Police organizations are paramilitary in organizational structure that define leadership and management hierarchy. Insignia on police uniforms are visible displays of identification designating that officer's rank within the department. This visible insignia allows other officers, other agencies, the public, and the media to identify who is in charge, or has leadership and management responsibilities.
Police management can be grouped into 3 categories:
- Chief administrative level - Consists of the chief executive officer and his staff. In any police organization, this staff may have various titles such as captain, assistant chief, major, etc. and is usually above the rank of lieutenant.
- Command level - Consists of those positions who have authority over the line and staff functions of the organization and are generally those with the rank of lieutenant or above, yet below the administrative level.
- Supervisory level - Consists of those who have limited supervisory duties of line or staff functions and generally are ranking officers below the rank of lieutenant and may have various titles such as sergeant, corporal, supervisor, etc.
