Find documents of the military

Marked One needs to steal a case with documents from the military base at Agroprom, and bring it to Barkeep.
== Walkthrough ==
=== Guard schedule ===
Before attacking the base, you can visit Deserter in his shack on the swamp, and ask him about the base. Just like in vanilla SoC, he will give you the schematic of military patrols around the base at night. However, making use of it by sneaking into the base is difficult in OP-2, as NPCs are much more perceptive and Sherstyuk is sleeping in the base at night, and you don't want to run into him.
=== Dealing with helicopters ===
After killing any of the soldiers inside the base (except for the watchtower guards), two backup helicopters will arrive from the east. They are invulnerable until they unload their troops, so don't bother trying shooting them till then.
If you aren't sure you can deal with them, you can hide from the helis in the [ factory complex] or the train tunnel. They will fire several rocket salvos at you and will leave the location after several minutes. Alternatively you can try downing them; aim for the tail rotor for an easy kill. With some skill, they can be downed in 10 seconds after flying off their landing zones, with 1 magazine of your AKS-74U you got for finding the Lost document.
=== Attacking the base ===
Wipe the base out and grab the military case on the third floor of the research institute. As you grab the case, more soldiers spawn, and another heli will arrive from the south. This one is vulnerable immediately, and it passes very close to the building, so it's easy to take it down by running to the roof and firing at its tail rotor.
Don't forget to grab the Agroprom-Cordon transition on the same floor as well, it looks like a document.
After grabbing the military case and passing the Agroprom tunnel on your way to the Dump, you hear an incoming radio transmission and Grizzled appears in his personal helicopter. He's a flying trader, and will buy your scrap for cheap.
=== Escaping Agroprom ===
Proceed to Dump. As you approach the Duty checkpoint, you'll hear a call for help from Prapor - several boars are approaching from Dark Valley, and they need an extra gunman. Try to kill all of the boars before they reach the checkpoint since this results in a sizable reward. Regardless of your help, Prapor will open the gate and you're free to travel to and from the Bar.
=== Barkeep ===
Once at the Bar, give the case to Barkeep for your reward and the next quest in Dark Valley.
== Changes ==
After grabbing the case: Adrenaline appears in Agroprom. Artyom the Cook and Vityok the Raven appear in Dump. Wolf moves to Army Warehouses.
== Notes ==
* Sidorovich also warns you about the warrant officer, Sherstyuk. He tells you not to attack at night, because Sherstyuk sells military property to the side and might come useful (he's actually one of the major quest givers). Sherstyuk spends his nights inside the military base and is hostile from 10:00PM to 6:00AM. However, by day he can be found under the power tower near the base, and can be approached just fine.
* While Grizzled's prices aren't very good, you can unload any <10% condition guns on him for some quick cash. This will be helpful to have early on in the game.
* The case is 8.6kg, make sure you have some spare weight in your inventory to lift it.
