Russia and Ukraine Clash in Evolving Battlefield Tactics.

Ukraine's special forces have shared graphic footage of what appears to be the killing of ten Russian soldiers in a trench in southern Ukraine. The video shows Ukrainian soldiers approaching the enemy's positions from the rear and catching them by surprise. The location and date of the footage are unknown. Ukraine says it has captured an eighth settlement in its ongoing counteroffensive, while Russia denies this. Both sides have suffered high casualties, with more than 4,600 Russian soldiers killed or wounded in the past week, according to Ukraine.
