MG 42
Probably hard to narrow it down to only one.
The Maxim was amazing when it was first invented.
Te MG-42 may have been the best ever.
The M2 was invented in 1917 but due to the end of WWII was not adopted until several years later. It is still in use 100 years later so maybe it deserves the title.
The Ferrari of machine guns.
Yeah, that’s what I was thinking. Innovative. Deadly. And served as our prototype for the M60.
The MG42/8mm Mauser won’t first immobilize and then disassemble a thin-skinned vehicle. The Ma Deuce/.50 BMG will.
And in the right hands, a Ma Deuce will put one though the lower brain housing group of a VC from 2500 yards.
