Can think those cluster bombs be used to clear minefields?
Yes, it's one of the things they are used for.
You can see how the Ukrainians need them. They have been having trouble with minefields and Russians-in-the-hole. Two things cluster bombs are good at.
No idea what but Russia is up to something - ever since the Wagner revolt but especially last few days a big up tick in military transport planes moving about and government/military special purpose plane flights - some of them appear to be practise or maintenance flights. Not sure if a reaction to the whole Wagner thing so they are better prepared in future and/or to try and prevent any further fragmentation of Russia, preparation because of a potential event at ZNPP or something else entirely - doesn't seem to be focussed on a response to the Ukrainian counter-attack(s).
I'd hazard most likely is the whole thing with Wagner has panicked them a bit and this is attempts to better protect themselves from such things in future, I can't see any public events it might be preparations for, etc.
Agreed. Something is going on.
