 Hubbard attributed his service in the regiment to his need for " a little recreation . Life was dull . Fellow came up to me and he says , ' The Marine Reserves are organizing a twentieth regiment . Why don 't you come down ? ' " He made the dubious claim of being rapidly promoted to the rank of First Sergeant ; Hubbard later explained his unusually rapid promotion as being due to his unit being newly formed and his superiors being unable to " find anyone else who could drill . " He stated that he was rated ' excellent ' for military efficiency , obedience and sobriety . On October 22 , 1931 , Hubbard received an honorable discharge along with the annotation " not to be re @-@ enlisted . "
