The Crude $15 Weapon That Outlived the Thompson for Decades
US paratroopers in Normandy were handed a $15 piece of plumbing—the M3 Grease Gun. They hated it on sight. But this crude, rattling metal tube was a tactical cheat code that outlasted the legendary Thompson for decades. In this tactical military history breakdown, TeamAlphaSix exposes the untold reality of the M3 Grease Gun (the "Greaser"). Discover why its slow rate of fire made it a CQB monster, how car factory engineering from General Motors made it virtually indestructible, and the cold arithmetic that kept this WW2 submachine gun in US tank crews' inventory until the Gulf War in 1991. We deconstruct the ballistic superiority of the .45 ACP in a stamped-steel frame and why the "ugly" weapon was actually the Pentagon's most efficient engineering success.
