Tank

Tanks were first invented during WWI by the British. The tank was to be able to cross trenches, crush barbed wire, and not be harmed by machine-guns. Armored cars had already been made and this prompted Major Ernest Swinton to make a tracked fighting vehicle. A committee was formed to oversee the project. The first tank created by this committee was a tank that was nicknamed Little Willie. This tank was tested by the British military in 1915 and was first called a landship. This was later shortened to the word tank. The French also developed a tank that was based off a Holt caterpillar. This tank was first used in 1917. Tanks eventually made trench warfare obsolete and would later become one of the best fighting machines on the planet.
