6.2 In-Progress Calls, Tactical Positioning & Contact-Cover

6.2 In-Progress Calls, Tactical Positioning & Contact-Cover

AZPOST Comprehensive Examination Focus: Recruits must demonstrate tactical proficiency in responding to in-progress felony incidents (commercial robbery, residential burglary, violent assault, prowler calls), executing invisible deployment and silent approaches under A.R.S. § 28-624, positioning patrol vehicles for ballistic cover, establishing inner and outer perimeters using the quadrant numbering system with diagonal corner coverage, clearing structures using threshold evaluation and slicing the pie, and executing the Contact and Cover doctrine pursuant to Ariz. Admin. Code R13-4-116(E)(1)(c)(iv).

Responding to in-progress criminal events represents the highest-liability and highest-danger operational environment a patrol officer encounters. Unlike past-occurred cold reports, in-progress calls involve dynamic, rapidly evolving variables: armed adversaries on scene, fleeing suspects, panicked victims, and immediate threats to human life. Tactical success requires replacing emotional urgency with coordinated planning, tactical vehicle positioning, disciplined perimeter containment, and strict division of labor.

1. Tactical Response Dynamics to In-Progress Crimes

When dispatch broadcasts an in-progress felony—such as an armed robbery, burglary in progress, or aggravated assault—the responding officer must immediately engage in pre-arrival tactical rehearsal:

[ CAD Broadcast Received ] ──► [ Route Planning ] ──► [ Invisible Deployment ] ──► [ Perimeter & Contact ]
Review suspect desc.,          Avoid choke points;    Sirens/lights off early;      Containment established;
weapons, flight paths          alternate approach     blackout, noise discipline    Contact/Cover execution

Critical Pre-Arrival Information Gathering

• Continuous CAD & Radio Monitoring: Continuously monitor Mobile Data Computer (MDC) updates and radio broadcasts for suspect descriptions, number of perpetrators, weapon types, and exact location inside or outside the premises.
• Terrain & Flight Path Analysis: Identify potential flight routes, alleys, canal banks (prevalent in metropolitan Phoenix and agricultural Arizona regions), and adjacent major thoroughfares where lookouts or getaway vehicles may be staged.
• Arrival Route Coordination: Coordinate arrival paths with secondary backup units over the radio to prevent simultaneous clustering and ensure multiple angles of arrival.

2. Tactical Response Protocols by Specific Call Types

Different in-progress crimes present unique operational hazards and tactical challenges. Responding officers must adapt their arrival, containment, and engagement tactics based on the specific offense profile:

                              [ Call-Specific Response Architectures ]
                                                 │
    +--------------------------------------------+--------------------------------------------+
    |                                            |                                            |
[ Commercial Armed Robbery ]           [ Burglary in Progress ]                    [ Prowler / Suspicious Person ]
- High hostage/standoff hazard         - Suspects trapped inside structure         - Stealth foot approach required
- Standoff staging; do NOT enter       - Exterior containment BEFORE entry         - Avoid silhouette against windows
- Seal exits; intercept escape phase   - Request K-9 / Air Support (DPS Ranger)    - Check fence lines & dark corners

1. Commercial Robbery in Progress

• Extreme Hostage & Ambush Danger: Commercial robberies (convenience stores, banks, pharmacies) involve armed perpetrators under extreme stress. Rushing into the business transforms a robbery into an active hostage barricade or triggers an immediate close-quarters shootout endangering innocent clerks and patrons.
• Standoff Staging: Officers must stage out of sight of large storefront picture windows. Do not pull into the primary customer parking lot.
• Robbery in Progress vs. Robbery Escape Phase: If the robbery is actively taking place inside, officers hold exterior containment behind cover. The optimal tactical moment to challenge and apprehend the suspect is as they exit the premises, when they are isolated in the open without cover and away from civilian hostages.

2. Burglary in Progress (Commercial & Residential)

• Forced Entry Indicators: Lookouts in idling vehicles, cut alarm wires, broken window panes, forced deadbolts, or propped rear service doors.
• Containment First Doctrine: Never enter an uncleared structure alone or without establishing perimeter containment. Most commercial burglars attempt to hide inside false ceilings, ductwork, or utility closets. Premature entry without containment allows suspects to slip out unmonitored rear exits.
• Canine & Air Support: Request specialized K-9 units for interior searches and air support (AZ DPS Ranger or local aviation) to monitor rooflines and flight corridors.

