The Patrol Unit, which comprises the largest single component of the Department, provides uninterrupted 24-hour service to the City of Carrollton. In order to address the demands for service, the Patrol Unit relies upon a system of resource management whereby the City is divided into four (4) quadrants to facilitate and maximize patrol. The Patrol Unit is also divided into four (4) shifts, each being supervised by a Sergeant and at least one Corporal, who oversee the day-to-day operation of the shift.
