The Royal Naval air service launched the first armored car squadron. Several of them were sent to Britain's colonies, two even went to Gallipoli. In 1920 the armored cars were modernized and several were used to fight the IRA.
In World War II seventy-six of the Rolls-Royce armored cars were in service and took part in the battles in the Western desert and Syria. By the end of 1941 the armored cars were retired but saw some use with the British Home Guard.
