The Umbrella Corp. was divided regarding the Racoon City infestation.

* Virologists within the city limits spent their time researching a cure.

* Weapons researchers had experimental Bio Organic Weapons (B.O.W.s) sent in, in order to gain data on their effectiveness at killing civilians.

* And the Umbrella Biohazard Countermeasure Service (UBCS) was sent in to evacuate civilians.
