A. 
Supervision. A supervisory officer may be assigned to field or office duties. During his tour of duty, he must closely supervise the activities of his subordinates, making corrections where necessary and commending where appropriate.

Leadership. Effective supervision demands leadership. Provision of leadership shall include on-the-job training as needed for efficient operation and coordination of effort when more than one member or employee is involved.
C. 
Direction. Supervisory officers must exercise direct supervision in a manner that assures the good order, conduct, discipline and efficiency of subordinates. Exercise of command may extend to subordinates outside the usual sphere of supervision if the police objective or reputation of the Department so requires; or if no other provision is made for personnel temporarily unsupervised. This authority shall not be exercised unnecessarily. If a supervisor requires a subordinate other than his own to leave a regular assignment, the supervisor so directing will inform the subordinate's own supervisor as soon as possible.
D. 
Enforcement of rules, etc. Supervisory offices must enforce Department rules and regulations and ensure compliance with departmental policies and procedures.

He shall observe contacts made with the public by his subordinates and be available for assistance or instruction as may be required. A field supervisory officer shall respond to calls of serious emergencies, felonies in progress, assaults and others, unless actively engaged in a police incident. He should observe the conduct of the assigned personnel and take active charge when necessary.
