I didn't know about "The Malayan Emergency", the long war against Communist terrorists in present day Malaysia that started after the Second World War. Back then still a British protectorate, this war involved troops from Britain and different countries of the Commonwealth, like New Zealand, Fiji and Southern Rhodesia.
Luckily for Malaysia, the Communist were mostly defeated by 1960, although insurgence revived in 1967 and opposed the Malaysian Government until peace was signed in 1989.
By the way, here is a useful graphic from Wikipedia to understand the formation of what is today Malaysia (something I still don't really do).
