This is a new texture for mercinaries, i thought that their "police outfit" looks rather strange in forests and fields of the zone.
So this is the new ACUPAT camoufliage.
This skins are also work with the Stalker Call of pripyat and Shadow of Chernobyl.
Just copy the gamedata folder into youre root game folder.
You can use this skin in your own mods if you credit me.
