too lightly armored for most battlefield tasks, the tank was used mostly for internal security missions. On several occasions when the tank encountered North Vietnamese armor its gun was reportedly effective against enemy tanks including T-54.

The M41 has been also exported to Brazil (300), Chile (60), Dominican Republic (12), Guatemala (10), Somalia (10), Taiwan (675), Thailand (200), Tunisia (10) and other countries. Many of these tanks were upgraded to prolong their life. Some are still in service. Thai M41s were used in the Thailand coup d'état in September, 2006.

[edit] Legacy

The M-41 was replaced in the US Army by the advanced, but troublesome M551 Sheridan light tank which had a gun/missle which could destroy any heavy tank, could swim and was air drop capable. The chassis of the M-41 was used for the M42 Duster, which mounted two 40-mm anti-aircraft guns. It was also built up into the M75 Armored Personnel Carrier, one of the first enclosed box-shaped personnel carriers. The M75 would be the pattern for the M113 APC which would become the most widely produced US armoured combat vehicle.
