The situation 1374 – December 23, 2025

1. Russia conducted another large-scale combined missile and drone strike against Ukraine overnight on December 22 and 23, primarily targeting energy infrastructure in western Ukraine.
2. Russian forces conducted a reduced battalion-sized mechanized assault in the Dobropillya direction and a reduced-platoon sized mechanized assault in the Kostyantynivka direction on December 22.
3. Combat footage showing failed Russian mechanized assaults continue to demonstrate that Russian forces have been unable to restore mechanized maneuver to the battlefield.
4. Russian gains likely will continue to be constrained to a slow foot pace, and any sudden Russian operational-level breakthrough remains unlikely.

6. Ukrainian forces recently advanced near Kupyansk and Pokrovsk. Russian forces recently advanced near Pokrovsk and in the Kostyantynivka-Druzhkivka tactical area.
