- O-number and W-number in US forces denotes pay grade.
- US Warrant Officers are technical and tactical leaders who
specialize, throughout an entire career, in a specific technical
area, and usually have no command authority except in their
specialty, e.g., as an aircraft pilot. Their benefits are roughly
comparable to those of commissioned officers. USAF does not
currently have Warrant Officers, but US Army has several as
helicopter pilots.
