1. Malaya and Singapore (1941-1942): British forces, along with troops from the Commonwealth and other Allied nations, fought against the Imperial Japanese Army during the Malayan Campaign.

2. Burma (1942-1945): British and Indian forces engaged in fierce combat against Japanese forces in Burma, which was a crucial battleground in Southeast Asia. The British Army, supported by Allied troops, fought several major battles and campaigns against the Japanese in Burma, including the Battles of Imphal and Kohima in 1944.
3. Hong Kong (1941): British forces in Hong Kong resisted the Japanese invasion of the colony in December 1941. However, due to overwhelming Japanese strength, the British forces were defeated, and Hong Kong was occupied by Japan until the end of the war.
4. Pacific Islands Campaigns: British forces participated in various campaigns across the Pacific islands during World War II, including the Solomon Islands, New Guinea, and the Philippines. These campaigns often involved joint operations with American and other Allied forces.
Throughout the war, British forces were involved in land, sea, and air battles against Japanese forces. They also provided significant support to Allied campaigns in the Pacific and Southeast Asia. The war in these regions resulted in heavy losses for both the British and Japanese forces.
