Location Analysis
Ussuriysk is a major transport node on the Trans-Siberian Railway and the A-370 Ussuri Highway, approximately 100 km north of Vladivostok. The city hosts extensive garrison infrastructure and railheads supporting the reception, staging, and onward movement of personnel and equipment. The army’s area of responsibility covers Primorsky Krai and adjacent sectors of the southeastern Far East, providing ground defense depth toward the Sea of Japan and the borders with China and North Korea.
Armored and Mechanized Capabilities
The 57th and 60th motor rifle brigades provide core maneuver capacity. The T-72B main battle tank mounts a 125 mm 2A46-series gun with autoloader and fires APFSDS, HEAT, and HE-FRAG ammunition. BMP-1 infantry fighting vehicles provide tracked mobility with a 73 mm 2A28 cannon and 7.62 mm coaxial machine gun. The 2B17-1 Tornado-G is a modernized 122 mm MLRS compatible with legacy BM-21 rockets and extended-range munitions; it supports rapid, area-saturation fires. The 2S19 Msta-S is a 152 mm self-propelled howitzer with a conventional firing range around 24–29 km, greater with rocket-assisted projectiles. Tor-M2U short-range air-defense systems provide point defense for maneuver units.
Operational-Tactical Missile Capability
The 20th Guards Missile Brigade (military unit 92088) fields the 9K720 Iskander-M. Iskander-M employs the 9M723 solid-fuel quasi-ballistic missile and is associated in Russian service with the 9M728 cruise missile; official range figures for the ballistic component are up to 500 km depending on missile and payload. The system is designed for precision conventional strikes against operational-level targets such as command nodes, air-defense assets, infrastructure, and other high-value objectives.
Artillery and Fire Support
The 305th Artillery Brigade (military unit 39255) augments fires with multiple rocket, heavy mortar, and long-range gun artillery. BM-27 Uragan is a 220 mm MLRS with a typical maximum range around 35 km depending on rocket type. The 2S4 Tyulpan is a 240 mm self-propelled mortar capable of delivering heavy high-explosive and specialized munitions, with conventional ranges around 9–10 km and up to approximately 19 km with rocket-assisted projectiles. The 2S5 Giatsint-S is a 152 mm self-propelled gun with ranges commonly cited in the 28–33 km band using standard ammunition. The MT-12 Rapira is a towed 100 mm anti-tank gun used for direct-fire defense and coastal or anti-landing roles.
Ground-Based Air Defense
The 8th Anti-Aircraft Missile Brigade (military unit 36411) employs the 9K37 Buk-M1 medium-range system, typically using 9M38-series missiles with engagement ranges up to approximately 35 km under standard conditions. At the tactical level, Tor-M2U systems within the motor rifle brigades provide short-range air defense, with engagement distances generally up to 12–16 km depending on missile variant. These ground forces air-defense assets operate in coordination with regional Aerospace Forces air-defense units.
Engineer Support
The 35th Engineer-Sapper Regiment (military unit 43294) provides mobility, counter-mobility, and survivability functions including route clearance, obstacle emplacement, field fortification, construction and repair of fighting positions, bridging, and water obstacle support. When tasked, engineer units also support disaster response and humanitarian demining. Specific equipment holdings, bridge classifications, and boat assets are not publicly disclosed.
CBRN Protection
The 25th NBC Protection Regiment (military unit 58079) conducts chemical, biological, radiological, and nuclear defense tasks, including contamination reconnaissance, decontamination of personnel, equipment and terrain, aerosol smoke and camouflage operations, and operation of specialized decontamination and water purification systems. Subunit composition and equipment densities are not publicly released.
Logistics and Sustainment
The 101st Separate Logistics Brigade (military unit 11338) provides material-technical support, including supply, transportation by road and rail, field warehousing, fuel and lubricants distribution, repair and recovery support in conjunction with dedicated maintenance elements, and field services such as water and bath-laundry points. Army-level logistics enable sustained operations by moving ammunition, fuel, and spares from theater depots to brigade support areas and forward distribution points.
Storage and Repair Bases
The 245th (military unit 92910) and 247th (military unit 30615) Weapons and Equipment Storage and Repair Bases are echeloned maintenance and storage sites responsible for long-term preservation, refurbishment, controlled cannibalization, and readiness generation of ground systems. They provide surge capacity to re-equip active units and generate reserve formations when directed. Detailed inventories, exact capacities, and site layouts are not publicly available.
Infrastructure and Mobility
The formation benefits from access to the Trans-Siberian Railway and the Vladivostok port complex for strategic lift, as well as the A-370 highway network for intra-theater ground movements. Ussuriysk hosts large rail loading areas and workshops suitable for heavy equipment handling. Multiple regional training areas in Primorsky and neighboring Khabarovsk Krai support live-fire and maneuver training; comprehensive public listings of range names, sizes, and schedules are limited.
Force Protection and Support Enablers
Army-level support typically includes medical, signals, reconnaissance, electronic warfare, military police, and rear-area security elements organized under the headquarters and its brigades. These enablers protect critical nodes such as command posts, ammunition depots, fuel storage, and railheads. Specific subunit identifiers beyond those listed are not provided here.
Readiness Considerations and Data Notes
The unit identifiers and equipment types listed match commonly reported holdings for the named formations; exact equipment quantities, modernization states, and current deployments are not publicly disclosed by authoritative sources. Command assignments and equipment configurations in the Russian Ground Forces are periodically updated; therefore, commander identity and specific equipment variants should be treated as time-sensitive and verified against the latest open-source records.
