1534th Anti-Aircraft Missile Regiment
Identified site
Military unit 25512 is identified in open defense reporting as the 1534th Anti-Aircraft Missile Regiment in the Angarsk, Irkutsk Oblast area. An official 2024 Irkutsk regional order lists v/ch 25512 at "g. Angarsk, kv-l 225-y, v/g 1A," which is the strongest publicly confirmed fixed address I located for this regiment.

Current footprint
Open sources indicate a dispersed footprint inside the Angarsk municipal area rather than a single isolated point. Irkutsk State University reported a 2022 field camp on the territory of v/ch 25512 in Angarsk, while Angarsk municipal materials also associate v/ch 25512 with the Meget district, suggesting additional residential or support property beyond the main Angarsk military town.

Air-defense equipment
Open defense reporting before the 2021 rearmament cycle described the regiment at Angarsk with S-300PM systems, usually as two battalions; one 2015 snapshot listed three battalions, indicating later downsizing or reorganization. In July 2021, Izvestia reported that the Russian MoD had said the regiment would complete re-equipment to S-300PM-2 by the end of 2021, but I did not locate later public confirmation that this conversion was completed at this specific regiment. ([cacds.org.ua](https://cacds.org.ua/wp-content/uploads/2019/12/%D0%92%D0%98%D0%9A%D0%9B%D0%98%D0%9A%D0%98-%D1%96-%D0%A0%D0%98%D0%97%D0%98%D0%9A%D0%98-%D0%91%D0%B5%D0%B7%D0%BF%D0%B5%D0%BA%D0%BE%D0%B2%D0%B8%D0%B9-%D0%BE%D0%B3%D0%BB%D1%8F%D0%B4-%D0%A6%D0%94%D0%90%D0%9A%D0%A0-%E2%84%96-20-131.pdf?utm_source=openai))
Operational role
Izvestia's 2021 reporting on rearmament of the 41st Air Defense Division states that the division sits within the 14th Air and Air Defense Army and covers East Siberia; the same reporting places one of the division's regiments in Angarsk. It also says the modernization effort was intended to improve protection of major hydroelectric, industrial, and resource sites in Siberia, which is consistent with an Angarsk-Irkutsk deployment.

Confidence gaps
Not every v/ch 25512-linked location in open sources appears to be a current regimental combat site. A 2005 cadastral record tied unit 25512 to several parcels in Irkutsk District, including near Ust-Baley, and later local reporting described the former Ust-Baley garrison as already gone; accordingly, the second placemark may represent an outlying air-defense position or a legacy unit-associated site, but its present role is not publicly confirmed.
