Red Dwarf/Space Corps
The crew of the Red Dwarf are members of the Space Corps and subject to its rules and regulations. Members can hold various ranks such as catptain, first technician, second technician, etc.
The rules of the Space Corps range from the mundane to the bizzare. They are all enumerated to make citations easier. For example, Space Corps Directive 195 states that in an emergency power situation, a hologramatic crew member must lay down his life in order that the living crew members might survive.
