The Umbrella Biohazard Countermeasure Service, or U.B.C.S., is a private military group operated by Umbrella. U.B.C.S. exists primarily to control the disasters caused by Umbrella’s products and is always first on the scene of any accident.

Because of the dangerous nature of this work, many of the members are war criminals, refugees or others recruited with the promise of being pardoned from death sentences or life imprisonment. These soldiers often come from the armies of communist countries and possess a solid military background.
