T-72M1K1

The T-72M1K1 is a testbed tank that was modified by the Finnish Army to improve its performance and suitability for Finnish conditions.

The new engine was a V-46-6 diesel engine that produced 780 hp, which improved the mobility and fuel efficiency of the tank.
The T-72M1K1 also had:

• a laser rangefinder
• a ballistic computer
• a stabilized gunner's sight
• a thermal imager for better accuracy and night vision.

The tank was also fitted with ERA (explosive reactive armor) blocks on the turret and hull to increase protection against anti-tank weapons.
The T-72M1K1 was one of the most advanced versions of the T-72 in service with any country.
