Warrant officers (WOs) and chief warrant officers (CWOs) in the US military rank below officers but above officer candidates and enlisted servicemen. The first warrant officer rank, WO1 does not have a "commission" associated with it, instead having a "warrant" from the secretary of the army.
Level of measurement or scale of measure is a classification that describes the nature of information within the values assigned to variables. [1] Psychologist Stanley Smith Stevens developed the best-known classification with four levels, or scales, of measurement: nominal , ordinal , interval , and ratio .
Ordinal data is a categorical, statistical data type where the variables have natural, ordered categories and the distances between the categories are not known. [1]: 2 These data exist on an ordinal scale, one of four levels of measurement described by S. S. Stevens in 1946.
The main difference is in the commissioned officer ranks, where the US system recognizes two grades 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).
In statistics, ranking is the data transformation in which numerical or ordinal values are replaced by their rank when the data are sorted. For example, the ranks of the numerical data 3.4, 5.1, 2.6, 7.3 are 2, 3, 1, 4. As another example, the ordinal data hot, cold, warm would be replaced by 3, 1, 2.

The commissioned officer ranks of the United States Army can be split into three categories, from highest to lowest: general officers, field grade officers and company grade officers. [1] General officers encompass the ranks from brigadier general up. [1] Field grade includes major, lieutenant colonel, and colonel. [1]
Pay grades [1] are used by the eight structurally organized uniformed services of the United States [2] (Army, Marine Corps, Navy, Air Force, Space Force, Coast Guard, Public Health Service Commissioned Corps, and NOAA Commissioned Officer Corps), as well as the Maritime Service, to determine wages and benefits based on the corresponding military rank of a member of the services.
