It is best to select the point to the east of Qarya Sakhra Ee as your landing site. This will make it easier for you to reach the village without being noticed. After getting close, use the binoculars and mark the enemies guarding the main path and patrolling the wooden balconies of nearby buildings. Start slowly moving towards the buildings in the higher part of the village. This will allow you to go past several guards, but sooner or later, you will have to eliminate a few of them. Try to use a pistol with a silencer and then Fulton the enemies, or at least hide their bodies.
The deployment plans that you look for are located in one of the buildings in the higher part of the village, namely in the one with a large flag on it. Be careful, because there is at least one soldier guarding the building. Enter the hut and examine the documents lying on the desk. It will make an enemy convoy appear north of your location. The convoy is heading to Da Smasei Laman.
Note - the convoy may also appear on the map after you rescue the prisoner in the village (you can read more about it in the chapter with the description of the optional objectives in this mission) and then try to get away from this location, or if you spend too much time on the map.
