He fought in Operation Barbarossa, the German invasion of the Soviet Union, and claimed his first aerial victory on 8 August 1941. He received the Knight's Cross of the Iron Cross following his 53rd aerial victory. Accumulating further victories, he surpassed the century mark in October 1942 for which he was awarded the Knight's Cross of the Iron Cross with Oak Leaves. In November 1942, his unit was transferred to the Mediterranean theatre in support of the Afrika Korps. There, Reinert claimed 51 victories against the Western Allies. In August 1943, he was appointed Staffelkapitän (squadron leader) of 1. Staffel (1st squadron) of JG 77, and in February 1944 the 8. Staffel of Jagdgeschwader 27 (JG 27—27th Fighter Wing) based in France. Reinert was then appointed Gruppenkommandeur (group commander) of IV. Gruppe (4th group) of JG 27 and, credited with 174 aerial victories, received the Knight's Cross of the Iron Cross with Oak Leaves and Swords on 30 January 1945. He then received conversion training to the then new Messerschmitt Me 262 jet fighter and was posted to Jagdgeschwader 7 (JG 7—7th Fighter Wing), an all-jet fighter wing.

Passage:In October 2013, it was reported that Cowell may return to the UK version of The X Factor for series 11 in the place of Gary Barlow, and on 7 February 2014, his return was officially confirmed. This resulted in the cancellation of the US version after three seasons by Fox. He joined judges Louis Walsh, Cheryl Fernandez-Versini, and new judge, former Spice Girls member Mel B, who replaced Nicole Scherzinger. For his eighth series, he was given the Over 25s category. On 13 December, Ben Haenow and Fleur East reached the final two, which meant that Cowell was the winning mentor for the first time since series 3 in 2006, when he had both Leona Lewis and Ray Quinn in the final. Haenow became the eleventh winner on 14 December. In March 2015, it was announced that Cowell would return to the X Factor for its twelfth series along with veteran judge Cheryl Fernandez-Versini, and newcomers Rita Ora and BBC Radio 1 DJ Nick Grimshaw.
