M-26 in Korea

M-26 took part in WW2, but at the late stage. The most his presence took place in Korea. In spite it was a good tank, he had a serious issues.
Here's part of the text from "Osprey: T-34-85 vs M26 PERSHING, Korea 1950".

The opinion of US tankers about the various types of US tanks changed in 1951 once the T-34-85 threat disappeared. The M26 Pershing was undoubtedly the most sought-after type in 1950, when the tank fighting was still intense. But once the tank fighting declined after 1950, the M26 was shunned due to its automotive shortcomings, particularly its sluggish performance on hills and its sloppy transmission. Those tankers with experience in the M4A3E8 preferred it over the M26, since it was more reliable, easier to maintain, and far more nimble to drive. Its automotive performance in the hilly Korean countryside was far superior to that of the M26, and its firepower was perfectly adequate against the now rarely encountered T-34-85. The M46 cured many of the problems encountered with the M26 due to the introduction of a new engine and cross-drive transmission, and so was preferred over the M26.

M-26 vs T-34/85 is an interesting match up, for a SF mission. And I have some info about these early engagements that I will get back with. 1950 Korea US forces were trying to fight the battle with the M24 Chaffee which was hopelessly battling the T-34/85's in a loosing battle. Not until the aged Sherman and the M-26 came into the battlefield did the United Nations Command have a match for the T-34/85's.

The M4A3E8 Sherman and T-34-85 were comparable and could destroy each other when hit, although the use of High Velocity Armor Piercing shells gave the Sherman a firepower advantage.
