SAS Secret War reveals how small teams of SAS men were sent to fight in Oman where Communist guerillas were waging a savage campain.

Fighting the enemy on their own terms, the SAS changed the course of the war. A small force of elite soldiers showed how Communist guerrillas could be defeated on their own ground.
