No. 114 MCRU deployed to Malaya in 1958, becoming operational at RAAF Base Butterworth on 19 August. It took over responsibility for aerial surveillance and ground-controlled interception from the Royal Air Force's No. 487 Signals Unit on 1 December. From Butterworth, No. 114 MCRU directed the Sabre fighters of Nos. 3 and 77 Squadrons and the Canberra bombers of No. 2 Squadron in the last years of the Malayan Emergency. It also sent controllers on attachment to Ubon Air Base in Thailand, where No. 79 Squadron was based from 1962. On 3 September 1964, the unit went on to a 24-hour operational footing to support the Sidewinder-armed Sabres of Nos. 3 and 77 Squadrons during the "Konfrontasi" between Indonesia and Malaysia, though no combat ensued. "Konfrontasi" having been declared over in August 1966, No. 114 MCRU transferred its responsibilities to RAF Western Hill on 22 September, and disbanded at Butterworth on 31 October.
