1st Army Corps
Organizational Overview (1st Donetsk Army Corps)
The 1st Donetsk Army Corps is a corps-level formation aligned with the Russian Ground Forces and composed largely of units originating from the former armed formations of the self-proclaimed Donetsk People’s Republic. By late 2022, Russian official communications began referring publicly to the “1st Donetsk Army Corps,” indicating its incorporation into Russia’s formal command structure. Open-source defense assessments consistently place this corps under the 8th Combined Arms Army of the Southern Military District. Its primary area of operations is the Donetsk axis in eastern Ukraine.
Headquarters and Command Location
Headquarters: Donetsk, Ukraine (city under Russian occupation). The administrative military unit number v/ch 00100 is widely reported in open sources as the headquarters identifier for the 1st Army Corps in Donetsk. The Russian Ministry of Defence does not publish a comprehensive, official registry of unit numbers and addresses; therefore, while v/ch 00100 is frequently cited in public documents and reporting, an exact street address is not officially confirmed in publicly available sources.
Administrative Identifiers (v/ch) and Verification Status
The military unit numbers provided—v/ch 00100 (corps HQ), v/ch 08801, and v/ch 08826—match numbering patterns repeatedly observed for Donetsk-origin formations. Such identifiers have appeared in open-source materials including recruitment notices, legal filings, and veterans’ documentation. However, Russian MoD does not maintain a publicly accessible, authoritative list of all v/ch assignments. As a result, unit-to-number mappings should be considered as open-source attributions rather than formally confirmed by the MoD.
1st Separate Motor Rifle Brigade (v/ch 08801) — Overview
Designation: 1st Separate Motor Rifle Brigade (often referred to in earlier local publications as the “Slavyanskaya”/Slavyansk Brigade). Reported v/ch: 08801. Basing: Donetsk urban area (exact barracks and depot locations are not officially published and have varied due to operational deployments). Role: Combined-arms motor rifle formation directly subordinated to the corps, configured for offensive and defensive operations in dense urban and fortified terrain typical of the Donetsk front.
1st Separate Motor Rifle Brigade — Equipment Profile
Reported equipment associated with this brigade includes T-72B main battle tanks, T-64BV tanks, BMP-1 infantry fighting vehicles, and 2S1 Gvozdika 122 mm self-propelled howitzers. The presence of T-64BV reflects the sustained use of legacy and captured platforms in Donbas since 2014, alongside the more standard Russian T-72B series. Equipment holdings in active warzones are fluid; the types listed are documented across multiple years but may rotate or change in quantity over time.
110th Separate Motor Rifle Brigade (reported) — Status and Attribution
Designation reported: 110th Separate Motor Rifle Brigade. Reported v/ch in some open sources: 08826. Important caveat: Multiple independent open-source compilations have historically associated v/ch 08826 with the 100th Separate Motor Rifle Brigade (often known as the “Republican Guard”), not the 110th. Official Russian MoD publications do not provide a definitive, publicly accessible mapping. Therefore, the linkage of v/ch 08826 to the 110th Brigade should be treated as unconfirmed. Additionally, the designation “110th” is frequently confused with Ukraine’s 110th Separate Mechanized Brigade, which is a different formation on the opposing side.
110th Separate Motor Rifle Brigade — Reported Equipment
Open-source reporting that attributes a 110th Separate Motor Rifle Brigade within the 1st Army Corps commonly lists T-72B and T-64BV tanks, BMP-1 and BMP-2 infantry fighting vehicles, and BM-21 Grad 122 mm multiple rocket launchers. As with other formations in this theater, equipment sets are a mixture of Soviet-legacy and Russian-standard platforms. Given the attribution uncertainties noted above, these holdings should be considered reported rather than officially confirmed for this specific brigade.
Equipment Technical Notes — Tanks
T-72B: Soviet-origin main battle tank (mid-1980s introduction) with 125 mm 2A46-series smoothbore gun, typically fitted with Kontakt-1 explosive reactive armor on earlier variants and powered by an ~840 hp V-84 series diesel. T-64BV: 125 mm 2A46-2 gun, Kontakt-1 ERA, and a 700 hp 5TDF engine. While both fire 125 mm separate-loading ammunition, T-64 family sustainment differs from T-72 series (engine, transmission, and some systems logistics), imposing additional maintenance and spares requirements when both types are fielded in the same formation.
