Anomaly grenades

In return for his stock of attachments and explosives, Adrenaline wants us to retrieve the blueprints for anomalous grenades located by a certain stalker. They should be located in a backpack on the roof of a building in the Ironworks, since they had to ditch their loot after being chased by vehicles.
He will also contact Grizzled for his services, so we'll need to turn in 500,000 RU at the end of the quest.
Bring long-range turret removal in the form of the PTRD or Fenrir's Cheytac M200.
==Walkthrough==
The Ironworks has been reinforced with a full contingent of 40 Blackwater mercenaries, 12 turrets installed on high vantage points, and three APCs. Advance carefully through the area and clear each of the installations as you see them.
The stash itself is located on the south-central building roof, which can simply be scaled by a ladder at ground level. Look inside the broken vent and grab the backpack.
Shortly after picking it up, a light helicopter will spawn and harass you. Being able to quickly take it out with your turret removal weapon will be convenient, as another will spawn soon after, and another after that. After the third helicopter, you'll be free to return to Adrenaline with the blueprints.
==Notes==
* You may want to clear out the Ironworks before taking on this quest. Taking on all of the installations and the 40 additional Blackwater mercenaries on top of the already very populous map may drag things out quite a bit.
* Some of the Blackwater mercenaries spawn in the eastern wilderness where normal mercenaries don't usually go. They may engage the scientists if baited far enough forward.
==Bugs==
* Sometimes enemy turrets can be knocked over and clip through walls, making them impossible to take down without angling a grenade throw or getting closer to their elevated location.
