Mission 12 Contingency
At the end of the forest section, you will have to eliminate 3 enemies and two dogs. Then, run ahead of Price and head down the hill before he instructs you to use the predator drone. If timed correctly, the anti-air vehicle will be destroyed before your predator drone spawns in. Price will say something if your predator drone is destroyed. This can be a bit fidgety, so reload checkpoints as needed.
