I was wondering one thing. Even if magically, all western companies start to send all materias to Russia, how can Russia use these tecnologies at best, considering they sent almost all skilled men to the front? Also assembly all tanks, apcs, ecc, how can they manned them, if they are short of (good) soldiers? I don't think giving a t-90m to 3 soldiers that barely knows how to start it, can make huge difference.
I'm just curios, I'm not an expert
