The mission's objective is to score 20 kills using AUG. The rate of fire of this weapon is high and additionally, it has a good zoom, which makes aiming easier. The first 3 bullets fly directly towards the target, but above that, they tend to travel up, to the left and then to the right. To compensate for the tendency to travel, you have to counter it, i.e. pull the weapon down, then to the right and then to the left. Below, 2 interesting spots to set an ambush have been presented.
The pillars provide good cover and additionally, you can shoot between them to the opponents that may appear up in the distance. By leaning left, you can keep an eye on the spot where the bomb has been deployed.
Possibly the best spot on the entire map. The building provides very good cover from enemies, and you can keep an eye on 3 passages from here. The first one is to the left, right behind the tables. Another one is under the arch of the white building, where as the last one is on the right. After you back up a little, you will find a platform, from which you can fire in the direction shown in the previous screenshot.
