In addition to the T-72, Russia has also deployed advanced tank support combat vehicles, known as BMPTs, in the conflict.
These vehicles were seen in the Donbas region, which has become the main battlefield of the war.
Russia has lost a significant number of tanks in the war, with reports suggesting that they have lost upwards of 400 tanks, about a third of their total tank force on the ground in Ukraine.
Additionally, Russian tank crews rarely survive the destruction of their tank, so each of those losses equates to almost three men killed.
The move to equip Ukraine with main battle tanks follows months of lobbying from Ukrainian President Volodymyr Zelensky.
