The photo on the left demonstrates a Russian 7.62-mm Pecheneg machine gun, developed of a PK machine gun, in service with the Russian army. It has never been supplied to Ukraine and has never been in service with the Ukrainian army.
The photo on the right shows a large-caliber Kord machine gun with a 12.7x108-mm belted feed.
Kord machine gun was designed in the 90s to replace the NSV machine gun, the production of which partially ended up outside of Russia after the breakup of the Soviet Union. It was developed at Degtyarev plant in Kovrov city.
Nowadays, the machine gun is produced on commercial basis and has been officially put in service with the Russian Armed Forces since 1998. It was actively used by the Russian Army during the Second Chechen War and the armed conflict with Georgia in 2008.
The fact of placing this double proof of Russian weapon supplies and direct participation of Russian troops in the war in the Donbas in one post in the popular among terrorists and separatists group in a social network is a flagrant slap in the face of Russian Minister of Foreign Affairs Sergey Lavrov and all that propagandistic herd that claims that Russia is not a party to the conflict.
Only mixed anti-aircraft batteries, BM-30 Smerch batteries, Tochka complexes, and other "subscribers" of the General Staff of the Armed Forces of RF can use this headquarter vehicle.
"Terrorists, who by making selfies and taking photos of each other demonstrate exceptionally Russian models of military equipment, do it not because of foolishness, but consciously, aiming to involve Russian leaders into full-scale and open war with Ukraine, for they no longer rely on themselves even with support of Russian weapons and separate Special Forces of the RF Armed Forces. Of course, they risk being "eliminated" by Russian Special Forces for this amateurishness, which goes against the official Kremlin excuses, but the choice is not so big. This is the way how Novorossya is betraying Russia in front of the world community, reducing to zero all attempts to camouflage as a hybrid army," the article reads.
