m60 (machine gun)
An American belt-fed 7.62×51mm NATO machine gun, first adopted by the United States army in 1957. The M60 was widely used by the US military during the Vietnam War. Due to several design flaws, it was largely supplanted by the M240 which is a derivative of the Belgian FN MAG and the light machine gun M249 saw SAW.
The M60 gained the nickname "The Pig" due to its bulky size and appetite for ammunition. The weapon is popularly depicted in many video games and war films like Commando, Full Metal Jacket and Rambo.
