To advance over obstacles like barbed wire, to conceal troops behind it, to scare the enemy, to attack machine gun positions.
The Tank.
The British. They were trying to disguise what they were, and said they were a new kind of water tank.
The first military tank was invented by Englishman Sir Albert Gerald Stern, who was a key figure in the development of the tank during World War I. Working with a team at the British Army's Landship Committee, Stern played a crucial role in the design and production of the Mark I tank, which made its debut in 1916. The tank was developed to overcome the challenges of trench warfare and to provide mobile firepower on the battlefield.
No single individual person invented the military tank. Mr. (later Sir) Eustace Tennyson d'Eyncourt head of the British "Landships Committee" during WWI is the closest person that can be credited for inventing the military tank. It was under his supervision that the FIRST army tanks were designed, built, and fielded onto the battlefields during WWI.
the US Army invented the Sherman tank.
