The Umbrella Security Service (U.S.S.), also known as the "Umbrella Special Forces", was a small and elite private Special Forces group owned and operated by the Umbrella Corporation. They reported directly to the highest ranking officers of the company and as the so-called "private police" of Umbrella, the unit was responsible for not only guarding Umbrella executives and protecting research facilities, but also took care of behind the scenes jobs that needed to remain secret. Unlike the U.B.C.S. which performed more visible missions such as rescuing civilians, this unit maintained total secrecy and a small size. Members of the unit were trained directly under the supervision of Umbrella on Rockfort Island.
History
The U.S.S. and its history is mostly confidential. They have been involved in operations throughout the world between the United States and Africa.
Plant 57 Clean-Up (1980s)
The U.S.S. was involved in the clean-up operation of Umbrella Plant 57 following an accident during testing of a new B.O.W., which caused the destruction of the factory. Working alongside the government, the U.S.S. eliminated any survivors and witnesses to the accident.
Ecliptic Express Investigation (July 23, 1998)
Delta Team of the U.S.S. was sent to investigate the Ecliptic Express train in the Arklay Mountains following the annihilation of the second investigation unit on-board. After gaining control of the train and reporting the situation, the team was attacked by the leeches and wiped out.
G-Virus Seizure Operation (September 15~23, 1998)
On September 15, William Birkin refused to give the completed G-virus to Umbrella. In response, an order was immediately issued by Christine Henry to Special Agent HUNK to lead Alpha and Bravo teams of the U.S.S. into Raccoon City to seize samples of the G-virus from Birkin. On September 20, the team performed recon of the city sewers. On September 23, Bravo team covered the sewer escape route while Alpha team penetrated the underground laboratory and detained Annette Birkin. HUNK and another member confronted William Birkin himself. In the aftermath, Birkin was shot and left for dead and a case containing samples of the t-virus and G-virus was obtained. However, Birkin had a sample of the G-virus on his person and promptly injected himself with it, mutating into a creature known as "G". The creature followed the team to the sewers, leading to a complete slaughter of both teams. The only remaining survivors were HUNK and Miguel, who escaped with a head injury.
A second U.S.S. squad led by Senior Captain Rodriguez was deployed to Raccoon City via helicopter during the subsequent outbreak. Almost every member of the squad except for Rodriguez were killed in the incident and became Zombies, and their actual objective and reasons for being deployed are unknown. Rodriguez decided to betray Umbrella and attempted to escape with the "Nyx" specimen, but failed. He successfully escaped the city via helicopter as the only survivor of the 2nd squad. HUNK managed to escape the city with a sample of the G-virus. It is not known if Miguel managed to escape the city.
