What damage did the World War 1 tanks do?

World War I tanks caused significant damage on the battlefield by breaking through entrenched positions and barbed wire defenses, which had been difficult for infantry to penetrate. Their armored protection allowed them to withstand small arms fire and artillery, enabling them to support troop advances. Tanks also inflicted psychological terror on enemy soldiers and contributed to the shift in warfare tactics from static trench warfare to more mobile forms of combat. However, their mechanical reliability and limited operational range often hampered their effectiveness.
