Patrol Supervision and Field Operations

Patrol Supervision and Field Operations tests command presence: whether a lieutenant can deploy resources, run a radio incident, and keep a scene controlled while subordinates act.

Field command basics

  • Conditions are posted hazards or recurring problems; a supervisor checks whether conditions are addressed at roll call and on patrol.
  • Radio discipline matters: a 10-13 (officer needs assistance) requires a clear location, nature, and direction; a 10-85 is an unusual occurrence requiring notification.
  • Scene management: establish a command post, assign inner and outer perimeter, designate a scribe, and keep the radio channel clear.
  • Use of force: ensure medical aid, supervisor notification, and documentation; do not let the involved officer write the only account.
  • Stop, question, and frisk: review reasonable suspicion, scope, and documentation; correct unlawful practices immediately.

Worked example: A 10-13 reports an officer struggling with a person in a stairwell. The lieutenant should acknowledge, assign responding units to the street entrance, designate a recorder, request EMS, and establish a perimeter-not run to the struggle and leave the radio. After the scene is stable, the lieutenant separates witnesses, ensures the officer's injuries are treated, reviews body-worn camera status, and starts the use-of-force and unusual-occurrence notifications.

Traps

  • Abandoning command to personally engage.
  • Failing to assign a recorder or perimeter.
  • Letting the involved officer control the scene narrative.
  • Missing EMS or injury documentation.
  • Treating a stop as lawful because contraband was found.
