What is a T-72B3 main battle tank?
The T-72B3 main battle tank is a relatively new Russian upgrade of their old T-72B tanks.
Military experts saw it as a cheap way of adding new technology and weapons to the same old chassis of the T-72B, with each upgrade costing around £250,000.
Improvements include a new engine, gunner’s sight and fire control system.
The first T-72B3 tanks came into use in 2013 and by 2020 the Russian Army had 558 in its arsenal.
They were initially used in the annexation of Crimea in 2014 and later in Syria.
