Sergeant (Sgt) is a rank in use by the armed forces of many countries. It is also a police rank in some police services.

A chief petty officer (CPO) is a senior non-commissioned officer in many navies and coast guards, usually above petty officer.
Ensign is a junior rank of a commissioned officer in the armed forces of some countries, normally in the infantry or navy. As the junior officer in an infantry regiment was traditionally the carrier of the regimental colours, the rank acquired the name. This rank has generally been replaced in army ranks by second lieutenant. Ensigns were generally the lowest-ranking commissioned officer, except where the rank of subaltern existed. In contrast, the Arab rank of ensign, لواء, liwa', derives from the command of units with an ensign, not the carrier of such a unit's ensign, and is today the equivalent of a major general.
