The Operations Division is the largest division in the police department. Officers patrol the City of O'Fallon 24-hours-a-day, seven days a week, responding to most calls for service. The police department responds to approximately 60,000 calls for service annually.
Officers are divided into four 12-hour shifts. Individual shifts are managed by watch commanders, a lieutenant and three supervisors who are sergeants.
The City of O'Fallon is divided into eight geographical areas called sectors. The watch commander will assign officers to each sector. When officers are assigned to particular areas of the city, it provides blanket coverage and enhances quicker response times. It also allows officers to quickly respond to other areas as needed. The patrol division prides itself on providing a quick response and serving the community.
Every officer assigned to the Operations Division utilizes a marked police car - either fully marked or partially marked. This higher visibility of police presence in the community helps make it less likely criminal activity will occur.
