So I guess the thing to watch for now is when will Ukraine start the next counter offensive?
... I have not heard anything lately on the Leopard 2 training. I did see a news story where some training on them in Spain finished in March.
Overall, we have not heard a lot of specific information to assess how the war is going and where it is headed next, at least that's my impression.
And I am pretty sure this is on purpose: To keep everyone, especially the Russians, nervously guessing.
If that is true, we learn how the Ukrainians and their Western partners are able to control the infornation sphere. In other words, how much of what we heard in the past year has been carefully chosen for our (and their) consumption.
Anyway, to answer: There was an incident recently in Poland of a Leopard apparently having been crashed into by another tracked vehicle (another Leo?), which knocked off the turret. That happened in a muddy field and most probably tells us that there was some sort of training ongoing.
There were also some news reports of Ukrainians being bid farewell in the communities where they had been training - in Norway, in Germany, in the UK. Again, such reports are released for public (including Russian) consumption, so it's not clear hpw much it means.
...Seeing stories about Ukraine running short on Russian anti-aircraft missiles. ...
I saw recent stories of e.g. Germany having sent Patriots, sourcing more Gepard ammo ... things are happening, we just don't get all the details.
Then there is this story of small teams of Ukrainians landing with small craft on the left bank of the Dnipro (or rather a triver island) just north of Kherson, with the impression being suggested they may be controlling a bridgehead, or may be headed to secure the remsains of the Antonovski bridge.
Many commenters think this is a decoy. To keep the Russians nervously guessing and on their cold, muddy toes.
