On 19 October 1940, Wick was promoted to Major and appointed Geschwaderkommodore (wing commander) of Jagdgeschwader 27 (JG 27—27th Fighter Wing). He had no ambition to leave his Gruppe in JG 2 "Richthofen" and, after giving the matter some thought, asked Göring to let him remain with his Gruppe instead. The next day Göring revoked his decision and gave Wick command of JG 2 "Richthofen". At 25 years of age, he thus became the youngest Major and Geschwaderkommodore in the Luftwaffe. Major Wolfgang Schellmann, who had commanded JG 2 since the beginning of September 1940, was placed in command of JG 27 instead of Wick.
