Russia's new Armata tank has appeared in public for the first time, rumbling down a broad Moscow avenue on its way to Red Square for the Victory Day parade's final rehearsal.

The Russian Defense Ministry last month released photographs of the tank, but its turret was covered with fabric and only the platform was visible. Monday was the first time that the whole tank was shown uncovered.

Russian and some Western military experts say the Armata will surpass all Western versions because of its remotely controlled cannon and the protection it offers its crew. The new tank, which replaces the T-72 and T-90, is supposed to enter service next year.

The military parade takes place on Saturday, the 70th anniversary of the victory over Nazi Germany in World War II.
