The Royal Tank Regiment, the oldest tank unit in the world, will commemorate 100 years since the Battle of Cambrai

The Royal Tank Regiment commemorates the anniversary of the battle annually on Cambrai Day (20^th November). It is the most important day in the Regimental calendar, and is commemorated wherever its troops find themselves, from the battlefields of the Second World War, to the deserts of Afghanistan, to their current barracks in Tidworth, Wiltshire.
