Thompson submachine guns were used by both sides during the [[1948 Arab-Israeli war]].{{sfn|Yenne|2009|p=263}} Following the war, Thompsons were issued to members of Israel's elite [[Unit 101]], upon the formation of that unit in 1953.<ref name="Eilam">{{cite book|last= Uzi|first= Eilam|title= Eilam's Arc: How Israel Became a Military Technology Powerhouse|publisher= Sussex Academic Press|year= 2011|page=7}}</ref>

During the [[Greek Civil War]], the Thompson submachine gun was used by both sides. The [[Hellenic Armed Forces]], gendarmerie and police units were equipped with Thompson submachine guns supplied by the British and later in the war by the United States. The opposing Communist fighters of the [[Democratic Army of Greece]] were also using Thompson submachine guns, either captured from government forces or inherited from [[Greek People's Liberation Army|ELAS]]. ELAS was the strongest of the resistance forces during the period of [[Greek Resistance]] against the Germans and Italians and were supplied with arms from both the British and the United States. After the demobilization of ELAS, an unspecified number of arms were not surrendered to the government but kept hidden and were later used by the Democratic Army of Greece.<ref name="Sazanidis">{{harvnb|Sazanidis|1995|pp=293–295}}</ref>

The Thompson also found service with the [[Royal Netherlands East Indies Army|KNIL]] and the [[Netherlands Marine Corps]] during their [[Indonesian National Revolution|attempt]] to retake their former colony of Indonesia.<ref name="ArmsControl">{{cite book|title=The Control of local conflict : a design study on arms control and limited war in the developing areas|volume=3|last1=Bloomfield|first1= Lincoln P.|last2=Leiss|first2=Amelia Catherine|last3=Legere|first3= Laurence J.|last4= Barringer|first4= Richard E.|last5=Fisher|first5= R.

By the time of the [[Korean War]] in 1950, the Thompson had seen much use by the U.S. and South Korean military, even though the Thompson had been replaced as standard-issue by the M3/M3A1. With huge numbers of guns available in army ordnance arsenals, the Thompson remained classed as Limited Standard or Substitute Standard long after the standardization of the M3/M3A1. Many Thompsons were distributed to the US-backed Nationalist Chinese armed forces as military aid before the fall of [[Chiang Kai-shek]]'s government to [[Mao Zedong]]'s communist forces at the end of the [[Chinese Civil War]] in 1949 (Thompsons had already been widely used throughout China since the 1920s, at a time when several Chinese warlords and their military factions running various parts of the fragmented country made purchases of the weapon and then subsequently produced many local copies). During the Korean War, US troops were surprised to encounter [[People's Volunteer Army|communist Chinese troops]] armed with Thompsons (amongst other captured US-made Nationalist Chinese and American firearms), especially during unexpected night-time assaults which became a prominent Chinese combat tactic in the conflict. The gun's ability to deliver large quantities of short-range automatic assault fire proved very useful in both defense and assault during the early part of the war when it was constantly mobile and shifting back and forth. Many Chinese Thompsons were captured and placed into service with American soldiers and marines for the remaining period of the war.

The [[Yugoslav People's Army|Yugoslav Army]] received 34,000 M1A1 Thompsons during the 1950s as part of a US Military Aid to Yugoslavia Agreement. These guns were used during the [[Yugoslav Wars]] in the 1990s.<ref name="Yugoslav Army">{{cite book|title=Yugoslavia and After: A Study in Fragmentation, Despair and Rebirth|first1=David A. |last1=Dyker |first2= Ivan |last2= Vejvoda|edition=1st|date= 9 December 1996|location= London|publisher= Routledge|isbn= 9781317891352 |page=120|url=https://books.google.com/books?id=7VmPBAAAQBAJ&pg=PT169}}</ref>

During the [[Cuban Revolution]], the Thompson submachine gun was used by both [[Fulgencio Batista|Batista]]'s army and [[Fidel Castro]]'s guerrillas. Both the latter and the [[Brigade 2506]] also used some during the [[Bay of Pigs Invasion]].<ref name="Cuba">{{cite book|title=The Bay of Pigs: Cuba 1961|series = Elite 166|first=Alejandro |last=de Quesada |date=10 January 2009|isbn=9781846033230|url=https://books.google.com/books?id=EE-1CwAAQBAJ|pages= 9, 60–61}}</ref>

During the [[Vietnam War]], some [[Army of the Republic of Vietnam|South Vietnamese army]] units and defense [[militia]] were armed with Thompson submachine guns, and a few of these weapons were used by reconnaissance units, advisors, and other American troops. It was partially replaced by the [[MAC-10]], albeit during Vietnam, the fully automatic fire provided by the [[M16 rifle|M16]] made the Thompson less effective than it previously had been. Still, not only did some U.S. soldiers have use of them in Vietnam, they encountered them as well. The [[Viet Cong]] liked the weapon and used both captured models as well as manufacturing their own copies in small jungle workshops.<ref>{{cite web|url=http://www.williammaloney.com/Aviation/WestPointMilitaryMuseum/SubmachineGuns/pages/12VietCongHomemadeThompsonSubmachineGun.htm|title=12 Viet Cong Homemade Thompson Submachine Gun|website=www.williammaloney.com|access-date=2018-05-13|archive-date=2019-01-18|archive-url=https://web.archive.org/web/20190118074643/http://www.williammaloney.com/Aviation/WestPointMilitaryMuseum/SubmachineGuns/pages/12VietCongHomemadeThompsonSubmachineGun.htm|url-status=dead}}</ref>

The Australian government destroyed most of their Thompson machine carbines in the 1960s. They shipped their remaining stocks to arm the forces of [[Lon Nol]]'s [[Khmer Republic]] in 1975. They were then captured and used by the [[Khmer Rouge]].{{cn|date=December 2023}}

During [[the Troubles]] (1969–1998), the Thompson was again used by the Irish Republican paramilitaries. According to historian [[Peter Hart (historian)|Peter Hart]], "The Thompson remained a key part of both the [[Official IRA]] and [[Provisional IRA]] arsenals until well into the 1970s when it was superseded by the [[Armalite AR-18|Armalite]] and the [[AK-47]]."{{sfn|Hart|2003|p=191}}

The Thompson was also used by U.S. and overseas law enforcement and police forces, most prominently by the [[Federal Bureau of Investigation|FBI]]. The FBI used Thompsons until they were declared obsolete and ordered destroyed in the early 1970s.<ref>{{cite magazine|last=Vanderpool|first=Bill|title=Bring Enough Gun|magazine=[[American Rifleman]]|publisher=National Rifle Association|date= October 2013 |pages=80–85&115–116}}</ref>
