Implementation of Green was the responsibility of "General der Artillerie" Leonhard Kaupisch, commander of the German Fourth and Seventh Army Corps, Army Group B. The originator of the idea for Green is thought to be newly promoted "Generalfeldmarschall" Fedor von Bock, Army Group B. Bock had operational command for the western flank under Operation Sea Lion. Once collated, thirty-two copies of Green were distributed as "Top Secret" on 8 August 1940 to the German High Command; a number of copies survived World War II.
