Russia's top-tier T-14 Armata tanks were used in combat in Ukraine, state media reported.
But then they were quickly "withdrawn from the frontline," a military source told state media.
Armored forces from Russia's southern military district (SMD) "actively used Armata in combat," an unnamed military source told the state-run outlet TASS.
Russia says it has defense systems that capable of countering the anti-tank rockets that Ukraine has deployed so effectively in battle against older Russian tanks.
"The necessary trials of the T-14 tank still continue," another unnamed military source told TASS.
