Honestly I think they thought Ukraine wouldn't get the help they had so most of their idea of fighting NATO would be after a Baltic or Ukraine invasion in defense mode. Either that or giving a favorite proxy like Iran the weapons to hurt us if that got hot. They know NATO was never going to invade Russia proper.
You are right, their logistics sucks and part of this I think is they never thought through a scenario where they would have to maintain long supply lines in enemy territory under attack.
The missiles and AA stuff is probably well maintained. Missiles just would need things like tests and gasket replacement after time since they only get used once. Mobile anti-aircraft is typical vehicle type maintenance. It was all probably good back in February but I bet their spares are running real low now, especially electronics components. To be honest, the AA stuff hasn't been used by Russia since Ukraine can't and won't send hostile aircraft into Russia airspace.
Their ground stuff was obviously poorly maintained and bad logistics/sanctions sealed the deal. If I had to guess, somebody was stealing the maintenance budget money and selling parts on the black market for cash. I bet half their supply depots had HUGE inventory shortfalls when they finally checked once this shyt popped off.
100% they thought they would roll on Ukraine and it would be fast enough that the world wouldn't have time to react.
I'm not military strategist, and as a result some folks on here; mostly the pro-Russian contingent; think we shouldn't speak on this war. We're potentially on the precipice of WW3...so I'm following and I'm going to speak on it.
What I've read and watched, because Russia was corrupt; far more than the US; Russia has 2 major problems that defined their success in this war. 1, they have an echo-chamber of yes men who weren't correctly advising Putin the probability of success in this War. 2, a shyt load of money that should've been for maintenance and readiness was fukked off by corrupt military men. And because of this, they never could maintain air-superiority in Ukraine.
In identifying why the US is generally successful in their military campaigns, at least in their opening salvos, they always get air-superiority early.
I just can't accept that a military that's supposed to be as advanced as the world thought pre-invasion, couldn't achieve this in a country that's a third of the population, wildly disjointed and corrupt themselves, under-armed, landlocked because they don't have governance over Crimea...and of all things flat...Russia's tank division alone should've been able able to steam roll through Ukraine.
The first indicator to me that this war wasn't going right was they had a 40 mile long convoy rolling into the country. You don't need to be a military mind to know they were going to get picked apart easily.
My fear now is David Petraeus had a good interview on DW recently where he indicated that Ukraine has to join NATO, because any efforts to rebuild Ukraine without any guarantee on the security of that country will never get any outside investment to actually rebuild it. I always knew this war was never about NATO expansion, but real NATO expansion to Ukraine will definitely have irreversible consequences that Putin will be forced to escalate regardless if he was bluffing all along.
