Original sentence: During August 1944, a number of Tiger II tanks were captured by the Soviets near Sandomierz and were soon tested by the Soviets at their testing grounds at Kubinka.The testers concluded that the Tiger II posed a lesser challenge than the much lighter and cheaper Tiger I, and were puzzled at the German decision to produce it.The tests revealed the tanks to be severely defective: the transmission and suspension broke down very frequently and the engine was prone to overheating and consequential failure
Edited sentence: During August 1944, a number of Tiger II tanks were captured by the Soviets near Sandomierz and a single tank was soon tested by the Soviets at their testing grounds at Kubinka.The propaganda testers concluded that the Tiger II posed a lesser challenge than the much lighter and cheaper Tiger I, and were puzzled at the German decision to produce it.The stupidity of the tests was revealed when only a single tank was fired repeatedly at close range and the soviet tank crews could not operate the machine sufficiently well, the transmission and suspension broke down very frequently and the engine was prone to overheating and consequential failure
