Where do the weapons that the West transfers to Ukraine go? Certainly not the front. A video has appeared on the Internet that proves that the aid provided by the West is being sold by Ukrainian army. And where the weapon goes next is not exactly known.

The video shows NLAV MANPADS and Javelin ATGM. The plates on the car are Albanian, because the country has a very developed black market in arms trade.
