How to unlock the Heroic Rescue achievement in Operation Flashpoint: Dragon Rising - Definitive Guide
Story related objective in mission 8. You have to save at least one hostage I think. If all survive, you get the "perfect rescue" as well. This shouldn't be hard at all, as there aren't really a lot of troops. And the ones showing up, won't give you a hard time
