185th Anti-Aircraft Missile Regiment
Identification
Reviewed open sources support identifying this record with the 185th anti-aircraft/zenit missile regiment in Berezovsky, Sverdlovsk Oblast. The corroborated military-unit number in public records is 92851, not 92581: a public registry entry lists "Войсковая часть 92851" in Berezovsky, and an official Sverdlovsk regional act references utility infrastructure serving "г. Березовский, в/ч 92851, в/г 10." ([companies.rbc.ru](https://companies.rbc.ru/id/1046600160111-vojskovaya-chast-92851/?utm_source=openai))
Command
In the publicly available 2020 IISS deployment table, the 185th SAM Regiment is listed under the 76th Air Defence Division of the Central Military District's 14th Air and Air Defence Forces Army, equipped with S-400. TASS separately reported in September and December 2020 that the Sverdlovsk-oblast regiment received S-400 systems, completed initial firing preparation, and then assumed combat duty in its Ural air-defence zone.

Garrison footprint
The Berezovsky site appears to be a permanent garrison/support area, not just a transient launcher field. The official regional energy document references distribution lines serving "в/ч 92851, в/г 10," and the Sverdlovsk regional waste-management scheme lists a Berezovsky military town for v/ch 92851 with four waste-generation sources, consistent with a standing cantonment and support infrastructure.

Secondary site
The eastern placemark at approximately 56.8811N, 60.9831E matches exactly one of the former S-300PS battalion coordinates published for the predecessor 57th SAM Brigade / later 185th regiment. This makes it a credible legacy missile firing position associated with the regiment; however, the reviewed open sources do not publicly confirm that this exact site remained active after the regiment's 2020 re-equipment with S-400 systems.

Historical relevance
Historical open-source orders of battle trace the unit back to the 57th Anti-Aircraft Missile Brigade formed in the Sverdlovsk-Berezovskiy area in 1960; they record conversion to S-300PS beginning in 1986 and redesignation as the 185th regiment in 1997. TASS coverage of the regiment's 2017 centenary in the Berezovsky garrison stated that the regiment's crews were credited with the 1 May 1960 U-2 shootdown over the Urals, and a separate TASS historical review of the Powers incident places the decisive engagement in the zone of the 57th brigade near Sverdlovsk.
