The officers of the Patrol Division are the primary tool of the department to respond to calls for service, investigate criminal actions and deter and dismantle criminal activity within the city. This is accomplished through dynamic patrol tactics, proactive policing, utilizing the Community-Oriented Policing philosophy, in combination with the use of advanced technology and equipment. Patrol officers are assigned to specialized units such as traffic investigation, SWAT, bicycle patrol, and Field Training Officers.

Field Training Officers (FTO)

A number of the patrol officers are also assigned to the FTO program and are responsible for training new officers to the Department's standards. All of these training officers must complete training through the State to qualify and become certified as a Training Officer.

Special Weapons and Tactics (SWAT)

The Forney Police Department SWAT team's primary mission is to respond to incidents such as barricaded persons, hostage situations and other instances that require special skill, equipment and training. In addition, the SWAT team also executes search warrants and arrest warrants that are deemed "high risk" with a possibility of armed resistance.

In addition to their regular assigned duties, SWAT personnel train each month on a variety of tactics including dynamic assaults, buy-bust, downed citizen/officer rescue and hostage rescues. Training is also provided by the Texas Tactical Police Association, I.A.C.P., and other state and national organizations.

Officers assigned to this team must have a minimum of at least one year with the Department. They must demonstrate a high proficiency in firearms as well as physical condition. All officers selected must complete the 50 hour basic SWAT course mandated by the state and complete a one year probation once selected.

Criminal Investigation Division

CID is tasked with the responsibility of thoroughly investigating all criminal incidents requiring follow-up investigations reported to the agency and identifying criminal trends and patterns to reduce the criminal activities within the City. To these ends, Detectives are divided into the specific units detailed below to identify, arrest, and present offenders to the judicial system. Investigators work cooperatively with citizens, officers and investigators from other divisions, City personnel, and other local, state and federal agencies to accomplish this goal.
