Cannot, resist, to, add, more, challenges... Two tanks, the best of their period, battle face to face. Hit by hit, none penetrated each other's front armor, with one being at risk of fire from his enemy's rotatable turret while the other being immobilized. Neither can flank each other safely. Meanwhile, the ammo rack in each of the tank gets emptier by the minute. Their reinforcements are (not actually) miles away, artillery can't reach them, hell nothing can disturb the duel for the next 10 minutes. But first, YOU MUST NAME BOTH CONTESTANTS.
