The term “Commando Mark 45 Tommy Gun” appears to be a misnomer, blending elements from different firearms. The Thompson submachine gun, commonly known as the “Tommy Gun,” saw extensive use during World War II and later conflicts. Various models existed, but none were specifically designated “Mark 45.” The term “Commando” might refer to specialized units or modifications, potentially shortening the barrel for close-quarters combat as seen in some Thompson variants. A detailed examination of historical records and firearms literature is necessary to clarify the origin and validity of this combined terminology.
The Thompson submachine gun played a significant role in 20th-century warfare. Its .45 ACP cartridge delivered substantial stopping power, and its select-fire capability offered both semi-automatic and fully automatic firing modes. This weapon became associated with military and law enforcement units, impacting close-quarters combat tactics and popular culture. Understanding the historical context of this weapon illuminates its influence on small arms development and its place in military history.
