What are S.T.A.R.S.?

S.T.A.R.S. stands for Special Tactics and Rescue Squad and is a investigating unit that the main characters all belong to. S.T.A.R.S. does not provide backup to the Raccoon City team after the Spencer mansion fiasco because Umbrella blackmailed or bribed key members of the organization. David and Barry are furious at S.T.A.R.S.'s betrayal.
