You do know that the "greese gun" was a gun used by U.S. paratroopers in WW11
The M3 Machine pistol? Yes I know about it, that was a sort of joke on my part.
The M3 was called the Grease Gun because it looks like an auto mechanic's grease gun. It was supposed to replace the Thompson after American planners noticed how effective the MP40 and Sten machine guns were, the idea was a cheap to mass produce disposable sub machine gun in the vein of the Sten. Every ww2 paratrooper from the UK had a Sten as well as any other weapon they may be carrying, the appeal of every soldier having an smg was obvious.
In the end it proved neither as cheap/lightweight/compact/disposable as the Sten or as effective as the Thompson, so it never really replaced either and the M-14 put pay to it being standard issue. Having said that US Tank crews were still carrying them as recently as the first Gulf War.
