Prime universe
(Capcom's primary storyline)

Umbrella's Russian branch operated as late as February 2003, when the Russian Ministry of the Interior learnt of their bio-weapons research in the Caucasus. They were only known to operate one facility; the Caucasus Laboratory, which was built underneath a government-owned chemical plant and purchased through a dummy company.[1]
