Russia has deployed almost 100% of the combat power it pulled to the borders of Ukraine - US Department of Defense

This is reported by CNN with reference to the words of a senior US defense official.

He also noted that Russia launched more than 625 missiles into Ukraine.

While the airspace over Ukraine is still in an inconsistent state, the official said, the US estimates that Ukrainian President Volodymyr Zelensky has "the vast majority of his aircraft" in place, as well as surface-to-air weapons to protect Ukrainian airspace.
