Description Tanks go on a three-round route of 6-10 km. During the first round crews fire at targets positioned at a distances of 1,800, 1,700 and 1,500 m. The second round firing is at targets imitating an anti-tank mortar squad and an infantry unit - these targets are at a distance of 600–700 m, and must be engaged with a 7.62 mm coaxial  The third round targeting is at an  and  unit by use of the  12.7 mm remotely controlled at a distance of 1,200 m. Firing misses lead to an extra round, 500 m long. On the final round tanks have to go through various terrain obstacles; a missed or crashed obstacle adds 10 seconds to the crew's final timing.
