"Even in a gunfight, we'd just get our asses kicked by the simplest rifles."
Russian soldiers posted a video testing the "unparalleled" bulletproof vest "Module-Monolith," produced by JSC "Special Materials Research Institute" (St. Petersburg). During the experiment, all five bullets penetrated the armor plate completely. The soldiers expressed their dissatisfaction with the quality of the heavy and useless gear: "Just f*cking great. Thank you, Ministry of Defense."
It was shot with standard x39 (AFAIK) ... x54r is the bigger cart used in dragunov or PKM
Those cartridges sure looked like 54r to me. But I could be wrong
You are wrong, those are 5.45x39mm being fired out of an ak-74. 7.62x54r are much bigger and don’t have an associated Bakelite mag like the one used, and on top of that they aren’t fire out of AKs. The only thing close is a molot hunting rifle.
