This one can be tricky. You must only use the Uragan-5 pistol as it’s a non-lethal weapon. A majority of this level is “on-rails,” and the helicopter flies on a predetermined path while you take a seat on the side providing covering fire for the undercover agent that’s making his way to the extraction point.

Eventually you'll have to hop off the chopper and make a run to the agent once he falls unconscious during the mission. When you reach him, be sure to grab the FB MR R-Launcher that's just behind him.

An armored vehicle will roll out from the main gates of the Admin Building. You won’t have to worry about killing soldiers that are inside the armored vehicle, but when you use the launcher to destroy the vehicle make sure you are clear of downed enemies that you have already neutralized with the pistol. Splash damage from the launcher will kill them.

Use the Uragan-5 pistol once more to get rid of the enemy within the opposing helicopter at the end.
