Special Activities Office
Identification
Most likely this record refers to the FSB's Управление специальных мероприятий (USM). Two independent open-source reference projects that track the FSB place USM inside the FSB Counterintelligence Service / First Service. Neither source, however, publishes a standalone facility address or coordinates for the office.

Location
Because no placemark is provided and no public source reviewed identifies a separate USM compound, the safest location assessment is a central-apparatus office in Moscow rather than a uniquely geolocatable base. Official FSB pages repeatedly list the service's Moscow address as 107031, ul. Bolshaya Lubyanka, dom 1.

Parent service
USM is publicly associated with the FSB Counterintelligence Service. Russian law defines counterintelligence activity as action by FSB organs to detect, prevent, and suppress intelligence and related activity by foreign services and organizations; Agentura's profile of the Counterintelligence Service additionally describes its contemporary scope as espionage counteraction, foreigner entry/exit controls, illegal migration, operational border cover, and operational search.

Site characteristics
Open sources reviewed for this brief describe USM as an office within the service hierarchy, not as a field base, training center, or separate garrison. No public source located for this brief identified dedicated barracks, heavy equipment, air assets, or a separate perimeter attributable specifically to USM.

Confidence
Confidence is moderate on organizational identity and low on exact siting. The hierarchy strongly matches the FSB's USM, but open sources do not publicly confirm a distinct building, coordinates, or site-specific infrastructure; any more precise geolocation would be inferential rather than verified.
