I disagree. I think Putin has very real issues in manpower and equipment now.
Why else would he be begging for equipment and fighting men from idiots.
Why would he be blanket conscripting from captured areas and prisons... The worst kind of conscript you can have.
The reserve force he put together was smaller than expected and routed in days.
50K+ Dead so far means in excess of 250K in total that are killed/prisoner/wounded. 2 years worth of intake.
Also you cannot just replace with new intake. Leadership/officers take time to train. Modern equipment takes time to train.
To do this properly he actually has to make this a "war" and that creates
@home problems for him.
Atm Russia is the biggest arms supplier to Ukraine.....
