Tank Drawing

Usually, tanks carry smaller calibre armament for short-range defence where fire from the main weapon would be ineffective, for example when engaging infantry, light vehicles or aircraft. A typical complement of secondary weapons is a general-purpose machine gun mounted coaxially with the main gun, and a heavier anti-aircraft machine gun on the turret roof. These weapons are often modified variants of those used by infantry, and so utilise the same kinds of ammunition.
At the Battle of Kursk a Tiger I commanded by Michael Wittmann survived a ramming by a T-34. Whittmann's driver was able to back away from the T-34 which was destroyed when its ammunition exploded.
