12th Anti-Aircraft Missile Regiment
Identity
Best-fit identification is the Russian 12th Anti-Aircraft Missile Regiment, military unit 85702, based in Sevastopol. Ukrinform, citing the ATESH partisan network, identified unit 85702 as the 12th regiment in Sevastopol, and RFE/RL’s Crimea desk described the 12th regiment as one of the 31st Air Defense Division’s core elements headquartered in Sevastopol.

Mission
Open reporting places this regiment in the western-Crimea air-defense role. RFE/RL reported that its two S-400 battalions are positioned at Cape Fiolent/Sevastopol and near Yevpatoria, with the stated mission of covering the main Black Sea Fleet base in Sevastopol and nearby airfields including Belbek, Kacha, and Novofedorivka; TASS separately reported the Sevastopol regiment’s re-equipment from S-300PM to S-400 under the 4th Air and Air Defense Army.

Sevastopol site
The strongest coordinate match in the supplied record is the Sevastopol/Fiolent-area placemark near 44.544N, 33.433E. Ukrinform reported regiment equipment at 44.547158, 33.435834 in December 2025, and TASS had earlier reported additional S-400 battalions assuming duty in the Cape Fiolent area of Sevastopol; that makes the Fiolent-axis site a high-confidence match to one operational element of this regiment. The exact supplied HQ point near 44.581N, 33.575E was not publicly confirmed in the reviewed sources.

Yevpatoria element
The supplied western-Crimea placemark near 45.219N, 33.261E is consistent with the regiment’s documented Yevpatoria-area battalion, but I did not find a public source confirming that exact coordinate. TASS reported a third S-400 battalion entered duty in Yevpatoria in September 2018, and RFE/RL later described the 12th regiment’s second S-400 battalion as being in the Yevpatoria area. BBC also reported that Ukraine said it struck a Russian S-400 facility near Yevpatoria on 14 September 2023, underscoring the site’s operational relevance and exposure.

Garrison status
Public Russian litigation records indicate unit 85702 was functioning as a standing garrison with contracted support services in 2021-22; a Moscow arbitration case referenced food-service inspections at unit 85702 and cited a 10 October 2021 letter from the acting commander of the unit. Separate December 2025 reporting observed Russian vehicles and personnel at the Sevastopol regiment area, supporting continued active use of the site network.

Confidence gaps
One supplied placemark appears doubtful for this regiment: the point near 45.688N, 34.407E lies in the Dzhankoi area. TASS reported an S-400 battalion went on duty near Dzhankoi in November 2018, but RFE/RL later linked that Dzhankoi air-defense element only to the 31st Air Defense Division broadly and, on an unofficial basis, to the 18th Guards Anti-Aircraft Missile Regiment rather than the 12th; this Dzhankoi placemark should therefore be treated as unverified for unit 85702.
