 Browning expressed his opinion that the force must not be sacrificed in " penny packets " , and urged the formation of a third brigade . Permission was finally granted in July 1942 , and the 2nd Parachute Brigade , commanded by Brigadier Ernest Down , was formed . The 2nd Parachute Brigade was assigned the existing 4th Parachute Battalion , and two new battalions converted from line infantry units , the 5th ( Scottish ) Parachute Battalion , converted from the 7th Queen 's Own Cameron Highlanders , and the 6th ( Royal Welch ) Parachute Battalion , from the 10th Royal Welch Fusiliers .
