The first tanks were produced from late 1914 by Great Britain and France to break the deadlock of trench warfare on the Western Front. Their first use was during the Battle of the Somme in 1916. Britain and France built thousands of tanks, while Germany only developed and bought into service 20 vehicles of a single design. In this video, we look at the development of tanks throughout history including the German tank divison, Russian tanks and U.S. tank development. We also look at tanks in the Cold War. While they would not only continue to be produced in huge numbers the technology advanced dramatically making them larger with thicker armour and generally much more effective.
