11 SAS Battalion was formed from No 2 Commando on 21 November 1940, retaining the No 2 Commando CO Lt Col CIA Jackson. In 1941 he was succeeded by Lt Col EE Down.
The battalion retained its Commando structure, of 22 eight-men teams trained to infantry section standard. This was increased to 10 because the numbers conformed to a Whitley aircraft ‘stick’ of parachutists.

On 15 September 1941 the unit name changed to the 1st Parachute Battalion.
