The Umbrella Corporation [is] 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 paramilitary operations. They used a variety of vehicles, including HUMVEEs. Complementing this security force was an air wing, which maintained a fleet of AV-8B Harrier jump jets, UH-60 Blackhawks, C-130 Hercules water-landing capable cargo planes, CH-53 Sea Stallion cargo helicopters for transporting prisoners and Hughes MH-6 'Little Bird' attack helicopters. The corporation utilized these resources in order to secure and protect its assets, as well as its high profile employees.
