So now that we've had a few more hours to digest the conflict.
It appears the Russians hoped for a quick rapid seizure of major facilities and urban centers predominantly with light elite troops like VDV (Russian paratroopers). They coincided this with a surge of ballistic missile and cruise missile strikes intended to soften up Ukrainian forces and destroy the Ukrainian air force and air defense network. The Russians then launched offensives from Belarus, Russia, and Crimea, with two pincers from Belarus on each side of the Dnieper. This is a logistically demanding but strategically sensible plan since it attacks in multiple regions and prevents the Ukrainians from shifting reserves. It also makes sense since the Russians seem intent on treating this more like a police action than a serious war.
However the plan appears to have run into snags. Aggressive airborne and heliborne insertions do not appear to have been overly successful. More alarming was the failure of the Russians to destroy the Ukrainian air force and air defense network. Initially it appears the Russians were confident enough to launch a day time heliborne insertion, but subsequent Ukrainian actions have revealed their air defenses and air force remain in operation. This allegedly prevented the Russians from flying in reinforcements onboard transport aircraft as they seemed to have intended.
The Russians in response have introduced their second echelon forces along with heavier weapons to break Ukrainian defenses. This is currently ongoing and the Russians seem geared up for an assault on Kiev from multiple sides.
Despite some difficulties the Russians have still scored some noticeable success; they have pinned down much of the Ukrainian army east of the Dnieper and are preventing Kiev from redeploying its reserves. Despite efforts to do so, the Ukrainians have also failed to stop the Russian break out from Crimea. The Russians, despite some logistical difficulties, still have plenty of forces to throw at Ukraine. Unless the Russians suffer from truly catastrophic defeat, it seems likely they will be able to force Kiev to accept terms favorable to Moscow.
However the strategic situation on the other hand has turned against Russia. NATO has very openly announced its intentions to arm the Ukrainians, and European response to the invasion has been wholly negative, resulting in sanctions targeting the Russian financial means to run their state. Russia appears to have wanted a relatively light and quick war; the Russian Ministry of Defense has said virtually nothing of the conflict and Moscow has barely acknowledged a war is on. But the longer the war is fought and the more damage is done, the more the Russians will have to repair if they intend to occupy. If western Europe is freezing Russian financial assets, that will sting.
It's hard to see this turning out well for Russia in the long run. The country has effectively united European action against Moscow, while Putin's actions have ironically done more than just about anyone to cement a strong Ukrainian national identity that will likely remain averse to Russia for a long time. Various commentators, including the former American ambassador to Russia, have pointed out Putin's behavior and statements over this conflict have come across as markedly different than his usual demeanor. There may be some other issue at play here that we simply don't know about.
