Ukraine

You mean any Russian, correct?

This is definitely good for Ukraine. Not as good as it could have been had it been real, but still a net positive for them.
Totally

In the short term...RuAF is disjointed. As news filters to RuAF forces, they have to be thinking wait wut? Who running this? Why am I here?

Prigo made it a point to say, publicly, there was lies and corruption that led to Ukraine invasion. Can't keep that tamped down forever. Folks heard that. Others will. Especially those who may get mobilized. Morale has to be very low.

Add in PMC mercs who went along only to see him turn. How does that play out within the ranks?

Meanwhile UAF has plans. RuAF did too...now they have to be somewhat upended. At the very least, communication and purpose has been lost. Initiative too. Bad mix for a fighting force on the precipice of facing major assault.
