In the final period of WWI the Rolls Royce Armored Car was widely used only in the deserts of the Middle East and North Africa, since there was almost no work in Europe for them. But in 1916 these cars were used with great effectiveness in Ireland to suppress mass unrests. So, in the shape of the Rolls Royce and quite differently from its original purpose, for the first time in history the armored car became a specialized police unit. Later, the Irish government purchased 13 of these cars, which were used with considerable success by the Army and the country's police.
After WWI, the Rolls Royce Armored Cars did not suffer the fate of many other new types of armament, which in most cases were sent for scrap. After a series of upgrades, this armored car though significantly changed from its original appearance, remained in combat units right up until 1944 when the next great war, WWII, was coming to its end.
