Umbrella Security Service™ Alpha

The Umbrella Corporation was a giant conglomerate which operated ruthlessly as a major international player in a number of markets including pharmaceuticals and medical equipment along with top-secret operations utilizing genetic engineering and biological weaponry. The company also had a more benevolent public face for the ignorant masses, producing cosmetics, consumer products and foods.
A subsidiary of Umbrella operated as a malevolent paramilitary organization. This division of the corporation maintained a highly trained security force capable of rescue, reconnaissance, and para-military operations.

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
