I don't know if you know this about me, but my graduate school background was in the defense arena. I spent countless hours and long nights thinking about what could happen if war were to break out between large powers, i.e. Russia, the United States, China, etc. And my analysis was based on information we currently had, in that these powers would conduct pretty swift campaigns.
Boy, was I wrong, as the current war in Ukraine has proved so perfectly.
Despite the bluster of the great bear that is Russia, forces there have been stymied, broken, hunted down, and largely thrown into a meat slaughter they're ill-equipped to fight against. They're mostly untrained, have lackluster supplies and support, and are often just sent directly into the path of a firing squad like it's WWI at the advent of the machine gun.
