3 - Gate � Suggested way to enter the airport (a gate which needs to be opened). Once you've used this passageway head south to the building with the arms dealer (4 on the map).
4 - Arms dealer � The arms dealer can be found on the first floor of the building. Later on in the mission a CFA official will arrive here via a chopper (5 on the map).
You can listen in to the conversation between the arms dealer and the CFA official when they're visiting different parts of the airport. You can also stun and exfiltrate both of them (they're all additional mission objectives).
5 - Gunship � A gunship with a CFA official on board will appear in this part of the map and its destination is the airfield's main building (4 on the map). You can take down the gunship when it's still in the air and eliminate the CFA official that way (main objective) or you can wait for it to land and either stun him or wait for him to meet with the arms dealer (optional objectives).
The gunship itself should be shot down sooner or later, because you'll obtain a blueprint as a result of that (hidden mission objective).

6 - Containers � The containers are in the hangar and one of the hidden mission objectives is about extracting them. You can't do that until you've unlocked the Wormhole upgrade for the fultoning device.
