The Tank Corps was a military unit formed during World War I, specifically designed to operate tanks on the battlefield. Established in 1917 by the British Army, it aimed to enhance mobility and break through enemy lines. The introduction of tanks marked a significant shift in warfare, as they provided protection for soldiers and could traverse difficult terrain. The Tank Corps played a crucial role in several key battles, including the Battle of Cambrai in 1917, where tanks were first used en masse. Over time, the success of the Tank Corps led to the development of armored warfare tactics, influencing military strategies in future conflicts.
