With a passion for tanks’ power, Soviet armies claimed that armored vehicles were capable of fighting independently or cooperating with other armies on the battlefield.
Due to its high firepower, good protection and maneuverability at high speeds on all terrains, highly-armored tanks were often used in the main attack directions, resulting in rapid and powerful breakthroughs, bursting through the enemies’ defensive line and crush the opponent’s resistance.
Therefore, in order to firmly defend their immense territory as well as their allies, and at the same time to win the wars, it was necessary to build highly powerful tanks. When the ammunation race had reached the climax, this requirement became more urgent.
However, with the high cost of the T-80, even though the Soviet Union’s defense budget at the time was very large, it was impossible to manufacture large sufficient quantities of T-80 for the entire demand .
Until the last decade of the 20th century, both T-72 and T-80 became out-dated compared to competitors such as M1A1/A2 Abrams (USA), Leopard 2 (Germany), Leclerc (France) or Challenger (England).
