This is the moment Ukrainian troops destroy one of Russia's most advanced tanks which are protected by special reactive armour. The armour on the T-90M is designed to explode when hit reducing the penetrative power of an incoming round. The tank is also protected with a automated defence system which fires smoke grenades when it is 'painted' by a laser beam used by an incoming missile. However, the Ukrainian military released drone footage on a Russian armoured unit which resulted in the destruction of the £4million tank as well as a thermobaric multiple rocket system.
