U.S.S. Delta Team (Wolfpack)

The U.S.S. Delta Team - informally referred to as the "Wolfpack" - was an elite squad of covert operatives employed by Umbrella Security Service, the paramilitary wing of the Umbrella Corporation. In the aftermath of the original unit's destruction, Umbrella formed a new Delta Team consisting of six members: LUPO, FOUR EYES, BERTHA, SPECTRE, BELTWAY, and VECTOR. In late 1998, Delta Team was dispatched by U.S.S. Command to infiltrate Umbrella's Raccoon City Facility; their orders were to assist HUNK's U.S.S. Alpha Team in their mission to retrieve a sample of the G-Virus from Doctor William Birkin, a rogue scientist who betrayed the Umbrella Corporation by attempting to sell his creation to the federal government of the United States. However, Delta Team was forced to retreat from the facility after Birkin injected himself with the G-Virus while HUNK remained behind in order to complete the mission.

A week later, Raccoon City was accidentally contaminated by the Corporation's t-Virus, thus forcing Umbrella to deploy Wolfpack into the quarantined area with orders to commence Operation Raccoon City. The failure to contain the outbreak placed Umbrella in a precarious situation for if the world ever learned of their involvement in the destruction of Raccoon City, as well as their research in bio-weaponry, the backlash would almost certainly destroy Umbrella Corporation. To ensure Umbrella's survival, Wolfpack was charged with destroying all evidence that could encriminate the company, including civilians and R.P.D. officers because any survivor was also an eye witness, and thus a potential threat to Umbrella's existence. At the same time, the U.S. government sent a detachment of armed troops to enforce the quarantine of Raccoon City and to ascertain the nature of Umbrella's involvement in the contamination of the area. As a result, Wolfpack fought and killed numerous American soldiers throughout the course of their mission.
