Something has changed in Ukraine in the past 24 hours. It's armed forces have hit targets first, 150km from the front and now, 230km from the front, inside of Crimea.
The means remain unknown. It could be sabotage, or, since the Anti-Radiation AGM-800D missile has been active there for a few days, it could be drones. It could also mark the arrival of the much expected longer range GMLRS rounds or ATACMS missiles which can strike even deeper. Anti-Radiation weapons means enemy radars can no longer operate and so the skies are uncontested, for practical purposes, if these missiles are on duty.
A few days ago, Russia has accused the United States of being personally involved in the war on account of the far-reaching impacts of some new weapons. US and British aircrafts have been tracked on the Black Sea by OSINT observers, far away from the battles and they are suspected to be acquiring targeting dara which they later pass on to Ukraine.
What all these add up to is that this war is getting bigger and much more decisive and Russia is becoming more of the responding side - and respond it definitely will, which wouldn't take weeks.
