A sub-officer was an Imperial non-commissioned officer.
Sub-Officer is a term used in many military forces used to indicate ranks below commissioned officers. Sub-Officer is equivalent to the term NCO in the Commonwealth and USA. Historically armed forces using the term sub-officer have used it to refer to more senior non-commissioned ranks, typically from sergeant upwards, but often the term now covers all non-commissioned ranks. There is also a specific rank of "sub-officer" in some armed forces and in the UK Fire and Rescue Services.
