Cap Badge - Army Ordnance Corps In July 1896, Queen Victoria approved the War Office recommendation that, of the arms of the Board of Ordnance, the shield of arms, but not the crest nor supporters of the motto, be incorporated into the badge of the Army Ordnance Department (AOD) and Corps (AOC). It was considered that the Army Ordnance Department and Corps should be granted the privilege of the use of the arms of their ancestors as the main motif of their emblem. Two cap badges were created, one for the Army Ordnance Department (Officers) and the other for the Army Ordnance Corps (Junior Officers & Soldiers) were of similar design, differing only in the wording on the scroll, The AOC badge has ARMY ORDNANCE CORPS on the scroll, while the AOD badge just has the one word ORDNANCE.
