The M4 Sherman medium tank was the first American tank to carry a 75mm main gun mounted on a fully traversing turret. Powered by a 500 horsepower, liquid-cooled, V -type Ford engine, the tank could achieve 26 miles per hour on a paved road, and had a highway range of over 150 miles on a single, 174-gallon tank of fuel. Over 50,000 Shermans of various types were built during WWII. Intended as a manual for those charged with operation and maintenance of the M4A3 Sherman, this manual shows the basics of how to drive the tank and take care of its 8-cylinder, liquid-cooled engine. The book also contains chapters on lubrication and inspections. Originally printed in 1942 and labeled restricted, this manual was declassified long ago and is here reprinted in book form. Care has been taken to preserve the integrity of the text.
