The google result show every male is getting conscripted, that Ukraine had 900k reservist that had military training in the last 5 years. In total like 1.2 million Ukrainian fighting force vs the 170~200k Russian fighting force plus the Donbas militia.

So 900K Ukrainian reservists are added towards the fighting force, while the Russian reservists are not?

With right goal post shifting and creative definitions of "fighting force" you may be able to show that Ukrainians are a larger force.

Then there is this thing as reality. On actual battlefields Russians outnumber Ukrainians.
