The British Islands (abbreviated as BRI) are one of the 12 divisions of the Earth's Government in Mega Man X: Unit 49. The territory comprehends the group of islands with the same name, the British Isles. It is ruled by the councilor Alain, with London as capital. Has the highest quality of life of all the divisions and also possesses a great technological pole. It is home to the main facility of the Research and Development of Reploids Bureau and thus is responsible for most of the technological breakthroughs in the last years.
During the Great Repliforce War, Storm Owl's fleet passed over many cities of this division on their way to the Spaceport. Some ships committed excesses and shot their laser cannons, hitting civilian buildings and causing destruction through the Cambridge District.
