Take the information from the scout

Help stalkers to free their friend who is being held hostage by bandits at Cordon's ATP. Take his flash drive to Sidorovich.
== Walkthrough ==
BUG WARNING: Talking to Wolf is necessary in this quest! See the #Bugs section.
Speak to Wolf and agree to help stalkers. Receive a bottle of Vodka and some ammo for your handgun.
Head out towards the [ train car shack]. There you will find Tolik who lies wounded in need of help. Give him a medkit (a spare one can be found by the dead body nearby, if you haven't picked it up earlier).
Cross the road and talk to Petrukha. Decide on whether you need stalkers' help at all. Note: it's probably not the best time to pick the document up from the soldier's body under the [ road bridge], as it starts another quest and spawns the sniper who can kill Tolik.
Attack and kill the bandits, then free Nimble. Talk to him and take his flash drive.
Head back and speak to Petrukha and Wolf, receive your reward. Give the flash drive to Sidorovich, and receive additional 1500RU from him. You can also threaten him in the next dialogue, and get a better reward (12x70 Birdshot ×30).
== Notes ==
* Technically, you can refuse to help stalkers, just like in vanilla.
* Petrukha can be ignored, you can just rush the ATP without talking to him.
== Bugs ==
* Skipping the initial Wolf's dialogue will break the game, as it spawns many quest-related static teleports across various locations and quests. The reason behind this dev decision is unclear.
* After this quest, Petrukha walks to the east campfire, passing by Kuznetsov and his soldiers. Make sure he does this while being offline, as they will fight, with the inevitable result being the death of Petrukha.
* On his way back to the Rookie Village, Nimble takes an erratic detour close to the southern military checkpoint, triggering a military assault on the village. The solution is the same as with Petrukha - get away from him so he doesn't aggro the soldiers, teleporting to his place while being offline.
