Censor.NET reports referring to an investigation by InformNapalm international OSINT group.
"A long trail of clues that helped reveal several secret deliveries of Russian military equipment to the Donbas was discovered after one of our volunteers had found a short emotional comment on VK social media left by a Russian militant to the post by the Russian Ministry of Defense press service: "Got busted, motherf@ckers." This comment became the first puzzle fragment that inspired our team to start looking for connections between militants and led us to another piece of Russian military equipment in the Donbas - Zoopark-1 counter-battery radar," the publication says.
The 1st connection: between Russian mercenary from St. Petersburg Mister Evil (real last name - Golovnya) and Vladislav Buslaev.
The 2nd connection: between Vladislav Buslaev and his comrade-in-arms Vania-I Egorov.
Egorov and Buslaev took photos in the passenger railway depot in Donetsk, close to Spartak village. We circled in red the same water tower found on their photos (48.084537, 37.7884895).
Ivan Egorov has a favorite scarf. You can see it in the photos below:
"Semi-automated data collection system UKROPalantir shows that by now Egorov has already deleted some of the previously posted photos. Apparently he has realized his commanders might not appreciate that he exposed Russian-made counter-mortar radar 1L271 Aistenok which had been secretly sent to the Donbas," the investigators note.
The photo with Aistenok in the background was taken at the old gob pile site. If you take a closer look, you will see a cord reel behind Egorov and cable running from a small hideout to the radar.
More information about Aistenok counter-mortar radar
"To improve the efficiency of shelling, artillery units require special equipment that would allow adjust fire and control aiming results. Another important task is to suppress enemy artillery which also requires special military hardware. Mobile radar systems can detect artillery projectiles, locate enemy guns or ground point of impact. They are used by both self-propelled artillery and mortar detachments.
"Aistenok radar system is primarily designed to monitor fire of friendly and enemy artillery. Aistenok can track 81-120 mm mortar shells in flight. It automatically calculates trajectory and projectile parameters while determining the points of launch and landing. This information can be used to fire hostile targets with counter-battery fire and calculate corrections to adjust friendly fire.
"1L271 system can also control 122-152 mm caliber artillery shelling (photos in a related article about Zoopark-1 radar coincidentally reveal two 152 mm MSTA-B howitzers hidden in the building). In this mode the radar tracks and calculates the points of shell bursts on the ground, so that artillery can adjust fire to improve aiming.
"The third application of 1L271 radar is to detect on-the-ground moving targets of tank type. Enemy position data gathered by the radar can also be transmitted to artillery units for the strike," the article reads.
In lieu of a conclusion we will quote information published by The Military Review (Russian website):
"Since 2008, 1L271 Aistenok radar has been frequently presented at various arms and military equipment shows. However, information on acquisition of these systems by the Russian Army is not available. Curious news related to the system operation appeared several days ago. On Jan. 15, militia of the Donetsk People's Republic allowed OSCE observers to their positions. During this visit different systems were demonstrated to the observers, including Aistenok, which is used by militia to detect the shellfire coming from the Ukrainian Armed Forces. Thus, the present conflict can be regarded as the first war in which this new Russian radar system is used.
"The details about 1L271 radar supply to the DPR are unknown. Plans of the Russian Ministry of Defense with regard to the purchase of these systems for own military units also remain secret. It is entirely possible that the new radar system of reconnaissance and control first should be test-run in real war conditions during the current conflict, and [only] after that they will be purchased for Russia's Armed Forces."
