The 'Pentropic' Organisation
1960:
The Australian Army adopted the Pentropic Organisation in 1960 and within its design, there was to be one SAS Company per Pentropic Division, with the primary role of long range and medium reconnaissance and battlefield surveillance. The SAS was neither organised, nor equipped to hold ground for protracted periods, nor to undertake standard infantry offensive operations. To adjust to the new SAS Company role, minor adjustments were made to its internal organisation. In outlining the capabilities of the SAS Company, Army Headquarters stated that when the situation demands, the SAS can operate on a jeep mounted basis, but will usually operate on foot in jungle terrain, even if the initial move to the start point of a patrol is made by sea or air. The subsequent operations, if on foot, will be slow, the duration of patrols where local inhabitants are unfriendly, will depend on the amount that can be man-packed and the practicability of resupply.
The missions that might possibly be allotted to the SAS at that time were:
• Medium reconnaissance in advance of the forward troops;
• Maintain watch on / and flank protection;
• Long range reconnaissance behind enemy lines;
• Small-scale harassing operations behind enemy lines;
• Internal security tasks; and Traffic control when not required for other tasks
