A quick primer on logistics for those who are interested. In the case of war you can think of logistics as a series of interconnected transportation methods to bring important equipment, supplies, personnel from point A to point B.
There are normally 3 means of transport for a large land war such as we are seeing; truck, train and aircraft. For large Russian armies, the interaction of truck and train is usually the most important, which air supply more limited to specialist operations.
By far the most efficient form of movement is rail, which is why it is favoured (all those flat rail cars you seeing carrying heavy vehicles). Trains are therefore the key vehicle to establish the large depots and bases from which the invasion was launched.
Once you move forward, however, the truck takes over (unless you amazingly enough capture and can operate a fully functioning rail line in the invader country). Only trucks can carry the enormous quantities of everything the invader needs.
This is why most armies have many more trucks than anything else. However trucks present significant challenges themselves. They need regular, high quality maintenance, put heavy strain on their own fabric (tires for instance) and can be easily damaged compared to tanks etc
So the truck is crucial, but you need lots of them and they must be protected and maintained. And this is the challenge we are seeing played out. Take out the trucks and an army stops. Protect your trucks and it moves.
Hope that helps

You can almost tell the sense of surprise from the US spokesperson about how effective the Ukrainian air defense systems have been (or conversely how relatively ineffective the Russians have been in taking them out).
Concentrating on Kyiv, setting up supply lines back to the east to support that drive. Trying to take the city of Sumy which seems to be important to get supplies to the Kyiv operations
When one sits back and looks at what Russia/Putin has done to damage themselves in this invasion it is stunning. Maybe without parallel for a country in such a short time? All in the name of brutalizing its neighbor. The steps when you add them up are unparalleled
1) by forbidding the sale of foreign currency for SIX months, the Russian government is admitting that their own currency has no value on the open market. barrons.com/news/russia-su…
2) The Russian stock market remains closed (has anyone seen any plans for reopening?). As admission that the entire market is close to worthless. wsj.com/livecoverage/r…
Two different narratives emerging about the situation around Kyiv. One is that a major offensive is about to begin (as early as tonight). The other is that the city is still far from encircled and Russian troops are still not ready.
This Institute for the Study of War released yesterday says the Russians are ready to start their major assault with 24-96 hours understandingwar.org/backgrounder/r…
Here is the @tom_bullock_ report saying that the Russians are still being held in the suburbs.
A tweet thread on what a Russian 'victory' would look like, and why it is difficult to imagine unless a significant number of breaks go their way and the Ukrainian people actually dont have a lasting sense of national identity (which seems unlikely).
There has been some discussion and evidence that Russia might be recalibrating away from taking all of Ukraine (which clearly was Putin's preferred plan at the start) to now trying to annex more of Ukraine, part in the south and east.
Here is one of the best discussions of a possible Russian southern strategy aimed at taking the black sea coast.
Some ideas on the state of the war in Ukraine two weeks in, where it might be headed, and why it remains an unwinnable war for Russia which the Russians would be best to end soon or they face an extraordinarily bleak future. And why this is a lesson on the stupidity of war.
The first thing to see is that for almost a week now, the Russian Army has been almost entirely inert. See the UK MODs maps yesterday and March 2. This is a sign of total strategic failure.
Yes there is the bizarre thin thrust down the roads from Sumy to Kyiv. However that looks more precarious than anything else. And interestingly that has stalled in the last few days (supply issues and Ukrainian resistance one imagines). Its more likely a target than a threat
