International research group of S. T. A. L. K. E. R for GTA San Andreas

International study Group (IIG) is a carved group, sponsored by the UN. IIG previously appeared in the story of S. T. A. L. K. E. R.: clear Sky on location Generators. Although she was cut, her reference is still preserved in the ERS. A mercenary named Hogue can tell major expedition to the Area arrived, and says they're definitely not scientists: a soldier per kilometer in sight. Apparently this group was very similar to mercenaries, and their main purpose was some secret order from the UN to find something in the center of the Zone. All members of the IIG had armor in the form of changed overalls Monolith (common and scientific, with slightly changed colors and new badges). Weapons used only by NATO, most TRS-301.
