The Uran-9 unmanned tank - also war-tested in Syria - is seen as capable of ambushing NATO forces.

Russia will use Wednesday’s annual Victory Day parade - commemorating the allied victory against the Nazis in World War Two - to display its latest firepower.

The remote-controlled Uran-9 - with 30mm cannon and antitank guided missiles - will take its first bow in front of Putin and the Kremlin elite.

It is seen as an ambush predator for NATO tanks on a modern battlefield.
