Major General Walter Walker took over as COMBRITBOR and Director of Operations (DOBOPS) on 19 December with command of all land, sea and air forces assigned to Borneo and reporting directly to the Commander-in-Chief Far East Forces, Admiral Sir David Luce. Three weeks after the rebellion started, 99th Gurkha Infantry Brigade had 5 infantry battalions and HQ 3rd Command Brigade was in Kuching. This force was supported by the Brunei Malay Regiment, the Sarawak Rangers, police of the three territories including paramilitary Police Field Force, and Harrison’s force of now 4,000 Dayaks. Suitable coastal patrol naval vessels were lacking (the Royal Navy didn’t have any) so minesweepers were used. The RAF had medium and short range transport aircraft. In January, the Queen's Own Highlanders and 1/2 Gurkhas were replaced by the King's Own Yorkshire Light Infantry and 1/7 Gurkhas and special forces troops had also arrived.
