Stalcraft Wiki: Bulat-M Armored Suit

In-game description (EXBO)

A set of military gear, assembled for the escort group assigned by SSPP to the employees of Research Institute 7, who were conducting studies on the anomalous fog at the Sovkhoz. They say that some stalkers managed to acquire similar armored suits by assisting the institute's employees in their work. However, most of these likely ended up in their hands through trivial smuggling.
