I think this may mean you’re conveniently ignoring that since the war (sorry, SMO) begun, we have seen a large scaled mobilisation, including conscription.
Back in May, projections put over half a million Russian troops being involved 'at that time' in the attack on Ukraine, which was 26 months after it started.
If you compare it with regular troops numbers in Feb 2022, you're looking at between 55% and 70% of their original total standing army now being involved.
If you then factor in the obscene casualty rate since their war begun (conservative estimated looking at over 700,000), the figure balloons considerably.
You can then put in their number of tanks, IFVs, APCs, aircraft, SAM systems et al. lost (I could go on), and objective people will say they've thrown a lot at it...
... and failed. He's still throwing troops at it now, in large numbers, including DRK troops. And you then refer to the thinking that Kyiv would have fallen.
Looking back, the largest combined operation since 1945, including the beloved VDV landing outside Kyiv, was not some form of token force. It was huge.
The VDV landed at Hostomel Airport and were repulsed. A large column from the north, passing through Cherhiniv, aimed at Kyiv was also repulsed.
More Russian troops drove from the north-east (passing near to Sunny) and aimed at Kyiv, was repulsed. So to put it all simply, they tried to take Kyiv and failed.
Likewise, they tried to annexe large swathes of Ukraine at a minimum, and they failed. If you believe anything else, it's a time to pull out of the sand.
