On the PDA's faction screen, enter UP, DOWN, UP, DOWN, LEFT, RIGHT, LEFT, RIGHT on the D-Pad. You should hear a click that signifies the code is active. The merc will be invulnerable to all sources of damage (you may have to Medivac if you fall into deep water). This also applies to the current vehicle the merc happens to be operating at the time.

Go to the PDA's faction status screen and enter the following on the D-pad: RIGHT, LEFT, RIGHT, RIGHT, LEFT, RIGHT, LEFT, LEFT. A soft click should confirm the code's activation.

• UH60 Transport - The $ Challenge southwest of the DMZ (the AN HQ is in the DMZ area on the map).

• UH60 Transport - Northeast of the DMZ. This chopper becomes available after the Ace Of Clubs contract is resolved successfully.

• LHX Chopper - Inchon. This chopper is available after the South Korean mission involving the missile trucks at Inchon is resolved successfully.

• WZ-9 Chopper - Pyongyang Airport. This chopper is available after the Chinese mission involving Nampo is resolved successfully.

• NK Transport - North of Changsong Train station's eliptical road there is a small rise next to the restricted airspace with a ZSU and a chopper on it.

• NK Gunship - East of Changsong Train station there is an eliptical road. Head east from it and a small airbase can be found with several gunships and SAM carriers.

• Coaxial Gunship - This is a unique chopper that can only be found during the second Russian mission while verifying the Spades. The temple northwest of the Industrial Zone has the chopper, along with one of the mission's objectives.

• AN Gunship - This takes a little work. You also need a sniper rifle. Head to the east entrance of the Kusong MASH and climb the surrounding hills. A random set of gunships and transport choppers hover over the MASH (if you do not see a gunship, you can save/load your game). Snipe the pilot of a gunship as it passes over the MASH; the resulting accident will usually leave the gunship in barely flyable condition, and cost you $25,000 (for killing the AN pilot).
