It shows how broken the command structure is for Russia; the training was probably appropriate but someone decided they needed infantry now due to the well massive amount of deaths. Of course this entire 'war' has been a cluster foobar by the Russian command structure in a major way. I mean go all the way back to Feb where the entire army stalled on their march to Kiev due to lack of appropriate planning. The entire thing was laughable. Also the massive amount of deaths they are suffering the past few months should not be occurring but the Russian command structure don't really give a hoot about Russian lives and perhaps they shouldn't given the equipment and training they are being provided but this is part of the problem and perhaps what led to the invasion in the first place - the total lack of empathy for human life.
This whole 'east vs west' story is just propaganda motivation.
Russia’s main problem from day one was no infantry. Units were all light on infantry even when equipped well, outside of maybe the elite formations.
Now, well into the war, when they’re firing maybe 20% as much artillery due to a shortage of shells, they train more artillery men? This goes back to the culture of lying to everyone about everything. Not enough transparency about what they really need, and that’s motivated infantry to support their tanks, artillery, etc. At the end of the day a man still has to go take ground and hold it to move forward.
I imagine what happened here is that they have an artillery school so someone made use of it, paying no regard to the actual needs of the army. The double tragedy for Russia is that if these guys were motivated and intelligent enough to be successful in artillery school they’d probably have made quite good infantry as well. Now instead due to corruption and stupidity you waste months of training and some of your better conscripts as cannon fodder.
