The Malaya Command was a formation of the British Army formed in the 1920s for the coordination of the defences of British Malaya, which comprised the Straits Settlements, the Federated Malay States and the Unfederated Malay States. It consisted mainly of small garrison forces in Kuala Lumpur, Penang, Taiping, Seremban and Singapore.

The American-British-Dutch-Australian (ABDA) Command, or ABDACOM, was the short-lived supreme command for all Allied forces in South East Asia in early 1942, during the Pacific War in World War II. The command consisted of the forces of Australia, the Netherlands, United Kingdom and the United States. The main objective of the command, led by General Sir Archibald Wavell, was to maintain control of the "Malay Barrier", a notional line running down the Malay Peninsula, through Singapore and the southernmost islands of the Dutch East Indies. ABDACOM was also known in British military circles as the "South West Pacific Command", although it should not be confused with the later South West Pacific Area command.
