An assault on Umbrella's Russian branch that occurred in February 2003. A private anti-biohazard unit, of which Chris and Jill were members, obtained information on the development of a new B.O.W. (Bio-Organic Weapon).
The assault was later renamed to the T-A.L.O.S. Counter operation. Wesker, who had deliberately leaked the information, also infiltrated the laboratory, and absconded with Umbrella's entire research catalog.
