The Malayan campaign, referred to by Japanese sources as the Malay Operation , was a military campaign fought by Allied and Axis forces in Malaya, from 8 December 1941 – 15 February 1942 during the Second World War. It was dominated by land battles between British Commonwealth army units and the Imperial Japanese Army, with minor skirmishes at the beginning of the campaign between British Commonwealth and Royal Thai Police. The Japanese had air and naval supremacy from the opening days of the campaign. For the British, Indian, Australian, and Malayan forces defending the colony, the campaign was a total disaster.

The Marmon-Herrington Armoured Car was a series of armoured vehicles that were produced in South Africa and adopted by the British Army during the Second World War. RAF Armoured Car companies possessed them, but seem never to have used them in action, making greater use of Rolls-Royce Armoured Cars and other types.
