Reconnaissance by fire

Screw wants you to find heavy vice at Ironworks. The problem is that he doesn't know any safe route from Swamps there. He advises to check Devotee out first, as he might know something about the mercs coming from Ironworks through Swamps and Cordon.
== Walkthrough ==
Move out to Cordon, and talk to Devotee. Complete the Arc of Fire quest for him; you'll obtain the transition to Ironworks in the process, and also two PDAs you need to give Screw.
Travel to Ironworks through Swamps. As Devotee warned you, there's a lot of mercenaries on this location, and they set up turrets there. Potential approaches to turrets and mercenary APCs are shown on the picture.

Two mercs will carry M60s.
The vice for Screw (15kg) can be found inside the [ production facility]. After picking it up, a light helicopter will fly in. Destroy it by targeting the pilot. Alternatively, it's one hit to the body with PTRD.
Return the vice and both PDAs from Arc of Fire to Screw for your reward.
== Notes ==
* After finishing this quest (reporting to Screw) a fugitive named Coyote will spawn in the [ abandoned village], if you accepted Rabbitfoots. He's a part of that quest you likely already forgot about, and has a playing card from Kuznetsov's deck on him.
