Tank History
A bit of research on Wikipedia reveals that the British Mark I tank entered service in August 1916, becoming the world’s first combat tank. It was developed during World War I to combat the trenches and machine guns that dominated the battlefields of the Western Front. Despite the primitive nature of the first “tank,” a designation chosen to maintain secrecy, it was able to deal successfully with the various tasks found on the battlefields: small-arms fire, fortified enemy positions, challenging terrain, and the need to carry supplies. The Mark I’s first combat usage was on September 15, 1916, during the Battle of Flers-Courcelette, part of the Somme Offensive.
