Sierra 1

Sierra 1 is a two-man Central Security sniper team that appears in "Revelations", whose task is to support Alpha Team in securing the apartment complex in downtown Enderossi in the Katona Province.

Positioned on the adjacent rooftop from the target building, Sierra 1 assists in the neutralisation of several terrorists on site, granting Alpha Team 1 assess to the floors above. The fate of Sierra 1 after the fall of Atlanta Federation is unknown.