3. Prowler Calls & Suspicious Persons Around Residences

• Caller Vulnerability: Callers are typically terrified homeowners reporting noises outside bedroom windows or yard gates. Dispatch must instruct the homeowner to remain inside with exterior lights illuminated and doors locked.
• Stealth Foot Approach: Cut cruiser lights and vehicle engine blocks away. Approach the residence on foot along edge boundaries, avoiding concrete walkways that amplify footstep noise.
• Yard Containment: Check fence lines, squeaking latch gates, and listen for neighborhood dogs barking, which telegraphs suspect flight paths. Never step onto illuminated patios or stand directly in front of rear glass sliding doors.

Tactical Response Protocols by Incident Type

3. Invisible Deployment, Silent Approach & Blackout Operations

Invisible Deployment is the tactical discipline of approaching a crime scene in a manner that conceals the police presence until officers have secured dominant tactical positions.

[ 1/2 Mile Out ] ──────────► [ 2 Blocks Out ] ──────────► [ Immediate Block ] ──────────► [ Scene Arrival ]
Deactivate sirens;            Deactivate overhead         Blackout mode: kill           Coast to curb short/past;
coordinate approach           emergency lights            headlights, dim MDC           quiet door latch; radio low

Emergency Equipment De-escalation Under A.R.S. § 28-624

• While Arizona law grants emergency vehicle operation privileges (exceeding speed limits, proceeding through red signals) under A.R.S. § 28-624 when emergency lights and sirens are activated, the statute explicitly mandates that the driver must operate with due regard for the safety of all persons.
• When responding to in-progress felony calls, sirens must be deactivated several blocks or at least a half-mile away from the target location.
• Running sirens directly to the door alerts armed suspects, prompting them to take hostages, ambush approaching officers, or initiate high-speed vehicle pursuits through residential neighborhoods.
• Deactivate overhead emergency light bars prior to turning onto the final approach street to prevent flashing reflections off buildings, trees, and parked vehicles.

The Blackout Approach & Interior Vehicle Discipline

• Blackout Driving: During nighttime operations, extinguish headlights and daytime running lamps (using manual override or parking brake clicks if equipped) upon entering the immediate block. Dim interior MDC screens, dashboard lights, and radio displays to avoid backlighting the officer's silhouette inside the cruiser.
• Arrival Noise Discipline:
  • Stop the vehicle short of or past the target address, never directly in front.
  • Avoid aggressive acceleration or abrupt braking that causes tire squeal.
  • Turn the police radio down to a low audible volume or use an earpiece before exiting the vehicle.
  • Close the cruiser door quietly to the first latch without slamming.
  • Secure duty belt accessories (keys, baton, handcuffs) to prevent metallic clanking while moving on foot.

4. Tactical Positioning of Patrol Vehicles

Where an officer parks their cruiser determines their initial survival options. The patrol cruiser must serve as an asset, not a tactical trap.

                                [ The Fatal Funnel Trap ]
      [ Target House / Front Door / Picture Window ] <─── Primary Fire Arc
                             X [ DO NOT PARK HERE ] 
                             
    [ COVER POSITION 1 ]                                  [ COVER POSITION 2 ]
   Parked 2 doors short;                                  Parked past location;
   Engine block toward threat                             Wheels angled, behind axles

Vehicle Placement Protocols

1. Never Park Directly in Front of the Address: Parking directly in front places the officer squarely within the suspect's primary observation window and field of fire (the "fatal funnel" of front windows and doors).
2. Park Past or Short of the Location: Park at least two to three house lengths short of the location, or pull past the address so the suspect must lean awkwardly backward to view the unit.
3. Angling the Vehicle: Angle the cruiser at a 45-degree angle toward the threat, placing the dense engine block between the officer and the suspected threat location.

Ballistic Cover vs. Concealment

• Cover: Physical barriers that stop, deflect, or significantly degrade incoming firearm rounds.
• Concealment: Physical barriers that shield an officer from visual observation but provide zero ballistic protection against bullets (e.g., wooden fences, bushes, interior drywall, vehicle door sheet metal).

| Patrol Vehicle Component | Tactical Classification | Ballistic Reality & Operational Usage | |:---|:---|:---|:---| | Engine Block & Front Axle | Ballistic Cover | Dense cast steel/aluminum engine block and steel wheel hubs stop most handgun and rifle rounds. Position body behind front axle assembly. | | Vehicle Doors & Body Panels | Concealment Only | Standard automotive sheet metal and interior plastic offer virtually zero resistance to firearm projectiles. Door frames do not stop rounds. | | A-Pillar & B-Pillar Steel Posts | Partial Cover | Reinforced structural steel door posts provide narrow ballistic deflection points, but narrow width makes full body coverage difficult. | | Windshield & Windows | Concealment Only | Safety glass does not stop handgun or rifle fire and creates flying glass spall upon impact. |

5. Perimeter Containment Architecture & The Quadrant System

A disorganized perimeter guarantees suspect escape. Containment must be systematically established before any building entry is attempted.

