How were tanks used ww1?

During World War I, tanks were introduced as a solution to break the stalemate of trench warfare. They were used to cross trenches and barbed wire, providing mobile firepower and support for infantry assaults.

Their effectiveness marked a significant evolution in military strategy and technology.
