The Umbrella Biohazard Countermeasure Service (U.B.C.S.) was a private military force owned by the Umbrella Corporation, specializing in rescue operations during biohazard outbreaks. It was founded by former Soviet Colonel Sergei Vladimir. The U.B.C.S. primarily recruited former soldiers and militiamen who had been incarcerated and, thus, could be offered a new life. At its largest in 1998, this force consisted of at least four platoons, designed Alpha through Delta, making for a complement of as many as 120 mercenaries. It suffered near total destruction during the operation in Raccoon City.

Over the course of the 1990s, Umbrella's t-Virus Project advanced through to Phase 3 of its development and production of working prototype Bio Organic Weapons was taking shape.[1] Due to the serious health and security risks posed by escape prototypes, Umbrella sought the establishment of a dedicated anti-B.O.W. force distinct from the Umbrella Security Service. These mercenaries would then be provided with experimental antiretroviral drugs to limit the risk of an outbreak among the unit during an incident.[2] Umbrella scouted around the world for recruits, ranging from retired Soviet Army officers to terrorists prisoners on death row. With the end of the Cold War, these recruiters had a number of successes recruiting from former Warsaw Pact nations and the former Soviet Union.[3]

Over the course of 1998, a series of t-Virus outbreaks in the Arklay Mountains drew the attention of Umbrella. This began with acts of sabotage at facilities in Raccoon Forest in May, resulting in the virus slowly spreading across the region. After three months the virus had made its way into Raccoon City with isolated reports of "monsters".[4] After a week this escalated to a recognised public health matter and Raccoon General Hospital was under lockdown due to increasing numbers of inpatients suffering from Cannibal Disease.[5] Owing to this and concerns with the local Umbrella leadership, the U.B.C.S. was placed on stand-by on Tuesday 15 September.[6] In the evening of Tuesday 22 September, the USS raided the Umbrella Chemical Plant on the edge of Raccoon City, intent on recovering the experimental G-Virus in the NEST laboratory complex beneath. The raid backfired, leading to a chain-reaction of events resulting in the contamination of the Victory Lake reservoir with ε strain by the start of the following morning.

Raccoon City deployment[]

On Thursday 24 September the US government placed Raccoon City and the surrounding area on quarantine, matched by the declaration of martial law by the Raccoon Police Department within the city. In collaboration with the Pentagon, the U.B.C.S. was allowed within the quarantine zone to aide in the rescue of civilians. Having had days or weeks to plan for an outbreak scenario, the platoons were tasked with a number of missions to accomplish, such as securing Umbrella facilities and recovering high-priority assets. Monitors within the force had additional orders to destroy sensitive data, recover prototype B.O.W.s, destroy facilities of danger to the company,[7] and record the outcome of fighting between the U.B.C.S. and the mutants.[7]

U.B.C.S. fighting reached its most extreme on the evening of Saturday 26 September as squads were dropped into the city centre which was already indefensible.[2] At least one was wiped-out within moments of dropping from their Aérospatiale Puma.[8] Cpt. Mikhail Viktor's Platoon Delta, which had orders to seize St. Michael Clock Tower as a rescue station, took heavy casualties and its survivors separated across the city.[9] Viktor himself was wounded in the streets and was sheltered on either a tram or subway train with several others, including Sgt. Nikolai Zinoviev, one of the Monitors.[10] Several mercenaries were successful in seizing the clock tower, but were unable to call for evacuation. Wounded mercenaries were looted for their ammunition, and civilians were used as human shields to protect the surviving mercenaries. The last of these mercenaries died on Monday 28 September when the clock tower was taken over by Giant Spiders.[2] Viktor's team collaborated with former S.T.A.R.S. police officer Jill Valentine in planning an evacuation, with accounts differing as to if they were headed to the clock tower or out of town directly. During their stay they were spotted by the experimental Nemesis-T02, sent by Umbrella to assassinate Valentine and which saw those around her as secondary targets. Zinoviev, aware of this, made his escape and the vehicle was destroyed following a suicide bombing by Viktor when the Nemesis made its move. Cpl. Carlos Oliveira remained with Valentine to nurse her back to health after being injured and infected by the Nemesis, and they renewed efforts to escape the city on the early hours of Thursday 1 October, ultimately escaping via a helicopter.

While Viktor's band believed themselves to be the only remaining survivors, there were scattered forces still active around the city over the course of the week. In one apocryphal account, a squad was sent out by truck to rescue Dr. Cameron, an Umbrella researcher they soon learnt had mutated out of control in a failed attempt to cure her Cannibal Disease. Cameron maintained her consciousness, and massacred the squad to prevent being detained as a test subject.[11] Clint's squad had orders to maintain control of the dockyards Umbrella was using, and were provided with life jackets accordingly. A squad led by Arnold held out for most of the week, taking advantage of the chaotic US Army retreat to seize their checkpoints; he was known to hunt Zombies with a sniper rifle from the highway overpass while his men lay down mines on the surface. Zinoviev briefly led a squad at Raccoon University as part of Operation: Emperor's Mushroom, where they had orders to recover a blood sample from the experimental Thanatos;[12] this team was wiped out during the engagement, though Zinoviev succeeded in assassinating its rogue creator and destroying the data in an explosion before fleeing in search of a helicopter.



UBCS unit as seen in Outbreak series.

In keeping with their important and dangerous role in anti-B.O.W. combat, U.B.C.S. mercenaries wore military-grade tactical gear. The standard uniform consisted of black combat boots; beige-colored fatigue pants; a green fatigue shirt, webbing over the shirt to carry equipment, and a black balaclava and tactical goggles. The U.B.C.S. emblem was imprinted on the back of their uniform as a further means of identification. Individuals had freedom to customise elements of uniform such as shirt length. Only officers are known to have worn the U.B.C.S. green beret. Mercenaries working near water were provided with orange life jackets carrying the U.B.C.S. insignia.

Some mercenaries are known to have carried their pistols in drop-leg holsters, whereas others used a cross-draw holster attached onto their webbing.


The U.B.C.S. were provided with a variety of weapons and equipment as expected of a well-funded private military force. There was no one single standard weapon for mercenaries, and while those with special training were provided with weapons to match ordinary mercenaries also showed variety in their weapons. Such variation in standard rifles include the M4A1, Colt Model 727 and Colt Model 933, with sidearm options including the SIG Pro SP2009, SIG P225, STI Eagle 6.0,[13] Glock 18 (in both single and burst-fire models) and the Makarov PMs. H&K MP5A2s were used during Emperor's Mushroom to fight Thanatos, while Benelli M3 shotguns were available in the search for Cameron. Mercenaries were also provide with Mk3A2 concussion grenades for immobilising large groups of Zombies. For dedicated purposes, the H&K PSG-1 was available for snipers, and was used by Zinoviev and Arnold. AT-4 anti-tank rocket launchers were also available though rare.

The standard means of transport for the U.B.C.S. was the Aérospatiale Puma, a twin-rotor helicopter with a capacity for 16, allowing for two to three per platoon. Specialised humvees were also driven into the city, armed with Browning M2 .50 caliber heavy machine guns.

Further notes[]

  • In Resident Evil The Umbrella Chronicles, Umbrella's forces are seen being transported by a variety of aircraft including UH-60 Blackhawk helicopters.
  • The APCs featured in Outbreak resemble M8 Greyhounds. This is strange because M8s are quite old APCs dating back to the Second World War, though it does remain in service in some countries.