Equipment Technical Notes — Infantry Fighting Vehicles
BMP-1: Amphibious IFV with a 73 mm 2A28 Grom gun and 7.62 mm coaxial machine gun, typically fitted with the 9M14 Malyutka ATGM in baseline configurations; effective primarily for infantry transport under fire and limited direct support. BMP-2: Upgraded IFV with a 30 mm 2A42 autocannon, 7.62 mm coaxial machine gun, and 9M113 Konkurs ATGM capability; improved anti-personnel and light-armor lethality over the BMP-1 while retaining amphibious capability under permissive conditions.
Equipment Technical Notes — Artillery and Rockets
2S1 Gvozdika: 122 mm self-propelled howitzer with a standard HE range of approximately 15.3 km, extendable to roughly 21.9 km with rocket-assisted projectiles, providing mobile, tracked indirect fire support. BM-21 Grad: 122 mm 40-tube multiple rocket launcher with typical range of ~20.4 km using standard 9M22-series rockets and up to ~40 km with extended-range munitions (e.g., 9M521 family), suitable for area suppression and counterbattery missions when cued by reconnaissance.
Logistics and Lines of Communication
Sustainment into the Donetsk area has historically relied on cross-border corridors from Russia’s Rostov Oblast. Key ground routes include approaches via Novoazovsk and the Uspenka border crossing, with onward movement to Donetsk. Rail nodes such as Ilovaisk and Debaltseve have long served as principal junctions supporting military rail logistics in the region. Mixed tank fleets (T-72B and T-64BV) complicate maintenance and spares provisioning, while standardized 122 mm artillery and rocket munitions simplify certain supply lines.
Infrastructure and Support Facilities in Donetsk
The corps and its brigades make use of dispersed facilities within and around Donetsk, including vehicle parks, maintenance workshops, ammunition and fuel storage areas, and temporary forward operating sites. Given the persistent threat of long-range strikes, storage and staging areas are frequently relocated or camouflaged, and heavy equipment is often dispersed among industrial zones and urban cover rather than concentrated in large, exposed garrisons. Exact facility locations and capacities are not publicly disclosed.
Operational Employment on the Donetsk Axis
The 1st Donetsk Army Corps and its subordinate brigades conduct offensive and defensive operations along the Donetsk front, including urban and fortified localities where combined infantry-armor teams, indirect fire, and engineer support are critical. Public Russian MoD briefings since late 2022 regularly reference the actions of “units of the 1st Donetsk Army Corps,” indicating sustained engagement along this axis. Detailed, current dispositions, task organization, and rotation schedules are not publicly available.
Legal and International Status
Internationally, Donetsk is recognized as part of Ukraine. The Russian Federation declared the annexation of Donetsk Oblast on 30 September 2022, a claim not recognized by Ukraine and the majority of UN member states. The presence and basing of the 1st Donetsk Army Corps within Donetsk therefore occur in territory internationally recognized as occupied. This status affects external assessments and reporting but does not change the on-the-ground military command relationships described above.
Uncertainties, Gaps, and Confidence Assessment
Confirmed: The existence of the 1st Donetsk Army Corps, its headquarters in Donetsk, and its operational role on the Donetsk axis; public Russian MoD usage of the corps designation; long-standing use of mixed Soviet/Russian equipment in Donbas; and reliance on the logistical corridors noted. Reported but not officially confirmed: Precise v/ch-to-unit mapping for specific brigades, including the attribution of v/ch 08826; detailed basing locations for v/ch 08801 and the alleged 110th Brigade; current, exact equipment quantities and subunit-level order of battle. Due to the absence of an official, public MoD registry and the fluidity of active combat formations, brigade identifiers and holdings should be treated with caution. Overall confidence in the high-level organizational picture is moderate to high; confidence in specific v/ch-to-brigade mappings beyond the corps HQ is moderate to low without additional corroboration.
