The 2nd Separate Motor Rifle Brigade, military unit 73438, is a motor rifle formation long associated with the 2nd Army Corps that originated under the Luhansk People's Republic. Its headquarters is located in Luhansk city, territory internationally recognized as part of Ukraine and under Russian control since 2014. The brigade is structured to conduct combined-arms operations at brigade level, integrating mechanized infantry, tanks, artillery, air defense, reconnaissance, and support elements. Open-source references linking military unit 73438 to the 2nd Separate Motor Rifle Brigade in Luhansk have been published consistently since 2015 and persist in reporting through at least 2024.
Prior to late 2022 the brigade operated within the People's Militia of the self-proclaimed Luhansk People's Republic as part of the 2nd Army Corps. Following Russia's announced annexation of occupied areas of Luhansk Oblast on 30 September 2022, the Russian Ministry of Defence stated during late 2022 and early 2023 that the 1st and 2nd Army Corps were incorporated into the Russian Ground Forces. The 2nd Army Corps, and by extension this brigade, has been placed under the 8th Guards Combined Arms Army of the Southern Military District, headquartered in Novocherkassk, Rostov Oblast. Integration entailed alignment to Russian Ground Forces manning, administration, and supply systems.
Headquarters and principal garrison facilities are in Luhansk city. During active hostilities the formation operates from dispersed positions across occupied areas of Luhansk Oblast, establishing field command posts, vehicle parks, ammunition storage areas, and artillery firing positions at varying distances from the front. Exact street addresses and precise coordinates of all facilities are not publicly disclosed by authoritative sources, but imagery and local reporting consistently place the unit’s administrative and support footprint within Luhansk and its immediate environs. Logistics nodes connect the garrison to supply routes from Russia's Rostov Oblast.
While current detailed tables of organization are not publicly released, open-source reporting from 2015 to 2023 describes a configuration typical of motor rifle formations in this theater: three motor rifle battalions, one tank battalion, an artillery group with self-propelled howitzers and a rocket artillery battalion, an anti-tank element, an air defense battalion or battery, reconnaissance, engineer, signals and electronic warfare elements, and medical, maintenance, and logistics units. Wartime adjustments have included ad hoc assault detachments and the incorporation of mobilized subunits. Exact subunit numbering and manning levels are not confirmed in official publications.
Photographic and video evidence over multiple years shows this brigade and other 2nd Army Corps units employing T-64 and T-72 series tanks; BMP-1 and BMP-2 infantry fighting vehicles; BTR-80 and BTR-82A armored personnel carriers; 2S1 Gvozdika 122 mm and 2S3 Akatsiya 152 mm self-propelled howitzers; D-30 122 mm towed howitzers; BM-21 Grad 122 mm multiple launch rocket systems; 120 mm mortars; anti-tank guided missiles such as Konkurs and Fagot; and short-range air defense systems including Strela-10 and ZU-23-2. The precise mix within military unit 73438 varies with losses, replenishment, and integration into Russian supply channels after 2022.
The brigade has been engaged in the Donbas conflict since 2014 as part of the armed formations composing the 2nd Army Corps, and since February 2022 it has participated in Russia’s expanded war against Ukraine. Public reporting and battlefield media place 2nd Army Corps forces, with this brigade among its constituent formations, in operations along the Luhansk front, notably during the fighting for Severodonetsk and Lysychansk in May to July 2022 and in subsequent engagements on the Svatove to Kreminna axis through 2023. Because of task organization and limited official disclosure, attributing specific engagements exclusively to this brigade is often not possible from open sources.
Precise end strength for military unit 73438 is not publicly disclosed. Motor rifle brigades in this theater typically field several thousand personnel, with numbers fluctuating due to mobilization, casualties, and reinforcement. From 2022 onward, integration into the Russian Ground Forces brought standardized contracts and access to Russian training infrastructure; training and reconstitution for 2nd Army Corps units have been reported at facilities in occupied Luhansk Oblast and within Russia’s Southern Military District. The brigade cadre comprises a mix of pre-2022 militia veterans and post-2022 contract and mobilized soldiers under Russian command.
As a brigade-level formation, the unit maintains administrative headquarters functions, barracks, vehicle parks, maintenance workshops, ammunition and fuel storage sites, medical stations, and communications hubs in and around Luhansk. Field infrastructure includes forward logistics points, repair and recovery facilities, and protected artillery positions. Sustainment is enabled by road and rail links connecting Luhansk to Russia through border crossings in Luhansk Oblast, supporting the delivery of ammunition, fuel, spare parts, and replacement equipment.
Since 2014, principal logistical axes for forces in Luhansk Oblast have run from Russia’s Rostov Oblast into Luhansk via crossing points such as Izvaryne and Dolzhanske, onward to Luhansk city and forward distribution hubs. Railheads in Rostov Oblast, including Kamensk-Shakhtinsky and Millerovo, support heavy freight movement close to the border. After formal incorporation into the Russian Ground Forces, the brigade’s supply has been integrated into Russian military logistics with Southern Military District depots providing munitions, vehicles, and materiel. These routes remain subject to interdiction risk from Ukrainian long-range fires and unmanned systems.
Luhansk city and the wider oblast are internationally recognized as part of Ukraine. Russia has exercised de facto control over Luhansk city since 2014 and announced annexation of occupied areas on 30 September 2022, a move not recognized by the United Nations. Multiple jurisdictions, including the European Union, United States, and United Kingdom, have imposed sanctions on the structures of the self-proclaimed Luhansk People's Republic and individuals linked to its armed formations. The brigade now operates under Russian command as part of the 2nd Army Corps within this legal context.
Open sources commonly refer to the formation as the 2nd Separate Motor Rifle Brigade and associate it with military unit number 73438 and the city of Luhansk. Russian-language abbreviations used include 2 omsbr. Tactical markings and callsigns are routinely altered for operational security and therefore are not reliable long-term identifiers. Russian Ministry of Defence public releases infrequently use legacy Luhansk People's Republic designations, complicating unambiguous attribution in official narratives.
During 2023 the Russian Ministry of Defence implemented Russian-style numbering and nomenclature for formations within the 1st and 2nd Army Corps. Open-source reporting frequently lists a 123rd Motor Rifle Brigade within the 2nd Army Corps operating from the Luhansk area and presents it as a successor to pre-2022 Luhansk formations. However, a publicly accessible Russian decree or order explicitly mapping the former 2nd Separate Motor Rifle Brigade military unit 73438 to a specific new brigade designation has not been released. Accordingly, the precise current official designation of the unit that previously used the 73438 identifier cannot be confirmed from authoritative public documents.
Key details such as current end strength, exact subunit structure, present equipment tables, precise garrison addresses, and names of current commanders are not published in authoritative open sources. Attributions of specific combat actions to this brigade are constrained by the practice of task organizing battalion tactical groups and limited official unit-level reporting. Statements in this report regarding structure and equipment reflect patterns documented across 2nd Army Corps units and visual evidence and are assessed with moderate confidence. Statements regarding incorporation of the 2nd Army Corps into the Russian Ground Forces under the 8th Guards Combined Arms Army are supported by public Russian Ministry of Defence communications and are assessed with high confidence.
