'FEATURES AND CAPABILITIES - TECHNIQUES FOR CLEARING, LOADING, FIRING AND UNLOADING WEAPONS - METHODS AND PROCEDURES FOR DISASSEMBLY AND ASSEMBLY OF THE SIX MAIN COMPONENT GROUPS OF WEAPONS.
Originally a public domain film, slightly cropped to remove uneven edges, with the aspect ratio corrected, and one-pass brightness-contrast-color correction & mild video noise reduction applied.
The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original).

The M73 and M219 are 7.62 mm NATO caliber machine guns designed for tank use. NATO no longer uses them, but they were used on the M48 Patton and M60 Patton MBT series (including the M728 Combat Engineer Vehicle), and on the M551 Sheridan Armored Reconnaissance / Airborne Assault Vehicle (AR/AAV)...
Design and development
Designed primarily as a coaxial machine gun by the Rock Island Arsenal and produced by General Electric, the M73 was developed as a replacement for the M1919A4E1, M1919A5, and M37 machine guns that continued to serve in the immediate post–World War II environment.
The Machine Gun, 7.62-MM, M73 was officially adopted in 1959. It is an air-cooled, recoil-operated machine gun, but also using cartridge gasses to boost recoil. Though designed as a simplified alternative to the M1919 series, it is of almost identical weight. The weapon is fitted with a quick-change barrel, pull-chain charging assembly, and can be made to feed from the left or the right hand side (though the left-hand feed is more common).
An attempt to make the M73 useful as a flexible infantry gun saw the weapon fitted with sights and a pistol grip trigger as the Machine Gun, 7.62-MM, M73C. Equally unpopular, very few of these weapons were produced. Sources claim that it saw limited use in Vietnam.
The M73 suffered from numerous malfunctions and was prone to jamming. An improved M73E1 was eventually developed in 1970 with a simplified ejection system, being type classified as the Machine Gun, 7.62-MM, M73A1. In 1972, it was decided that this weapon was sufficiently different from its predecessor and was redesignated Machine Gun, 7.62-MM, M219. These weapons were eventually replaced by the M60E2 and M240 machine gun, and vehicles still in service using the M73 series were refitted with these weapons...
