Commander of Ukraine's Joint Forces Serhiy Nayev is confident in the Ukrainian army's victory.

The Armed Forces of Ukraine are ready for all forms and methods of fighting, including offensive operations.

"The Joint Forces are ready for all forms and methods of warfare," Commander of Ukraine's Joint Forces Serhiy Nayev said on Channel 1+1 when asked whether Ukraine is ready for an offensive to retake Russian-occupied areas in Donbas, eastern Ukraine, the TV news service TSN reported.

"I wouldn't be a commander and my subordinates wouldn't be soldiers of the Joint Forces if we were not ready for all forms and methods that combat suggests in general," he said.

As UNIAN reported earlier, Chief of the General Staff of Ukraine's Armed Forces Gen. Viktor Muzhenko says Russia is completing the formation of its strike force on the border with Ukraine, which together with special-operations units will form the base for the Kremlin's invasion fist.

"Russia is completing the formation of the strike groupings on borders with Ukraine, which, jointly with spec-ops units – according to the Kremlin strategists – will form the base of their invasion forces," he said on March 3.
