During the Battle of Britain in an attack on RAF Kenley by Dornier 17 bombers, AC2 David Roberts, RAF Regiment, downed one of the two attacking aircraft destroyed using the RAF's newest anti-aircraft weapon, a line of twenty-five rockets that deployed a barrage of 500 foot cables suspended by parachutes. This weapon - the naval version of the Z Barrage - was symptomatic of the hodge-podge of weapons issued to the RAF Regiment in the early war years, The other Dornier 17 was shot down by Corporal John Miller of the Scots Guards, using a Lewis gun. For this action both men received the Military Medal.
