Although sustained travel at road speeds was hardly ever used outside of the Allied response during the Battle of the Bulge, most Hellcat crews found the higher speeds especially useful in a sprint to flank German tanks, which had relatively slow turret traverse speeds, and such maneuvering allowed the tank destroyer crew to direct a shot into the enemy's thinner side or rear armor. The open-top proved an advantage in terms of allowing the TD crews significantly better visibility than their opponents, many of which were German tank destroyers that did not have revolving turrets and were handicapped by poor lateral visibility.
