Question: When did the first commanding officer of the 6th Airlanding Brigade join the military? Passage:On 23 April 1943, the War Office gave permission to raise a second airborne division, the 6th Airborne. The division comprised the 3rd and 5th Parachute Brigades and the 6th Airlanding Brigade, giving it two parachute and one airlanding brigades, which became the standard British complement for an airborne division. In May 1943 Brigadier Hugh Kindersley was appointed as the airlanding brigade's first Commanding Officer (CO). Under his command he had two experienced battalions transferred from the 1st Airlanding Brigade: the 2nd Battalion, Oxfordshire and Buckinghamshire Light Infantry (2nd OBLI) and the 1st Battalion, Royal Ulster Rifles (1st RUR). They were joined by a unit newly transferred to the airborne forces, the 12th Battalion, Devonshire Regiment (12th Devons), a hostilities-only unit formed during the war, as the brigade's third infantry battalion. Other units assigned around the same time were the 53rd (Worcestershire Yeomanry) Airlanding Light Regiment, Royal Artillery, the 249th (Airborne) Field Company, Royal Engineers and the 195th (Airlanding) Field Ambulance, Royal Army Medical Corps.
