A friend of mine is looking to discover the formation sign for the 30 Assault Unit. This unit was the brainchild of Ian Fleming and was a small, highly mobile fighting unit charged with securing information, material and prisoners of high military intelligence value. As a Royal Navy unit, underwater warfare targets were a priority for 30AU but, after D-Day, V1 and V2 sites became targets.
In NW Europe, 30AU had wheeled armoured vehicles and various soft skins. The softskins generally had RN census numbers such as 54201 RN for a Dodge Weapons Carrier but its Jeeps had census numbers with the standard M prefix. Staghound armoured cars had the standard F prefix but C15TA armoured carriers had RN census numbers. The Arm of Service was a white 30 (disregarded WO regulations) on a blue background.
But what did it use as its formation sign? A blue fouled anchor on a white circle has been suggested.
Can anyone help on this?
