I agree with all that you said, however, I believe they have lost more men & women on the battle field than has Russia. Whether we find out exact numbers is probably no going to be revealed. So, that is just my personal option based upon reports I have heard.
It’s possible.
At the time of the leak, the Ukraine still enjoyed an advantage, and of all the numbers floating out there, those are about the only ones I would trust.
But yes, since then the margin has likely narrowed:
1) Russia being somewhat disorganized in the beginning has pulled their head from their ass, or so it appears.
2) Russia has adopted some of their tactics and modified as well as added new equipment to counter the threat of some of systems we have provided. For example, Excalibur (GPS guided) artillery is no longer as effective, some of our drones are less effective against their armor, many of the drones are simply being destroyed...
3) The Ukrainians had a flop of a counter offensive in 2023 which was very costly to them.
I am fairly sure that Ukraine’s 2023 pre-counter offensive advantage of 1.52-1.7:1 margin in casualties is less today.
Even so, Russia enjoys a 3.5:1 population and military aged males advantage and what that means is obvious in a war of attrition. This is also corroborated by how Russia is mobilizing (reserves, prior service, offering contracts with bonuses) vs. Ukraine’s TCC that is doing snatch and grab operations in broad daylight to find men, wrestling them into vans to haul off.
