One squadron of the British Army's 22 Special Air Service regiment was deployed to Borneo in early 1963 in the aftermath of the Brunei Revolt to gather information in the border area about Indonesian infiltration. There was a British Army presence until the end of the campaign. Faced with a border of 971 miles, they could not be everywhere, and, at this time, 22 SAS had only three squadrons. Also present were the Special Boat Service (SBS) of the Royal Marine Commandos. They had two sections based in Singapore. Tactical HQ of 22 SAS deployed to Kuching in 1964 to take control of all SAS and SBS operations. The shortage of SAS and SBS personnel was exacerbated by the need for them in South Arabia, in many ways, a far more demanding task in challenging conditions against a cunning and aggressive opponent.
