Umbrella Corporation

The Umbrella Security Service (abbreviated "U.S.S.") was an Umbrella elite special forces taskforce. As opposed to the UBCS, who were mainly used for "Cleanup" work, the U.S.S. were specially trained "black ops" unit dispatched by Umbrella.

The Rockfort Island Military Training Center, trained recruits to Umbrella's paramilitary taskforces until the island's capitulation in December 1998. One of the most well known members of the U.S.S. forces "HUNK" was trained there in 1996.[1]

History
The first known assignment of the U.S.S., was the order placed for the assassination of Dr.James Marcus. increasingly paranoid over Marcus's research, Oswell E. Spencer ordered his colleague's execution.[2] While not sporting their later comrades' trademark gas masks, the unit did share similar tactics employed in September 1998, namely the operation in two-man cells. Their armament of MP5 submachine-guns was also echoed by later units.
The next, confirmed, implementation of the U.S.S. was on July 23, 1998. Albert Wesker, an Umbrella researcher; former security officer and current (at the time) police infiltrator, was tasked with the re-opening of the Umbrella Research Center,[3] which had been abandoned since Marcus' death. With both the first and second investigation units compromised by an unexpected t-Virus outbreak, along with the Ecliptic Express, a private intercity train ready to take Umbrella personnel for management training, the U.S.S.' "Delta Team" was called in to investigate. Following Wesker's orders, the two-man team took control of the engine and starting it up again. At its speed when radioing to Wesker, the train was ten minutes away from the training facility's station. However, the team was attacked by a horde of infected leeches and the two men taken down. They would be reanimated as zombies minutes later.

Later that year in September, Umbrella became concerned over Dr. William Birkin's development of the G-virus, a mutagenic toxin set to replace the t-Virus. Intent on selling the virus over to the US Government for a military application, the U.S.S. was quickly called in to Raccoon City to abort any proceedings. On September 20, police officer Carl Nielson filed a report after encountering an individual skulking through the sewers. Although unable to catch up to the man to question him, Officer Nielson did stumble onto military-grade weaponry such as C4 plastic explosives with a detonator, and a broken infra-red scope for customizing firearms.[4]

Not long after, the two-man "Alpha Team", lead by "HUNK", trapped Birkin in his lab. With orders to retrieve a sample of the virus, the U.S.S. unit gunned down Dr. William Birkin and left with samples of the G-Virus (HUNK is actually seen here calling in the success of the mission). Leaving in a hurry to avoid detection, the two failed to notice Birkin carrying another sample of "G". Injecting it into himself, he mutated into a frightening monster ready for revenge. Several U.S.S. teams in the sewers composing of at least eight men were swiftly executed by the renegade doctor, with HUNK barely escaping alive.

Fully regaining consciousness on September 30, HUNK made his way out of the sewers and to the Raccoon City Police Department's helipad, and successfully escaped the city.

During the outbreak, the 2nd U.S.S. Squad was tasked with removing the experimental weapon Nyx from the city. The commander, Rodriguez, went rouge and attempted to steal the bio-weapon after the rest of the squad vanished. A UBCS team under the command of Arnold and under the supervision of Tommy Neilson was dispatched to capture him. Despite the nearby area being mined, Rodriguez escaped by helicopter, but lost Nyx in the process.

The last known usage of the U.S.S. was in November 1998 when a small U.S.S. team lead by HUNK was assigned to transport a container to Rockfort Island. The mission was controversial in that Alfred Ashford, the island base's commander, did not reveal to the team exactly what was inside the crate - HUNK was concerned over the danger of an unidentified package, that could put him and the rest of his unit in danger.

Arsenal

The standard weapon used by the U.S.S. in Resident Evil 2 is the Heckler & Koch MP5 Sub-Machine Gun. Although they have been known to use other weapons such as pistols, with HUNK having his own special handgun, which he nicknames Matilda.

In Resident Evil: The Darkside Chronicles, the U.S.S. standard MP5 is replaced with the Steyr TMP. Also, judging by the inscription on the barrel of the Custom Magnum Parts found in Resident Evil 2, the U.S.S.'s armory also contained some heavy, albeit impractical firepower; a 10-inch version of the IMI Desert Eagle semi-automatic magnum handgun chambered in .50 Action Express—when or where it could have seen operative use is unknown.

U.S.S. 2nd Squad leader Rodriguez is seen with a Remington M870 in concept art, although he holds an M4 during gameplay.
