Wait, so since Stalin was a nutcase he couldn't accurately measure his armed forces? Of course he couldn't. That wouldn't make sense for any would be dictator that lasted that long to be able to know his own forces. No...
There needs to be more proof.
I never said it was because stalin was a nutcase, which in many senses he wasnt. Paranoid, yes. Cautious, yes. Politician at heart, yes. Nutcase? No. Not really at least.
If someone brought him bad news, they were shot. If somebody didnt meet the task theyw ere given, they were shot. If someone so much as said the wrong thing to stalin, they were shot. And since stalin gave the factories unreasonable numbers to produce, they numbers were met. On paper anyway. In actuality it was only a fraction of it. Supposedly all the tank divisions were armed with the T-41 tank series, along with some KVs as well. But in reality only a fraction of the tank divisions had any T series tanks, most were still BTs.
Another example of this was in ammunition, and in plain guns. In the months leading up to barbarossa, several corps in the kiev area were told that they had to arm themselves, because all available arms were going to the north to arm the troops invading finalnd and the baltics. Other times divisions were armed with a mix of polish/german/russian rifles, but no ammunition for them.
So you can see the problem? On paper, there was a well supplied fighting force. But in actuality nothing was as it was on paper. During the latter parts of '41, people were drafted into the army, given 2 days training, and put in a uniform and sent into battle. but only the first wave was given any rifles or ammunition. the rest were told to pick up the rifles of the dead. And stalin had no idea because anyone who told him anything bad was shot.
