Open sources identify military unit 03216 as the 1488th Anti-Aircraft Missile Regiment at Zelenogorsk, Saint Petersburg. A Kurortny District administrative order reproduced in local official media places v/ch 03216 at Krasavitsa, 3, with the garrison polling site in the 7 km military town near Zelenogorsk; GlobalSecurity separately lists v/ch 03216 as the 1488th Red Banner Anti-Aircraft Missile Regiment in Zelenogorsk. This is a strong match to the supplied coordinates and placemark naming. ([terijoki.spb.ru](https://terijoki.spb.ru/books/posad2012_3-4_487-488.pdf))
In CNA’s June 2021 order-of-battle assessment, the regiment was part of the 2nd Air Defense Division of the 6th Air and Air Defense Army. CNA states that this division guards Saint Petersburg and neighboring areas against mass air attack, making the Zelenogorsk/Krasavitsa site part of the core long-range SAM belt protecting the city and its northwestern approaches.

As of CNA’s June 2021 assessment, the 1488th regiment fielded four battalions: two S-300PS(?) and two S-400. Russian state media in July 2025 said the regiment had previously operated four S-300PS battalions and had received multiple S-400 Triumph systems. Taken together, the reviewed sources support a dispersed multi-battalion SAM footprint around the Zelenogorsk garrison, but they do not publicly and authoritatively assign each individual firing position in the metadata to a named battalion.

Russian state and municipal sources trace the regiment to the 83rd SAM Brigade formed at Zelenogorsk-4 in 1958. The unit inherited Red Banner lineage in 1967, began re-equipping to S-300PS in 1987, and was reorganized as the 1488th regiment in 1994. A 2014 municipal article described the regiment as having been tied to Zelenogorsk for more than 50 years, reinforcing continuity of the Krasavitsa garrison.

On 21 July 2025, President Putin awarded the regiment the honorific Guards for mass heroism, according to TASS’s report on the published decrees. That award is the clearest public indicator that personnel from this Zelenogorsk-based regiment saw combat service outside their home air-defense mission; however, the reviewed open sources do not publicly confirm which subunits remained on the Saint Petersburg air-defense line versus deployed elsewhere.
