I'll go ahead and throw the bucket of cold water on this one. Anyone memeing the countdown as Russia running out of everything is doing it wrong and I will join in laughing at them, because the original 10-day countdown was a prediction from a retired 3-star (making the usual concession that he could be wrong), headed to the point where Russia could no longer press the attack effectively. A historical comparison would be when Germany's fuel reserves ran out in the Winter of '41-'42, and from there on was only able to provide supply to move one of its three army groups at any given time. Word on /k/ is that Moscow's own estimate is that they can keep the offensive up to May 9th. My own prediction is that unless the Russians find a way to unfuck their situation, mid-April looks to be when a combination of supply issues and Ukrainian mobilization bogs them down, and if they haven't fixed their shit by mid-June, they're going to be down to a table full of options they'd really rather avoid taking.
