Certain members of OS have System Administration access, which overrides the permissions system and will allow them to provide support to Army units. These members will be able to make changes that you request to the units under your command, including changes to call-signs below you, password changes, and any other help you require. Changes that require approval of those above you in the CoC will require this approval before the changes can be done. Remember that in the case of member movements, promotions and awards, those above you in the CoC should be approached first, and unless there is a bug in the system, should be able to resolve the issue. If needed, you can contact support.
