Gunfire (or gun-fire) is a British caffeinated alcoholic drink, a cocktail made of black tea and rum.

[1][2][3] It is unknown when gunfire was concocted, but it is known that it was mixed by British Army soldiers during the 1890s.

During the Korean War, members of the American Military Police Corps were given gunfire by British soldiers under the guise of it being normal tea after a recovery mission.

This led to intoxication of the MPs who then drove an armoured recovery vehicle and some army jeeps into a camp gate as a result.

Gunfire was served to participants of British reality programme, Bad Lads' Army by the non-commissioned officers before their passing out parade, mirroring the same procedure in the British Army.
