Immortalized countless times in movies about the war of Vietnam or in the hands of Sylvester Stallone characterized as Rambo, the M60 machine gun was adopted by United States Army in 1957.
Developed by Maremont Corporation heavily inspired by World War II German designs such as the FG-42 machine gun and MG-42 machine gun, the final configuration called the T161E3 was chosen to replace the M1918 Browning machine gun and the M1919A6 machine gun of the same company.

The M60 is a gas-operated general-purpose machine gun, fed by 100-round belts held together by disintegrating links, chambered in the 7.62x51mm, which fires with the breech open and is usually operated by two people they distribute ammunition and spare cannons.
It entered service in 1959 and was rapidly deployed among units deployed in Vietnamwhere he quickly gained the support of “the Pig” (the sow) due to its weight of more than 10 kilos and the speed with which it swallowed the ammunition (rate of 550 shots per minute).
Among its features was the barrel change system (an aspect always forgotten in the cinema) since sequences of 200 rapid shots overheated it and made it necessary to replace it using asbestos gloves to avoid burns since it did not have a handle. It had a folding bipod welded directly to the barrel, although it was also mounted on tripods and mounts for vehicles, helicopters and boats, a use with which it has remained until today.

In the 1980s it began to be replaced by the M249 (Squad Automatic Weapon or SAW, a machine gun chambered in the lighter 5.56x45mm caliber. designed by the Belgian FNH. However its greater firepower and range (up to 1,100 meters) kept the M60 mounted on vehicles in service.
The Marine infantry it was given another chance and the aforementioned lighter M60E3 variant was adopted, with a front pistol grip to improve grip and with the bipod attached to the receiver instead of the barrel, among other improvements.
The navy seals they continued to trust it, and in the 1990s the manufacturer Saco Defense developed another variant from the E3 with greater reliability, shorter barrel and redesign of the operating system and adopted as Mk43 Mod 0 and marketed as M60E4.

However, its luck as a squad weapon was cast and in 1994 the US Army launched a replacement program in which it competed with the M240 (US name of the GPMG, also of the Belgian FNH), which finally ended it. substituting, above all for its greater reliability, remaining in service in reserve units and on vehicles as well as in the Navy Seals.
