n/a Separate Radio-Technical Regiment GRU
Identification
Open sources confirm that Kamen-na-Obi hosts military units 03025 and 28127, but they do not verify the user-supplied label of a GRU separate radio-technical regiment for this site. In January 2024, local reporting identified v/ch 28127 as an engineer-sapper battalion, while an official labor-safety registry entry and a district education report place v/ch 03025 in Kamen-na-Obi as an active military formation.

Urban garrison footprint
Registry-based records place v/ch 28127 in the city’s DOS quarter, and a 2003 Russian government order records federally owned military-town infrastructure of v/ch 15967 in Kamen-na-Obi, indicating a long-standing urban military footprint in the city. This supports the HQ placemark as part of a real Kamen-na-Obi garrison area, but it does not publicly tie the placemark to a GRU headquarters.

Verified roles
The clearest publicly documented role is for v/ch 28127: school open-day reporting tied it directly to the Engineer Troops and described it as an engineer-sapper battalion in Kamen-na-Obi since 2003, under commander Veniamin Fokin in January 2024. For v/ch 03025, verified public reporting shows a fixed garrison with a checkpoint, a memorial at the entrance, community-facing military training, and technical/support billets listed in an official 2020 labor registry entry; these sources do not publicly confirm a SIGINT or GRU mission.

Southern placemarks
For the two southern placemarks labeled command post and "Object Sosna," I found no authoritative public source in the reviewed material that names those sites or links them to v/ch 03025 or 28127. The accessible record set identifies the Kamen-na-Obi garrison by unit numbers, commanders, training events, and civic activity, not by a published "Sosna" facility designation; exact function of those coordinates therefore remains unconfirmed.

Assessment
Best-supported identification is not a verified GRU radio-technical regiment, but an ambiguous Kamen-na-Obi military cluster that publicly includes active unit numbers 03025 and 28127, with 28127 specifically documented as an engineer-sapper battalion. Older EGRUL-derived records show 03025 and 28127 as liquidated or reorganized legal entities, while later official and local sources still use both unit numbers, suggesting administrative reorganization or changed subordination rather than a clean one-to-one lineage. Confidence is therefore moderate for the city-level garrison identification, but low for the specific GRU/radio-technical attribution and low for the exact command-post/"Sosna" mapping.
