Once the Evidence Recovery Entry Strike Teams complete their mission, there are several possible CRBNE CSIU Group operations that may be required in order to complete the crime scene investigation. ¨ese operations will be dependent on the nuances of each CBRNE/TIC crime scene. ¨ese operations are the search entry and the žnal survey entry. ¨e same operator, Facilitator, and D/A member methodology previously described in the Aseptic Techniques section, will be used by three-person strike teams for both of these entries.
