Russia's Tigr armoured personnel carrier has been transporting Russian soldiers across the battlefields for 10 years now. The Tigr can carry 10 soldiers in their full gear safely across rough terrain.
However, Russia's military has now turned Tigr into something a lot more terrifying. The Tigr can drive itself and has an extra attachment in the form of a big 30-mm automatic gun attached to its roof.
The Tigr is no longer a docile armoured pussy cat but is now a Russian tiger you don't want to meet on the other side of any battlefield. It can move and fire when commanded by its operator and also identifies and tracks targets on its own.
