Gerhard "Knall" Koall (7 June 1912 – 27 April 1945) was a Luftwaffe ace and recipient of the Knight's Cross of the Iron Cross during World War II. The Knight's Cross of the Iron Cross was awarded to recognise extreme battlefield bravery or successful military leadership. Gerhard Koall was killed on 27 April 1945 after being hit by Soviet anti-aircraft fire near Anklam. During his career he was credited with 37 victories, 35 on the Eastern Front and 2 during the Invasion of Yugoslavia.

Career
Koall was born on 7 June 1912 in Königsberg in the Kingdom of Prussia of the German Empire. Today it is Kaliningrad in Kaliningrad Oblast, the Russian exclave between Poland and Lithuania on the Baltic Sea.

On 23 February 1942, Koall was appointed Staffelkapitän (squadron leader) of 3. Staffel of Jagdgeschwader 54 (JG 54—54th Fighter Wing). He replaced Hauptmann Hans Schmoller-Haldy who had been wounded in combat that day. The Staffel was subordinated to I. Gruppe of JG 54 which was headed by Hauptmann Hans Philipp.

In mid-April 1943, a newly formed Jabostaffel (fighter bomber squadron) was formed and labeled 13.(Jabo) Staffel of JG 54 and placed under the command of Koall.

In late-February 1944, Koall succeeded Hauptmann Siegfried Schnell as Gruppenkommandeur (group commander) of IV. Gruppe of JG 54 after Schnell had been killed in action on 25 February.
