FM 23-95 75-mm Tank Gun M2 (Mounted in Lee Medium Tank M3) Field Manual

The US 75-mm tank gun M2 was the standard American tank gun of the Second World War. The M2 originated from the famous French Canon de 75 modele 1897 field gun of World War I fame, which was also adopted by the United States and used well into World War II as the 75-mm M1897 field gun. The primary round fired by the M2 was the M48 High Explosive. This round traveled at 625m/s and contained 1.5 pounds of TNT filling. The M48 was available in two versions, standard or supercharge. Supercharge increased the propellent charge for greater muzzle velocity. Other important rounds fired by the 75-mm tank guns were the T30 Canister shot for use against troops in the open at short range, and two different types of armor-piercing rounds. The M2 was primarily mounted in the Lee Medium Tank M3. In Britain the tank was called by two names based on the turret configuration. Tanks employing US pattern turrets were called the "General Lee," named after Confederate General Robert E. Lee. Variants using British pattern turrets were known as "General Grant," named after U.S. General Ulysses S. Grant. Design commenced in July of 1940, and the first M3s were operational in late 1941. Created in 1942, this field manual reveals a great deal about the M2's design and capabilities. Intended as a manual for training purposes, it details the M2's assembly, maintenance, ammunition and accessories. Originally 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.
