Military ranks distinguish officers, ORs and conscripts. They also show a soldier's responsibility and command.
You may have heard the phrase "rise through the ranks". The military is known for its system of order and command, in which military ranks are fundamental.
Out in the field and in battle, commands and information must be delivered quickly, and the recipients must understand them correctly. To ensure this, we need clear and indisputable command structure and lines.
The Norwegian Armed Forces have two career ladders for its military personnel: one for officers, and one for specialist officers (OR, other ranks). The two career ladders are equal, but each has its own system of ranks and insignia.
