Marine Ranks

Ranks and Command

While rank is to be respected at all times, during normal operations, command is determined by position. If someone is given conflicting orders, they must give priority to those of their department’s superiors. The Commanding Officer’s authority is absolute and all personnel aboard must defer to his authority with the exception of specially dispatched officials from High Command or other Diplomatically Immune officials. The following section determines whose orders crew members are bound to follow.

  • Enlisted: Enlisted personnel must obey any lawful order given to them by commissioned officers, with priority given to the CO, XO and those of their department. Additionally, enlisted combat marines must obey the orders of enlisted personnel with higher rank than theirs.
  • Officers: Officers have authority over their own department but must obey the orders of the CO and XO or the person in command of the operation.
  • Civilians: While in the AO(Area of Operation), all civilians must comply with orders given by military personnel. On ship, Civilians are under the direct authority of the Command and Security departments. They must obey their orders, but are not required to obey the orders of any other military personnel unless they are placed in a department, in which case they are also under the authority of all crewmembers of that department.

Succession/Chain of Command

Should the Commanding Officer become unfit to command, be it due to absence, SSD, Death, imprisonment or other circumstances, the next person on this list assumes command. The person in command of the operation does not assume their superior’s rank, title or powers such as access changes or ship modification, but other personnel must follow their orders that pertain to directing the operation such as construction or requisitions orders.
