Russia Ukraine war, page-199510

Now you're just talking crap, there is no way in hell any rational military advisers would have encouraged Putin to " take" Kiev with only 40k troops.
Even back then it was well discussed that a minimum of half a million troops would be required for an initial assault on Kiev plus additional troops to replace the very high casualties expected in a high attritional urban combat environment!
Not to mention the secure logistical and supply routes required, which they did not have.
Give yourself a chance and read up a little on military tactics and doctrine!
