Please read. A presentation by Sam Gardner, who is a retired USAF colonel and taught strategy at the National War College, Naval War College and Air War College. Its on a possible use of Russian tactical nukes in Ukraine, and how to respond. Best I've seen on the subject.
Opening summary (these are my summaries--apologies to Sam if I paraphrase wrongly), Russian tactical nukes would basically be to kill civiliansi in a city (Kyiv) more than effect the Ukrainian armies
If used, these weapons would have effect in an area of approx a circular kilometre from airburst
Basically the damage they could inflict on a military airbase--somewhat limited in terms of equipment except close to the airburst.
Putting the damage in context in comparison to an airfield in Latvia or Talinn, the capital of Estonia
Here is what would happen if the Russians used one over the center of Kyiv.
Conclusion. The damage a Russian tactical nuke would do to Kyiv is basically the same as their terror attacks are doing now. NATO would not have to respond with nuclear weapons to retaliate proportionally.
Definitely thought this was worth sharing and appreciate Sam sending it to me.
Most people get the importance of this, but have seen 2 responses that make no sense. 1st is that it is to encourage Ukrainians to keep fighting if they are attacked by these (this is preposterous). 2nd that it calls for too weak a response by not using nukes against Russia.
Not having to get involved in a full nuclear war because the Russians use a tactical nuke on Ukraine is not a bad thing--for Ukraine or the world.
I never thought a paper saying you don’t have to respond to a tactical nuclear usage by escalating to a greater nuclear war (and that’s what it would be as the US doesn’t have such small devices) would get people so upset.
This was not a call to do nothing,But to consider other options such as an overwhelming conventional response. People seem keener than I would like to climb the nuclear ladder and I think it’s worth thinking about something else. That’s all.

Speaking of logistics, this is what seems so poorly conceived in the Russian operations, they are funnelling the supplies for 5 or so different advances all through one series of roads they don’t safely control and which all converge in one town, which is vulnerable
Here is the key transport convergence on the town of Kupiansk (circled in black) Ukrainian forces are actually not that far away (20kms or so) if they can utilise the ranged weapons they have been asking for. Image

Interesting comparison by @paulkrugman which points out the great problem the Russians would face if they make major advances. With an army the size of Robert E Lee’s in terms of soldiers, how does is secure any territory it seizes (or its own vast rear areas)
Seems that the Russian army is built to take objectives but is poorly conceived to take them. Even then it looks very small to take significant objectives if the intelligence estimates are right.
The @isw in its most recent update of just a few hours ago also thinks the Russians will struggle making significant advances with the army Russia now has in Ukraine. Image

Final comment on this from a numerical perspective, as things are quite confused now. If this intelligence is right, that Russia has 76 BTGs in Ukraine, it has to be said its not alot to launch a major offensive.
To cover everything from Kharkiv to Kherson, leaving out Mariupol, Russia has only 64 BTG, as the Pentagon also estimates 12 Russian BTG are tied down with the Mariupol siege.
64 BTG at maximum strength could be 64k soldiers--though its hard to imagine that this is actually the numbers of soldiers the Russians have considering that many of these units have been fighting for 7 weeks now.

Some really interesting evidence from the Pentagon briefing today as reported by @JackDetsch which sheds light on how the Russian build up is going, how many losses they have suffered, and the ongoing battle of the Donbas.
First, The Russian build-up now is now occurring. Before today the number of Russian BTGs the Pentagon was estimating were in Ukraine had actually dropped significantly. Now we have a hard number 76, 11 of which entered Ukr over the past days.
Much of these new formations, with artillery, are heading for the Donbas. Other hard figure, there are 22 BTGs undergoing refit outside of Ukraine (mostly one assumes from the Kyiv assault)

Im no Russia expert, but I have a hypothesis that when policy makers and politicians in Russia publicly speak about Ukraine or the ‘west’ today, they are actually holding a mirror to Russia and describing what they see at home.
Take this interview with Sergei Karaganov, a major figure in what passes for foreign policy analysis under Putin. globalaffairs.ru/articles/proti…
It’s classic projection. Ukraine, which is actually performing so effectively in the war, is shown as a weak state, with a disorganised and useless chief executive which has suffered from 30 years of misrule. Image

A quick thread on the air war (will expand this later as I think it’s so important) but thought I would put up this video, because it seems to me to show the Russians doing something they rarely are, but which they regularly should.
Any idea what it is? In this case the Su-25 are actually flying in tandem (one with a wingman). Most of the videos I’ve seen (and people please send more in if you have them) have solo Russian fixed wing aircraft, flying in and out on a specific mission.
