11th Army Corps
Identification
This record corresponds to Russia’s 11th Army Corps in Kaliningrad Oblast, a ground formation created in 2016 for the Baltic Fleet’s coastal and land component. Public open sources conflict on the exact HQ site: a 2024 DIIS map places corps HQ functions in Kaliningrad city, while other open reporting and a 2020 command ceremony place the corps command in Gusev; the reviewed sources therefore do not support a single unambiguous HQ point.

Command
Admiral Aleksandr Nosatov introduced Andrey Ruzinsky as the new corps commander on 7 August 2020 in Gusev. Russian reporting in April 2024 still described Ruzinsky as commanding the corps, but the reviewed sources did not provide a newer official confirmation as of March 12, 2026.

Disposition
Reviewed open sources place key corps elements at the same main nodes reflected in this record: the 152nd Guards Missile Brigade at Chernyakhovsk; and, in Kaliningrad, the 7th Motor Rifle Regiment, 22nd Air Defence Regiment, and 244th Artillery Brigade. DIIS also maps major armored elements in Gusev, including the 11th Tank Regiment, showing the corps is dispersed across Kaliningrad city, Gusev/Sovetsk, and Chernyakhovsk rather than concentrated at one site.

Force build-up
Russian reporting in late 2020 and 2021 said a motor-rifle division was being formed inside the corps in Kaliningrad Oblast; by March 2021 the revived 18th Guards Motor Rifle Division had received its historical banner from the deputy defense minister via the corps commander. This indicates a post-2016 expansion from a corps centered on separate regiments and brigades toward a heavier divisional structure in the exclave. ([tass.com](https://tass.com/defense/1232041))
Operational use
Units from Kaliningrad Oblast, including the 11th Army Corps, were deployed into Ukraine from the beginning of the 2022 invasion and fought around Kharkiv, where DIIS says the corps suffered considerable losses. Ukraine’s General Staff later claimed the corps lost over 50% of its personnel and more than 200 vehicles during the Kharkiv retreat; that specific number should be treated as a Ukrainian wartime claim, not independently confirmed in the reviewed sources.

District and geography
Russia’s Western Military District was formally dissolved on June 5, 2024, and subsequent Russian reporting placed the Kaliningrad-based 11th Army Corps in the restored Leningrad Military District. The corps’ main nodes—Kaliningrad, Chernyakhovsk, Gusev, and Sovetsk—sit across the exclave’s urban and logistics belt and near Lithuania-facing crossings, underscoring its role in defending and sustaining the enclave rather than operating as a single-point installation.
