Hello, soldier. What are you interested in? Cash? Goods? Ah, you want a job... Sure, I'll give you a job... After you show me who you are and what you're made of. It’s the first time I see you and no offense, I don't give important tasks to everyone. Show me how tough you are in the field. If you can handle it, then you'll have cash, better goods, sweeter prices, well, you get me. Logical enough, right? Well, fine. Listen for your test assignment then. There are tons of bandits on Customs, roaming all over the area. Calm down, say, five of those parasites and grab a pair of MP-133 shotguns from them. Going to be your debut. Well, get down to business, soldier! Dismissed.
Enter the map Customs and search for and kill five Scavs whom can be found throughout the map. Be sure to check if they have the MP-133 12ga shotguns. This shotgun can be found on Scavs, inside various Searchable Containers, or simply lying around. They must be in a functional state to be handed in. To hand over the shotguns, go to the Traders menu, then to Prapor and click on the "Tasks" tab. Here you should see the "Turn In" button to hand over the shotguns.
