So, can you give me some pointers to the explanation how they wouldn’t be worse trained? Especially given the previous attempt, the (already failed) “third army”? As for “new stuff” - the actually new stuff didn’t exist or was so scarce it didn’t matter. Here I mean the “new stuff” from Russian army point of view. This includes late Cold War. Note how Russia can’t manufacture Armata tanks or BMP3, so it’s switching back to manufacturing 80’s models instead.
