As reported by Censor.NET citing InformNapalm, the photos were posted by Konstantin "Vandumin" Goncharenko, a Russian citizen from Buryatia and former employee of the private security company Kodeks. Here are his profile and photo album. The photos indicate a recent reinforcement of this military unit with new equipment. Please note the good condition of the mounted devices, armor and paint of the BMP-2's and BTR-80 in the picture below.
The warehouse where the picture was taken previously appeared in investigation Potemkin Revealed a Location of the Russian Invaders' Base in Makiivka. It was a factory for precast concrete products in the city of Makiivka in Donetsk region.
Goncharenko's photo of the Russian modernized BTR-80 turned out very good. The BTR-80 is upgraded with a Pl-1 laser illuminator and a TKN-4GA-01 optical sight produced by the Rostov Optical Mechanical Plant. The authors of the investigation specify that this modification has not been exported to Ukraine and, therefore, could not have been captured from the Ukrainian Armed Forces.
Recently killed in a bomb blast (presumably by the FSB) Arsen Pavlov (aka Motorola), a Russian citizen and commander of the Sparta criminal gang, was seen in a Russian modernized BTR-80 during a military parade in the so-called DPR.
A similar BTR-80 with a new sight was demonstrated at The Presence, an exhibition of weapons captured by the Ukrainian Armed Forces in the Donbas.
More on the subject of this investigation is available in the Database and Video Overview of the Russian Weaponry in the Donbas that presents over 30 types of Russian weapons and military equipment used in the Donbas.
