Staff Sgt.

Staff sergeant is a rank of non-commissioned officer used in the armed forces of several countries. It is also a police rank in some police services.

In origin certain senior sergeants were assigned to administrative, supervisory, or other specialist duties as part of the staff of a British army regiment. As such they held seniority over sergeants who were members of a battalion or company, and were paid correspondingly increased wages. Their seniority was indicated by a crown worn above the three sergeants' stripes on their uniform rank markings.

In the Australian Army and Cadets, the rank of staff sergeant is being phased out. It was usually held by the company quartermaster sergeant or the holders of other administrative roles. Staff sergeants are always addressed as "Staff Sergeant" or "Staff", never as "Sergeant" as it degrades their rank. "Chief" is another nickname though this is only used for the company chief clerk (in some instances the chief clerk role can be filled by another non-commissioned rank (but not warrant officer) and still be referred to as "Chief"). A staff sergeant ranks above sergeant and below warrant officer class 2.

In the Israel Defense Forces, soldiers are promoted from sergeant to staff sergeant (samál rishón) after 28 months of service for combat soldiers, and 32 months of service for non-combat soldiers, if they performed their duties appropriately during this time. Soldiers who take a commander's course may become staff sergeants earlier (usually after 24 months of service, or one year from becoming a commander). The rank insignia is composed of three clear-blue stripes (as is the rank of sergeant) with an embroidered fig leaf, a biblical motif, in the center of the rank insignia. Staff sergeants get a symbolic pay raise.
