In December 1963, the SAS went onto the offensive, now under the command of Lieutenant-Colonel John Woodhouse, adopting a "shoot and scoot" policy to keep SAS casualties to a minimum. They were augmented by the adding to their strength of the Guards Independent Parachute Company and later the Gurkha Independent Parachute Company. In 1964 Operation Claret was initiated, with soldiers selected from the infantry regiments in-theatre, placed under SAS command and known as "Killer Groups". These groups would cross the border and penetrate up to disrupting the Indonesian Army build-up, forcing the Indonesians to move away from the border. Reconnaissance patrols were used to enter enemy territory to identify supply routes, enemy locations and enemy boat traffic. Captain Robin Letts was awarded the Military Cross for his role in leading a reconnaissance patrol which successfully ambushed the enemy near Babang Baba in April 1965. The Borneo campaign cost the British 59 killed 123 wounded compared to the Indonesian 600 dead. In 1964 B Squadron was re-formed from a combination of former members still with the Regiment and new recruits.
