Ranks and insignia of NATO affiliated nations are combined military ranks and insignia used by the member countries (and other affiliated nations) of the North Atlantic Treaty Organization.
The rank scale is used for specifying posts within NATO.
NATO maintains a "standard rank scale" which is also known as a "standardized reference system" in an attempt to match every member country's military ranks to corresponding ranks used by the other members. [1] The NATO rank reference code categories were established in a 1978 document entitled STANAG 2116 (formally titled NATO Codes for Grades of Military Personnel).
NATO rank codes are not the same as military ranks (US Army examples: Private, Corporal, Warrant Officer 1, Chief Warrant Officer 5, Captain, Major, Colonel, etc.) and military pay grades (US military examples: E-1, W-1, CW-5, O-1, O-1e, O-10, etc.). They are rank codes that allow for interoperability among NATO member nations.
OF-1 – OF-10 (lowest rank code to highest) are used for commissioned officers: [1]
In US Forces the Warrant Officer is a separate and distinct category of officers. This officer rank and precedence is below those of officer personnel, but above that of non-officer personnel. Warrant Officer grades are as followss: [2]
The warrant officers are the highest other ranks in British Armed Forces and Canadian Armed Forces. [3]
OR1–OR9 (lowest rank code to highest) are used for other ranks: [1]
At the same time, there are exceptions, for example:
This is not a new feature: it was present in previous editions of STANAG 2116, but was sometimes overlooked.
The numbers in the system broadly correspond to the U.S. uniformed services pay grades, with OR-x replacing E-x. The main difference is in the commissioned officer ranks, where the US system recognises two ranks at OF-1 level (O-1 and O-2), meaning that all O-x numbers after O-1 are one point higher on the US scale than they are on the NATO scale (e.g. a major is OF-3 on the NATO scale and O-4 on the US scale).
