During 1953, a few M-41s were sent to Korea for combat evaluation, but these saw only limited patrol action in the last days of the war. During its service life with the US Army, M41s didn't see any significant action. Too late for Korea and replaced by the M551 Sheridan by the time US commited ground troops to Vietnam. That being said, M41 platform spawned a number of variants like M42 AA configuration, M75 APC, and M44 SPG. M41 did enjoy a long service life with a great number of foreign nations. Brazil and Denmark modernized M41 to the point that it barely resembled the original.
