The Royal Tank Regiment or RTR is the oldest tank regiment in the world. The RTR was formed as early as 1916 during the Great War by the British Army. Originally formed from the Machine Gun Corps, the pioneers of armoured warfare became the Tank Corps, who formed 8 battalions by the start of 1919. During the Second World War, the RTR, had 25 battalions fighting all over the world. Currently the regiment is based at Tidworth and is equipped with Challenger 2 tanks. Their official uniform is unique to the rest of the Royal Armoured Corps; instead of the standard-issue blue beret, the RTR wear a black one. Their uniform of black coveralls is also reserved especially for the Regiment. Soldiers in the RTR also wear a cap badge which shows an image of an early Royal Tank Regiment tank. Their motto is ‘Fear Naught’. During the First World War, walking sticks were often used by officers to probe the ground in front of their tanks to test the firmness. Often, the commanders led their tanks into action on foot. More recently to commemorate this, officers of the Regiment carry ash plant sticks instead of the short cane customary to other arms.
