I did a little of backtracking but couldn't find it. From what i understood in their speech, i need to find someone that has an orange vest. Can any of you who went past this already tell me where i can find this guy?
Okay, the second ID Mission, just look around and tranq everyone you see. You'll find the soldier in the orange vest. He's two areas away from the goal, or three, if memory serves me right. I think he's in the area with the most guards. And if you have to, use the Analyzer, it'll display the ID in the Item List when you scan the orange vest soldier.
