This is the walkthrough for the second Mission Gaberoun Part 2.
As you are noticing this map is huge.
Be sure to search officers for the intel you need to keep moving forward. Sniper nests are very helpful at spotting enemies as well as they allow you to mask your shots and take out multiple bad guys. If generators don't start sparking and banging then shoot them a few times with your silenced pistol.
Officers have increased sight and also give increased sight to lower ranking soldiers so take the officers in the tents out first.
Be sure to tag every soldier you see, they walk all over the place and someone you think isnt important could end up wandering over by you so tag everyone, the map is dark and there are always more guys than you think!
