7.1 Patrol Techniques & Tactics

Why Patrol Techniques Matter on the MPOLE

Quick Answer: Effective patrol blends visibility, information, and tactics. Missouri peace officers prevent and detect crime, handle Be-On-the-Lookout (BOLO) information, prioritize calls by threat to life, use cover rather than mere concealment, and adapt techniques to both dense cities and rural counties—always within agency policy and constitutional limits.

Patrol is the backbone of Missouri street policing. Within the Class A academy’s Technical Studies block (hundreds of hours covering patrol, traffic, investigations, and reporting), patrol and jail-related instruction commonly accounts for a substantial share—often framed in curriculum materials at roughly the ~56-hour order of magnitude for patrol/custody themes, depending on academy packaging. The written Missouri Peace Officer License Exam (MPOLE) tests whether you understand why officers patrol certain ways, how they prioritize risk, and what safety concepts govern approaches—not every radio code of a single agency.

Preventive vs directed patrol

Preventive patrol puts marked units (or visible foot officers) in the community so would-be offenders cannot predict when police will appear. It supports traffic enforcement, business checks, and informal community contacts.

Directed patrol concentrates resources where crime or disorder is concentrated—for example, a Kansas City or St. Louis corridor with repeated robberies after midnight, a Springfield apartment complex with recurring fights, or a rural county stretch of highway with crash clusters. Directors use crime reports, CAD call history, intelligence, and citizen complaints. MPOLE-level takeaway: random presence alone is not a strategy; officers should know why they are in a sector at a given time.

Area knowledge (your sector is a testable asset)

Strong officers know:

• Street layouts, dead-ends, alleys, and escape routes
• Major businesses, schools, hospitals, and night venues
• Chronic problem addresses (bar fights, drug complaints, DV locations)
• Natural and man-made barriers (rivers, rail lines, gated complexes)
• Local resources (towing, fire/EMS staging, backup agencies)

Missouri mix: An officer in downtown St. Louis faces multi-story buildings, dense traffic, and multi-agency radio traffic. An officer in rural Bootheel or Ozark counties may cover long response distances, limited street lighting, sparse backup, and agricultural or timbered terrain. Area knowledge shortens response time and improves approach safety in both environments.

Exam framing: If a scenario asks what most improves an officer’s ability to respond safely and recognize suspicious activity in a beat, the best answer is often familiarity with the area and its patterns, not a single gadget or random drive-through.

BOLO Handling

A BOLO (Be On the Lookout) alerts units to a person, vehicle, or hazard. Effective handling:

1. Capture critical elements: name/aliases, physical description, clothing, weapons, vehicle (make/model/color/plate/damage), last direction of travel, crime type, and officer-safety notes.
2. Acknowledge and search intelligently: cover likely escape routes, not random spirals that miss the path of travel.
3. Confirm before committing: partial plate matches and similar clothing produce false positives—verify details before high-risk contact when time allows.
4. Update dispatch: when you locate, lose, or develop new information.
5. Do not create a second crime scene: reckless driving to “catch up” to a BOLO vehicle can endanger the public more than the original incident.

Trap: Treating every BOLO as a green light for a high-speed chase. Pursuit authority is separate (see §7.3) and policy-driven.

Foot vs Vehicle Patrol

Vehicle patrol

• Covers larger areas quickly; essential for rural counties and highway interdiction.
• Provides mobile cover, emergency equipment, and prisoner transport capability.
• Risks: tunnel vision while driving, reduced sensory detail, predictable routes if always the same loop.

Foot patrol

• Superior for community contact, business checks, and dense urban blocks.
• Better observation of odors, sounds, and micro-behavior.
• Limits: slower response to distant calls; officer isolation if backup is far.

Tactical habits common to both: keep the gun hand free when practicable, scan 360°, avoid silhouetting in doorways, control light sources, and maintain radio awareness of other units’ status.

Cover vs Concealment

Night note: Darkness is usually concealment, not cover. Moving from shadow to shadow without solid barriers does not make you bulletproof. Use building corners, vehicles (engine block side), and terrain folds as true cover when the threat is armed.

Calls for Service Prioritization & Backup

Dispatchers and officers prioritize by threat to life, violence in progress, and seriousness. A simplified training hierarchy:

1. In-progress violence / active threat / medical life-threat
2. Just-occurred serious felonies with suspect still nearby
3. Crimes against persons not in progress; major property crimes
4. Lower-priority property, nuisance, and delayed reports

You will not invent a statewide CAD code set on the exam—know the logic: life safety first, then public safety, then property, then quality-of-life.

When to request backup (awareness level)

Request or wait for backup when:

• Multiple subjects or a known violent offender
• Weapons involved or high probability of weapons
• Domestic violence with unknown dynamics
• Building searches / structure clearances
• Large crowds or bar-closing disorder
• Rural response where one officer is isolated for long periods

Pride is not a tactic. Early backup requests are professional risk management, not weakness. Missouri rural agencies often rely on mutual aid—know how to call for it under your training and policy model.

Building Searches Overview (Structure Clearance Awareness)

Full tactical team room-clearing is a skills block beyond pure book knowledge, but MPOLE expects awareness-level principles:

• Treat unknown-occupancy structures as unknown risk until proven otherwise.
• Prefer two-officer (or more) searches when available; announce when policy/tactics call for it (e.g., warrant service with knock-and-announce rules vs stealth for certain high-risk entries—follow training).
• Control thresholds (doorways are fatal funnels); slice the pie; do not rush past uncleared space that can shoot you from behind.
• Communicate: contact/cover roles, “clear” calls, and suspect locations.
• Preserve evidence when the mission is investigation after the structure is safe.

Residential vs commercial: Homes carry heightened Fourth Amendment sensitivity (warrant/exception rules from earlier chapters). Tactically, both can hide armed subjects—legal authority and tactics must both be correct.

Night / Low-Light Considerations & Missouri Context

Most serious street violence and many DWI contacts occur in low light. Training themes:

• Light discipline: use flashlight/weapon light deliberately; avoid constant backlighting that silhouettes you for adversaries.
• Identify before you act: low light increases misidentification risk—verbal commands and visual confirmation matter.
• Vehicle lighting: high beams and takedown lights can create a wall of light but also create deep shadows—know your equipment’s limits.
• Rural darkness: fewer ambient lights, longer distances, wildlife and farm equipment hazards on roadway response.
• Urban night: crowds, multiple light sources, reflections, multi-story threats.

Putting it together on a Missouri shift

A directed-patrol hour on a problem block, a BOLO for a stolen truck last seen on I-44, a priority-one domestic with backup staged, and a low-light commercial alarm check all demand the same underlying skills: information, prioritization, cover, communication, and area knowledge. Those are the concepts the academy Technical Studies block builds and the MPOLE probes with scenario-style items.

Common MPOLE traps

• Confusing concealment with cover
• Treating preventive and directed patrol as identical
• Chasing BOLO vehicles without policy/safety analysis
• Ignoring backup needs to “handle it alone”
• Using daylight approach habits unchanged at 0200 hours
