"Although many Burmese fought initially for the Japanese as part of the Burma Independence Army, many Burmese, mostly from the ethnic minorities, served in the British Burma Army. The Burma National Army and the Arakan National Army fought with the Japanese from 1942 to 1944 but switched allegiance to the Allied side in 1945. Under Japanese occupation, 170,000 to 250,000 civilians died."
