Near Unna, one "Jagdtiger" climbed a hill to attack five American tanks 600 meters away, leading to two withdrawing and the other three opening fire. The "Jagdtiger" took several hits but none of the American projectiles could penetrate the thick frontal armor of the vehicle's casemate. However, the inexperienced German commander then lost his nerve and turned around instead of backing down, thus exposing the thinner side armor, which was eventually penetrated and all six crew members were lost. Carius wrote that it was useless when the crews were not trained or experienced enough to have the thick frontal armor facing the enemy at all times, if possible, in combat.
