Recce 30AU is a British Recon unit.
30AU refers to the No. 30 Commando, known from 1943 as the 30 Assault Unit. Originally formed to gather intelligence, the unit was involved in 1942 in the Dieppe Raid and then the Operation Torch landings later that year. Although their first mission was an operational failure, the second assignment resulted in the procurement of detailed strategic intelligence of Italian and German fleet dispositions, together with code books and other vital intelligence. After a distinguished service in Greece, Norway, and Italy, the unit returned to the United Kingdom in preparation for the Normandy landings.
In 1944, 30 AU landed on Juno and Utah beaches, capturing the Douvres-la-Delivrande radar station, and continuing a successful combat record through Cherbourd, Rennes, rest, the Liberation of Paris, and spearheaded assaults on the Channel coast ports. Their ultimate assignment was in Germany, and the details of their operations remain classified. From what little is known about 30 AU operations, they were involved in the capture of key Nazi researchers, including Wernher von Braun and Walter Dornberger.
The Lanchester submachine gun was produced by Sterling Armaments Company. RAF need a submachine gun to defend their airfields after the Dunkirk evacuation. These were a copy of the German MP 28 since they did not have the time to create their own. The Royal Navy decided to adopt the weapon. These were used by the Royal Navy as landing party weapons. Unlike their Sten counterparts, Lanchester were well made.
