The First World War, which lasted from 1914 to 1918, marked the debut of tanks on the battlefield. These armored vehicles were developed to break the stalemate of trench warfare and provide a new form of mobile combat power. Tanks were designed to cross difficult terrain and withstand small arms fire, making them a revolutionary addition to military technology.


The Mark I was the first-ever tank, developed by the British in 1916. It came in two versions: "Male" tanks, which were equipped with guns, and "Female" tanks, which had machine guns. The Mark I had a distinctive rhomboid shape, which allowed it to cross trenches more effectively.


The Renault FT was a French tank introduced in 1917. It was one of the first tanks to feature a fully rotating turret, which became a standard feature in future tank designs. The FT was highly maneuverable and effective in combat, influencing tank design for years to come.


The Medium Mark A Whippet was another British tank from World War I. Unlike the Mark I, the Whippet was designed primarily for infantry support and to engage enemy machine gun positions. It was equipped with multiple machine guns and had a lighter, more agile design.
