context_page_description: The T-84 is a Ukrainian main battle tank, a development of the Soviet T-80 main battle tank introduced in 1976. The T-84 was first built in 1994 and entered service in the Ukrainian Armed Forces in 1999. The T-84 is based on the diesel-engined T-80 version, the T-80UD. Its high-performance opposed-piston engine makes it one of the fastest MBTs in the world, with a power-to-weight ratio of about 26 horsepower per tonne. The T-84 Oplot is an advanced version incorporating an armoured ammunition compartment in a new turret bustle; ten of these entered Ukrainian service in 2001. The T-84-120 Yatagan is a prototype model intended for export, mounting a 120 mm gun capable of firing standard NATO ammunition and guided missiles.
