On 5 July 2012, it was announced that these two regiments would be amalgamated to form a single regiment, to be called simply The Royal Tank Regiment. The official regimental motto is Fear Naught; while the unofficial motto (signified also by the colours of the tactical recognition flash) is "From Mud, Through Blood to the Green Fields Beyond."
