EVERYONE knows troop numbers because the Russians have been open about it and it’s been in Western news sources all over. You should check it out. It’s actually been a scandal in Russia how few troops have been deployed.
They opened up the operation with only 200k men! Hence the failure from near quick victory.
How do YOU get YOUR casualty numbers? Are you an insider? There’s a ton of Western -and Russian/Ukranian propaganda, but do you have any hard facts? The numbers deployed are fairly well known, Casualty numbers are not. Your claims make absolutely zero sense operationally and just at a common sense level.
