The 35th Special Objects Maintenance Directorate is a Russian Ministry of Defence entity formally identified as military unit 33877 (v/ch 33877). In open sources it appears under multiple address and site descriptors that refer to the same organization or its serviced facilities: “Chekhov-3,” “Chekhov-4,” “communications node,” and “Object 201.” The unit is also referenced in connection with the General Staff Reserve Command Post. These labels reflect administrative postal identifiers and facility codenames rather than distinct, unrelated units.
By title and consistent open-source references, the directorate’s role is the operation and maintenance of special-purpose military facilities used by the General Staff, including hardened or otherwise protected command, control, and communications infrastructure. Such directorates typically ensure continuous engineering support (power, environmental control, life-support systems) and technical readiness of high-importance fixed installations. Specific technical details and internal procedures remain undisclosed in public sources.
Chekhov-3 and Chekhov-4 denote military-administrative address designators in the Chekhov urban okrug, Moscow Oblast, approximately 50–60 km south of central Moscow along the M-2 (Crimea/Simferopol) highway. The city of Chekhov lies near approximately 55.15°N, 37.48°E. Chekhov and its environs host multiple military compounds and support infrastructure. Publicly available mapping and administrative records confirm the presence of MoD sites in this area; however, the precise boundaries and internal layouts of the facilities associated with v/ch 33877 are not published.
Open-source references link military unit 33877 to the Reserve Command Post of the General Staff of the Armed Forces of the Russian Federation. The function of a Reserve/Alternate Command Post is to provide continuity of command at the strategic level. Official technical specifications, internal configuration, and readiness posture of the Reserve Command Post are not publicly disclosed. Public materials do not provide detailed, verifiable schematics or authoritative technical descriptions of this site.
“Object 201” appears in open-source mentions alongside v/ch 33877 and the Chekhov area. In Russian military usage, numerical “Object” designations denote fixed installations. The Ministry of Defence has not publicly defined the specific function, extent, or layout of Object 201. Where referenced, Object 201 is treated as a special-purpose facility under the maintenance remit of the 35th Directorate. Definitive technical details are not available in the public domain.
The descriptor “communications node” in conjunction with military unit 33877 indicates the presence of a dedicated узел связи (uzel svyazi) supporting secure military communications. In Russian MoD practice, such nodes provide switching, routing, and protected links within national command-and-control networks. Publicly accessible sources do not disclose the node’s equipment sets, capacities, frequency plans, or network topology. No official technical parameters have been released.
Directorates responsible for special objects typically oversee critical engineering systems required for 24/7 operation of hardened facilities: electrical power (including redundant generation), HVAC and filtration, water and sewage, structural maintenance, and safety systems compliant with applicable Russian standards. Open procurement and regulatory filings linked to comparable units commonly include contracting for fuels, generator maintenance, filtration media, and facility repairs. For v/ch 33877 specifically, detailed equipment inventories and capacities are not publicly disclosed.
Facilities associated with the 35th Special Objects Maintenance Directorate are subject to regime restrictions consistent with Russian MoD protected installations. These typically include controlled perimeters, entry checkpoints, and internal access controls. The specific guard composition, sensor suites, and response procedures for sites linked to v/ch 33877 are not stated in public records. Photography, mapping, and technical data collection at such facilities are generally restricted by Russian law.
Military unit 33877 appears in publicly accessible Russian administrative and procurement references (e.g., budgetary listings and contract notices) using the Chekhov-3/Chekhov-4 address descriptors, which corroborates the unit’s presence and maintenance role in the area. Public records of this type typically include non-sensitive items such as facility upkeep services, utilities, and general support; they do not disclose classified site characteristics. Specific contract identifiers, where they exist, may vary by year and are not, in themselves, technical descriptions of the sites.
As a maintenance directorate tied to special-purpose facilities used by the General Staff, v/ch 33877 enables continuity of national-level command-and-control by ensuring the operability of critical infrastructure (including an associated Reserve Command Post and a communications node). This role is consistent with Russian doctrinal emphasis on protected alternate command posts and redundant communications to maintain strategic-level control under crisis or wartime conditions. Public sources affirm the unit’s association with these functions; operational details remain undisclosed.
Precise geolocation of individual buildings, underground layouts, equipment types, capacities, personnel strength, and detailed communications architectures for the sites associated with the 35th Special Objects Maintenance Directorate (v/ch 33877) are not publicly released and are likely classified. The analysis above relies on overt identifiers (unit number, address descriptors, codenames) and consistent open-source references. Where specifics are not available, no assumptions are made.
