By 17 December 42 Commando was complete in Brunei and 1st Green Jackets (43rd and 52nd) had landed from the cruiser HMS "Tiger" in Miri. 40 Commando aboard the commando carrier HMS "Albion" was diverted from Miri to Kuching. On 14 December, most of the unit reinforced the artillery battery sent there as infantry on 12 December to pre-empt trouble from the Chinese of the Clandestine Communist Organisation (CCO) who were openly sympathetic to the Brunei rebels. The last company of 40 Commando landed near Seria. "Albion" also provided helicopters from the embarked Naval Air Commando squadrons.
