MARINE CORPS , IMPERIAL TERRAN : The senior Imperial service , the ITMC was founded by Emperor Chang on 10 November 2128 , though he established the Empire itself and took the Throne on 22 January . The date was deliberately chosen to coincide with the birthday , 353 years earlier , of the United States Marine Corps ; the Navy and the Administrative Service were founded one week later , replacing Solar Federation services which were then disbanded . Emperor Chang had retired from the USMC at the rank of Major General after twenty-five years ' service , and thought it only fitting that the ITMC -- a great majority of whose first officers and NCOs came from the USMC -- continue the history and traditions he thought invaluable . He also instituted a new tradition at that time : at 1000 hours , Palace Standard Time , on 10 November of every year , the Sovereign @self publishes the Birthday Article to every Marine post and shipboard detachment . While there have been many changes , the ITMC retains things like the dress blue uniform and Marine Emblem which make its lineal descent from the USMC obvious . The dress blue uniform -LRB- with the USMC male version used by both sexes -RRB- is essentially unchanged ; the ITMC Emblem substitutes the Imperial stylized globe for the USMC 's Terran Western hemisphere . -LRB- For non-humans , there are uniform variations based on physical structure ; Traiti , for instance , do not wear headgear except for protection , and the Irschchans , since 2569 , wear a kilt version of any Imperial uniform . -RRB-
