Tanks in World War II

Combined arms in action: a WWII tank (M4 Sherman shown) was effective against a wide range of targets, but often needed support of infantry to protect it against close attacks
The Tiger I heavy tank could use its long ranged powerful gun to advantage in the open landscapes of the Battle of Kursk, 1943

Tanks were an important weapons system in World War II. Although tanks in the inter-war years were the subject of widespread research, few were made, in just a few countries. However, during World War II, most armies employed tanks, and thousands were built every month. Tank usage, doctrine, and production varied widely among the combatant nations. By war's end, a consensus was forming on tank doctrine and design.
