1. Perform a knife throw at enemy guard post
You will be prompted to do this after climbing a ladder near the start of the mission. Simply do as you are told to complete the challenge!
2. Survive an enemy RPG blast which causes enemy collateral damage
For this one, you need to take damage and survive an enemy RPG attack that kills an enemy. I recommend grabbing the flak jacket from the acces locker after dropping through the skylight into the first building. The place I was able to get this was in the same area as Noriega’s plane. There is an RPG on the roof opposite where you enter. Run over and stand near an enemy and hope that an RPG hits nearby to do what needs to be done!
3. Destroy Noriega’s private jet
In the same area as Noriega’s plane, you will find a MG truck. Jump on the back and shoot the jet until it blows up.
4. Eliminate enemy personnel (x10) with truck mounted MG
In the same area as Noriega’s plane, you will find a MG truck. After shooting Noriega’s plane up, kill 10 enemy soldiers with the MG to complete this challenge.
5. Destroy enemy ZPU (x1)
This is a tricky one to find. The ZPU is an anit-aircraft gun located on a rooftop. When you are escorting Noriega through the slum type area. Continue up the centre of the area when you reach a courtyard with a pair of RPG gunners up on the roof to the right, kill them and then look further to the right to find the ZPU. If you can’t find it, look for the building with 'GRAN Fras Herramienta' written on it. Just work your way around this building until you can see it on the roof.
6. Distract enemy personnel (x8) with Nightingale grenades at the same time
You can find the nightingale grenades after the firefight at the roundabout at the start of the level. Continue down the stairs behind the roundabout and look on the left hand side of the next area to find a container we can open for them. These grenades will make noises to distract enemies when thrown. Simply distract 8 enemies at a time with them to complete the challenge. A good place to attempt this is around Noriega’s private jet. Note that you can toss as many of these grenades as you like, just ensure they are all distracting enemies at the same time for it to count!
7. Eliminate enemy personnel (x15) with IR strobe
In the open city area whilst escorting Noriega, if you stay along the left hand side of the area you will find a wire gate to access that contains the IR strobe grenades. Toss these into a group of enemies to signal a quick missile strike. Once you have killed a total of 15 enemies inthis fashion, you will have completed the challenge.
8. Eliminate 8 enemies in the clinic
This challenge relates to the point during the level when you are inside the building and a scene plays showing you trying to help a fallen woman. Simply kill 8 enemies here to complete the challenge.
9. Collect intel (x3)
Complete the mission without dying.
