There are several entities in Russia, including military and law enforcement agencies, that may have units referred to as "Otdel Spetsialnogo Naznacheniya." These units are typically highly trained and equipped for specific, often covert or special operations. It's important to note that the exact structure, names, and functions of such units may vary across different organizations.
More recently, some units of the Federal Penitentiary Service (Федеральная служба исполнения наказаний - ФСИН) or FSIN, have adopted pixelated camouflage designs to replace previously issued camouflage patterns. It would appear the designs are limited to Special Purpose Units (отряд специального назначения) or OSN.
