The 2nd Armoured Division was formed at Fort Benning, Georgia on 15 July 1940, originally commanded by Major General Charles L. Scott, with Colonel George S. Patton in charge of training. Scott was promoted to command the I Armoured Corps in November of that year, which put Patton, now a brigadier general, in command of the division. The Division served with the First, Seventh, and Ninth Armies The 2nd Armoured was organised as a "heavy" armoured division having two armoured regiments of four medium tank and two light tank battalions of three companies each. Along with the 3rd Armoured Division, it retained its organisation throughout World War II while all 14 other U.S. armoured divisions were reorganised as "light" armoured divisions having three tank battalions, each consisting of three medium tank companies and one light tank company. Both types had an infantry component of three mechanised battalions, although the heavy divisions maintained an "armoured infantry regiment" organisation.
