US Army Training Film TF9-2218

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 M54 5-ton 6×6 truck (G744) was the basic cargo model of the M39 Series truck. It was designed to transport a 10,000 lb (4,500 kg), 14-foot-long (4.3 m) cargo load off-road in all weather. In on-road service the load weight was doubled.

The M54 was the primary heavy cargo truck of the U.S. Army and U.S. Marine forces during the Vietnam War, and was also used by the U.S. Navy, U.S. Air Force, and ARVN forces.

The M39 Series began to be replaced by the M809 series in 1970, followed by the M939 series in 1982, but continues to serve in other nations' armed forces around the world...

This may involve recovering a vehicle damaged in an accident, returning one to a drivable surface in a mishap or inclement weather, or towing or transporting one via flatbed to a repair shop or other location.

A tow truck is distinct from a motor carrier that moves multiple new or used vehicles simultaneously in routine transport operations...

The tow truck was invented in 1916 by Ernest Holmes, Sr., of Chattanooga, Tennessee, a garage worker inspired after needing blocks, ropes, and six men to pull a car out of a creek. Upon improving his design he began manufacturing them commercially. The International Towing and Recovery Hall of Fame and Museum in his home town displays restored antique wreckers, tools, equipment, and pictorial histories of the industry Holmes created...
