A "Geschwaderstab" was essentially a Headquarters Unit ("Stabschwarm") for the entire wing. There were headquarters units also at gruppe level. Initially when JG 1 was re-formed in Jever, it was constituted as a Regional Fighter Command ("Jagdfliegerführer" 2) on 30 November 1939 with an intention to co-ordinate with navy ("Kriegsmarine") flak and signals units. This autonomous command defending the coastline was placed under "Oberstleutnant" Carl-August Schumacher. "Geschwaderstab" JG 1 (Stab. JG 1) was also alternatively called "JG Nord" or "JG Schumacher" and was equipped with Bf 109 D and E variants.
