Page 9 of "An Introduction to Iraq" provides a brief history of the Armoured Car Companies, from 1915 when Amoured Car Companies 1 and 2 were part of the Tank Corps employed in fighting against the Turks in Mesopotamia in the Battle of Ctesiphon to 1935 when four new Armoured Car Companies, part of the Royal Air Force, were supporting the RAF in defending its landing grounds and bases as well as long distance reconnaissance. At the time of this publication (August 1935) the commanding officer of the No 1 Armoured Car Company RAF (re-formed in April 1930 as an amalgamation of RAF Armoured Car Companies 3, 4, 5 and 6) was Squadron Leader  (later Group Captain) Ronald S Sugden, CBE, AFC. For more details on the formation of Nos 3, 4, 5 and 6 RAF Armoured Car Companies, please click HERE and if you would like a comprehensive account of the 'RAF ARMOURED CAR COMPANIES IN IRAQ 1921 - 1947' written by Dr Christopher Morris, I recommend that you read his article in the Royal Air Force Historical Society Journal No 48.​​
