During the [[Korean War]], the M4A3E8 ''Easy Eight'' was the main tank force of the U.S. military until the signing of the armistice agreement.

At the outbreak of the war, the U.S. military tried to deploy the M4A3E8, a medium-sized tank of the same class, to respond to North Korean T-34-85, but there were few tanks available for rapid deployment from the Far East due to disarmament after World War II. The U.S. Far East Command collected 58 M4A3E8 scattered throughout Japan, created the 8072nd Temporary Tank Battalion (later renamed to the 89th Tank Battalion) on 17 July and landed them in Busan on 1 August. The 8072nd Temporary Tank Battalion was immediately deployed for [[Battle of Masan]] to support the 25th U.S. Infantry Division.<ref name="Korean War : Weapons of the United Nations"/>

Since then, a total of 679 M4A3E8 were deployed on the Korean Peninsula in 1950.<ref name="Korean War : Weapons of the United Nations"/> The M4A3E8 and [[T-34]]-85 were comparable and could destroy each other at normal combat ranges, although the use of [[High Velocity Armor Piercing|High-Velocity Armor Piercing]] ammunition, advanced optics, and better crew training gave the Sherman an advantage.{{sfn|Zaloga|2001}} The M4A3E8, using 76&nbsp;mm HVAP ammunition, destroyed 41 enemy tanks from July to November 1950.{{sfn|Zaloga|2010|p=74–77}}

The M4A3E8 had weaker anti-tank combat capability compared to the larger caliber [[M26 Pershing]] and the [[M46 Patton]] that were operated at the same time. However, the lighter M4A3E8 became the preferred U.S. tank in the later phases of the war. It was considered more advantageous in terms of maneuverability on rough terrain and ease of maintenance due to the mechanical reliability. Because of this feature, the M4A3E8 were widely used for providing close support to infantry units, particularly during battles for high ground and mountains.<ref name="Korean War : Weapons of the United Nations"/>

From December 1951, around 20 M4A3E8s saw service with the [[Republic of Korea Marine Corps]] during the war while the [[Republic of Korea Army|Army]] operated [[M36 tank destroyer|M36 GMCs]] as its main armored asset.<ref name="Korean War : Weapons of the United Nations">{{Cite book |last=Bak |first=Dongchan |url=http://medcmd.mil.kr/user/imhc/upload/pblictn/PBLICTNEBOOK_202105270240172800.pdf |title=Korean War : Weapons of the United Nations |publisher=Ministry of Defense Institute for Military History |date=March 2021 |isbn=979-11-5598-079-8 |location=Republic of Korea |language=Korean |access-date=2022-06-27 |archive-date=2022-09-20 |archive-url=https://web.archive.org/web/20220920170621/http://medcmd.mil.kr/user/imhc/upload/pblictn/PBLICTNEBOOK_202105270240172800.pdf |url-status=dead}}</ref>
