Fire support

Kostya asks you to support his old friend Warg on an assassination mission in Agroprom. Your role is a spotter, while Warg will be sniping. The target is a former stalker protected by the military. The mission has to be done without the unnecessary fighting, otherwise the target will be alerted.
Kostya also warns you to put your weapon down when approaching Warg.
This quest has a card from Kuznetsov's deck.
This quest is partially unmarked.
== Walkthrough ==
=== Meeting Warg ===
Head over to Agroprom. You have to enter from the Dump; Kostya mentioned two BTRs which protect the VIP target, their location is shown on the picture below.
To avoid their line of fire, you'll have to make a detour to the north, as shown on the picture.
Warg can be found on the roof of one of the central complex buildings marked on your PDA map; he will not spawn until you make it to the roof. Before doing that, you might want to wipe out the bandits that camp above the Agroprom Underground entrance, to avoid them killing Warg.
Put your weapon down (as Kostya told you), and talk to Warg. He will tell you his plan:
* The target is usually on the third floor, only going out to a roof of the military base for a smoke. This is the perfect time for the shot; you'll need to confirm the target for Warg.
* After eliminating the target, Warg will leave through the [ tunnel] to the Cave.
* You should destroy the APC blocking the exit to Dump, with the RPO-A he will give you, then take the position on the [ watchtower] and cover Warg while he's escaping.
* Then leave to the Dump.
Warg will give you an RPO-A to be used later. After a cutscene (you can watch the military base through your binoculars if you want), he will take a shot, killing the target.
=== Retailation attack and retreat ===
A military patrol will spawn underneath. Kill them. One of the soldiers will have the playing card from Kuznetsov's deck on his body.
Move out of the complex, and blow up the BTR covering the Dump exit using the RPO-A Warg gave to you, or any other available method.
=== Holding back the pursuit ===
Head to the watchtower to cover Warg's retreat. Make sure to save before doing this, since leaving the tower at any point before his escape will fail the quest, and keeping him alive is also going to be difficult.
Several more special forces soldiers will spawn around the area, approaching from both the south and west. West direction is more important since Warg will attempt to leave the complex from there. Shoot at the soldiers at the south as well just to draw their aggro; this will prevent them from ignoring you and getting into position behind the trees.
Eventually Warg will leave through the tunnel to the Cave. You can descend the tower and leave the area in any way you like; you'll probably want to stick around to pick up the playing card and loot from soldiers regardless. Be also sure to blow the second BTR up, as it won't despawn on itself.
=== Back to Kostya ===
Return to Kostya for SVD "Tiger" which is a strong sniper rifle that makes very efficient use of common and cheap 7.92x57mm cartridges. 
After turning in the quest, Sidorovich will message you to come see him, starting the Leshy questline.
==Notes==
* The visibility from the watch tower is bad. You may want to use the BPOs binoculars or a rifle with target recognition. A powerful rifle is also recommended; a 5.45 rifle requires three headshots to down them, a 7.62x51mm rifle will need one headshot, and a .338 rifle will take them down in one body hit.
* Another risky strategy if you can't take out the soldiers from the south in time is to expose yourself on the outside of the watchtower to take aggro from the soldiers below, then retreat to the inner part with cover.
* You aren't forced to use the RPO-A given to you by Warg.
==Bugs==
* This quest can somewhat conflict with The defense of the complex which spawns additional BTRs; it's easy to destroy the BTRs from this quest before speaking to Warg, violating Kostya's instructions to not alert the military. As the quest is not tracked at this point, you can easily softlock your game if you forget about it.
