5th Combined Arms Army
Identification
This record matches the headquarters of Russia’s 5th Combined Arms Army, military unit 06426, in Ussuriysk, Primorsky Krai, within the Eastern Military District. A Russian Ministry of Defense administrative order listed v/ch 06426 at 51 Timiryazeva Street, Ussuriysk, and ISW’s 2023 Russian ground-forces ORBAT also places the 5th Combined Arms Army in Ussuriysk. Russian state reporting says the formation received the Guards honorific in April 2024, so current open sources often style it as the 5th Guards Combined Arms Army.

Geographic relevance
In a 2018 ground-forces study, ISW assessed that the Ussuriysk-based army is positioned to cover Russia’s approaches toward the Chinese and Korean borders and the Vladivostok axis. The corroborated spread of its garrisons across Ussuriysk, Sergeyevka, Spassk-Dalny, and Bikin is consistent with a regional land-force headquarters for southern Russia’s Far East rather than a single local barracks site.

Core subordinates
The clearest corroborated subordinate structure in open sources centers on the 127th Motorized Rifle Division at Sergeyevka and army-level fires units in Primorye. ISW’s 2023 ORBAT lists the 127th Division under the army, with the 57th Guards Motorized Rifle Brigade at Bikin, the 305th Artillery Brigade at Ussuriysk, and the 20th Missile Brigade at Spassk-Dalny subordinate to army HQ; the 2009 MoD order separately places the matching unit numbers 44980, 46102, 39255, and 92088 at those same garrisons.

Order-of-battle gaps
One important placemark-level ambiguity is the former 60th Separate Motor Rifle Brigade. ISW’s 2018 ORBAT still listed a 60th Separate Motor Rifle Brigade in Kamen-Rybolov within the 5th Army grouping, but ISW wrote in April 2023 that the 60th Brigade had become the 143rd Motor Rifle Regiment of the 127th Division in 2019 and that later references to the 60th Brigade may reflect legacy naming. Even so, battlefield reporting in 2024–2025 continued to describe a 60th Motorized Rifle Brigade as part of the 5th Army, so its exact current administrative designation is not fully settled in open sources.

Infrastructure and sustainment
The headquarters is the center of a dispersed Primorye military network. Beyond the Ussuriysk, Sergeyevka, Bikin, and Spassk-Dalny combat garrisons, public ORBAT data identifies army-associated storage and repair bases tied to v/ch 30615 at Monastyrishche-2, v/ch 92910 at Lesozavodsk, and a similar base at Bikin; the MoD’s 2009 order corroborates the same unit numbers and locations for 30615 and 92910. This indicates rear-area maintenance and storage depth behind the Ussuriysk headquarters. ([globalsecurity.org](https://www.globalsecurity.org/military/world/russia/5-army-orbat.htm))
Current force posture
Despite permanent basing in the Russian Far East, open reporting indicates that substantial elements of the army have been committed to the southern Ukraine theater. A 2024 TASS report said the 5th Army was holding defense on one of the hottest sectors of the Zaporizhzhia front; ISW tracked elements of the 127th Division and 305th Artillery Brigade near the Velyka Novosilka axis in 2024–2025; and on December 27, 2025, the Russian MoD/TASS named the 57th and 60th brigades plus the 114th Regiment of the 127th Division in the seizure of Huliaipole. The Ussuriysk headquarters therefore appears to remain the administrative home station for a formation whose combat elements have been repeatedly employed far from Primorsky Krai.
