ERCS Guard

ERCS Guards are people who are employed by the Elanus Risk Control Services company. They are typically armed with either Assault Rifles or Shotguns.

ERCS Guards are employed on Noveria and are the only ones allowed to carry weapons while on the planet, apart from Spectres. The Noveria Development Corporation gets a discount for their services, and since they are the only ones allowed to carry weapons, they are constantly being, or trying to be bribed by the various corperations that rent Noveria's labs. The captain of the guards, Maeko Matsuo, has a strict policy against that, and will take action if she finds any of her guards taking bribes.

When Commander Shepard travels to Noveria during the search for Saren, the guards, and Ms. Matsuo aren't happy that Shepard and the squad get to keep their weapons. However becuase of the arraingment between the Citadel Council and the NDC, they have little choice, so Captain Matsuo lets Shepard pass but asks that they please not use them.

While Matsuo is against bribes, some of her guards take some bribes from Administrator Anoleis to raid the local Synthetic Insights, Ltd. office to get information that exposes his actions. Shepard can talk to Lorik Qui'in to get into the office and recover the information. However Shepard can also turn the info over to Anoleis, either way results in Shepard getting out of Port Hanshan.

If Shepard breaks into the office, the local guards attack and eventually Sgt. Kaira Stirling confronts Shepard. All the guards and Stirling die fighting Shepard and the squad, and they can be reported for their actions.

Tactics
ERCS guards are just like ordinary Mercenaries in both tactics and defenses. However becuase you are fighing in a confined space, using biotics and tech attacks to weaken their shields and overheat their weapons is a good tactic. They like to sty on the move, so stay on the move yourself to avoid being flanked. Overall, keep moving, keep shooting, and use talents to put them down for good.
