World Wars I and II Tank Poster
Tanks in World War I were developed separately and simultaneously by Great Britain and France as a means to break the deadlock of trench warfare on the Western Front. Their first use in combat was by the British Army in September 1916 during the Battle of the Somme. Germany was unconvinced of the tank's potential, and built only twenty.
Tanks of the interwar period evolved into the much larger and more powerful designs of World War II. During World War II, Germany began their large-scale armored campaigns to break through the enemy front and collapse enemy resistance.
