The agent conducted reconnaissance of the 28th arsenal of the Russian Aerospace Forces near the settlement of Znamianka-1 in the Tambov region.
The unit is tasked with the storage and maintenance of both operational and decommissioned space equipment.
The arsenal is a military facility of heightened secrecy, where missiles, measuring and launching equipment, and satellites are stored.
The agent collected data on the activity within the arsenal, as well as the equipment and transportation used by the staff. This enabled the establishment of more detailed information about the personnel, including their personal data.
As previously reported by Ukrinform, an agent of the "ATESH" movement discovered a concealed ammunition depot of the Russians in temporarily occupied Crimea.
