No. 1 Demolition Squadron was formed specifically to attack Field Marshal Rommel's fuel supplies, in support of General Montgomery’s offensive at El Alamein, at the suggestion of Lieutenant-Colonel John Hackett. The unit became operational on 10 December 1942 as an 8th Army Special Forces unit. After the Long Range Desert Group (LRDG) and the Special Air Service (SAS), PPA was the last and smallest of the three main irregular raiding, reconnaissance and intelligence units formed during the North African Campaign.
