District Guard

District Guards are turians that were hired by Aria T'Loak to guard the quarantine zone on Omega.

Overview
After speakin with Aria about Mordin Solus, Shepard heads to the quarantine zone where he is confronted by a district guard. If Shepard uses Charm or Intimidate, Shepard will not have to fight the district guards. However, if Shepard fails to convince the guard to radio ahead, the guards will open fire upon Shepard's arrival.

Tactics
The district guards have no armor or shields but make up for this by taking cover frequently. Wait until they are out of cover to take your shots and they shouldn't be too difficult to deal with.
