The Umbrella Biohazard Countermeasure Service (U.B.C.S.) was a private paramilitary force established by Umbrella to deal with any biohazard accidents caused by virus leakage and possible terror attacks from their opposing organization, and were always first on the scene to any accident. More than half of the members were mercenaries, including many ex-soldiers who were thrown into jail for some reasons, and due to this they are usually ordered to carry out extremely dangerous missions. 1
History
The U.B.C.S. was founded by Sergei Vladimir, whose experience in military affairs made him instrumental in the founding.
Raccoon City Incident (September 15~October 2, 1998)
On September 15, Umbrella issued a pending dispatch order to the U.B.C.S. to rescue civilians of Raccoon City. The exact reasoning is unknown, but believed to either be related to the rising t-virus epidemic in the city or a precaution in case of a biohazard caused by the potential failure of the U.S.S. to seize the G-virus. On September 23, a mass outbreak of zombies occured due to the leak of the t-virus in the city sewers caused by the failure of the U.S.S., and the condition of the city began to swiftly deterioate.
On September 26, all 120 members of the U.B.C.S. were dispatched to the city, arriving at sunset. The members of the force were unable to cope with the Zombie hordes, and were quickly overwhelmed and scattered.
Hierarchy
The U.B.C.S. was an unconventional unit, about the size of a company (120 soldiers) and consisted of four platoons (30 soldiers each) named Alpha, Bravo, Charlie and Delta, each one commanded by a Captain (Platoon Leader). Each platoon consisted of three squads (10 soldiers each) named A Squad, B Squad and C Squad, each commanded by a Sergeant (Squad Leader), and each squad consisted of two teams (5 soldiers each). These teams were named Alpha, Bravo, Charlie, Echo and Foxtrot.
Members of the force who did not directly approach Umbrella and request to join were generally scouted by "Mercenary Coordinators" and offered an ultimatum of freedom from their life or death sentence in exchange for joining the force.
