Performance of a military is not based on how many weapons or number of equipment they have.
When we trained to fight the old Warsaw Pact forces, we believed we faced and trained for a numerically superior force, and also supposedly competent and committed personnel. I suspect the thoughts of WW2 were still ingrained in the Russian people's psyche.
But Russia has changed. It is more corrupt, more divided. The weapons are crap, the personnel untrained, ill-disciplined and unmotivated. Money has been syphoned off to dachas and yachts of the elite, and the proletariat kept happy with controlled access to western goods and ideals whilst fed the party line.
Look at their "Spetsnaz". A name that would normally make a few hairs stand up with any opponents, and one that should have meant highly trained, highly skilled special forces. And yet every single Spetsnaz operation in Ukraine has failed - and failed against "normal" infantry. Look at their ships - they have taken to craning a lorry on the back to provide air defence! Look at their fat old fighter pilots - and their use of hand held Garmin GPS units stuck to the cockpit glass like in an old Ford Sierra.
There is no comparison between the Russian equipment, personnel or strategy and any of the leading Western/NATO militaries.
