World War II: The end of fighting in the Battle of Hill 170 during the Burma Campaign, in which the British 3 Commando Brigade repulsed a Japanese counterattack on their positions and precipitated a general retirement from the Arakan Peninsula.

The Battle of Hill 170 was a battle between the British 3rd Commando Brigade and the Japanese 54th Division during the Second World War. The battle was fought in January 1945, as part of the Burma Campaign.

The Burma campaign was a series of battles fought in the British colony of Burma as part of the South-East Asian theatre of World War II. It primarily involved forces of the Allies against the invading forces of the Empire of Japan. Imperial Japan was supported by the Thai Phayap Army, as well as two collaborationist independence movements and armies. Nominally independent puppet states were established in the conquered areas and some territories were annexed by Thailand. In 1942 and 1943, the international Allied force in British India launched several failed offensives to retake lost territories. Fighting intensified in 1944, and British Empire forces peaked at around 1 million land and air forces. These forces were drawn primarily from British India, with British Army forces, 100,000 East and West African colonial troops, and smaller numbers of land and air forces from several other Dominions and Colonies. These additional forces allowed the Allied recapture of Burma in 1945.

United Kingdom Commando Force (UKCF), previously called 3 Commando Brigade, is the UK's special operations-capable commando formation of the Royal Marines. It is composed of Royal Marine Commandos and commando qualified personnel from the Royal Navy, British Army and Royal Air Force.