                     [ Diagonal Corner Containment Architecture ]
                     
                              Side 3 / Charlie (Rear)
                     +---------------------------------+
                     |                                 |
  [ OFFICER A ] ───► | Corner 1               Corner 2 | 
  (Covers Side 1 &   |                                 |
   Side 2 / West)    |       Target Structure          | Side 4 / Delta
   Side 2 / Bravo    |                                 | (Right Wall)
   (Left Wall)       |                                 |
                     | Corner 4               Corner 3 | ◄─── [ OFFICER B ]
                     +---------------------------------+      (Covers Side 3 &
                              Side 1 / Alpha (Front)           Side 4 / East)

Inner vs. Outer Perimeters

• Inner Perimeter: The immediate containment boundary sealing the physical structure or incident scene. Officers deployed on the inner perimeter prevent the suspect from escaping the building, monitor doors and windows, and provide immediate intelligence to the contact team.
• Outer Perimeter: A wider secondary perimeter established around the surrounding neighborhood blocks. Officers on the outer perimeter control civilian pedestrian access, divert vehicle traffic, stage responding emergency medical units, and establish intercept positions to catch suspects who breach the inner perimeter.

The Quadrant Numbering System

Under standard AZPOST tactical naming conventions, structures are identified using the four-side system:

• Side 1 (Alpha): The primary front / address side of the structure facing the street.
• Side 2 (Bravo): The left side of the structure (viewed from the street facing Side 1).
• Side 3 (Charlie): The rear side of the structure.
• Side 4 (Delta): The right side of the structure.
• Corners:
  • Corner 1: Intersection of Side 1 (Alpha) and Side 2 (Bravo).
  • Corner 2: Intersection of Side 2 (Bravo) and Side 3 (Charlie).
  • Corner 3: Intersection of Side 3 (Charlie) and Side 4 (Delta).
  • Corner 4: Intersection of Side 4 (Delta) and Side 1 (Alpha).

Diagonal Corner Deployment & Crossfire Mitigation

• Two-Officer 360-Degree Coverage: In a standard four-sided structure, two officers can provide 100% 360-degree exterior containment of all four exterior walls by deploying at opposing diagonal corners:
  • Officer A takes position at Corner 1 (observing and controlling both Side 1 and Side 2).
  • Officer B takes position at Corner 3 (observing and controlling both Side 3 and Side 4).
• Crossfire Avoidance: By maintaining diagonal positions at the corners rather than directly facing each other across the sides (e.g., Side 1 facing Side 3), officers eliminate backstop hazards and avoid shooting toward one another if a suspect emerges and initiates gunfire.

6. Structure Clearing & Building Search Methodologies

Searching an uncleared building is an inherently high-risk operation. Statistically, officers entering structures during in-progress burglary or robbery calls face maximum vulnerability at entry thresholds.

Threshold Evaluation & Fatal Funnels

• The Fatal Funnel: Any narrow geographic pathway—specifically doorways, hallways, window openings, and stairwells—that restricts officer movement and focuses an armed suspect's attention and fire arc. Officers must never linger, pause, or conduct conversations while standing inside a doorway or hallway.
• Threshold Evaluation: Assessing the entryway from cover outside the room prior to entry. Check for door swing direction, interior lighting, furniture barricades, and deep corner blind spots.

                   [ Slicing the Pie (Angular Clearance) ]
                               Room Interior
                     +─────────────────────────────────+
                     │ Deep Corner             Deep Corner │
                     │                                 │
                     │       Pie Slice 3               │
                     │   Pie Slice 2                   │
                     │ Pie Slice 1                     │
                     +───────   ───────────────   ─────+
                                  [ Doorway ]
                                     / | \
                                    /  |  \
                       Pos 1 ──► Pos 2 ──► Pos 3 (Officer moves in arc)

Slicing the Pie (Angular Search)

• Rather than immediately rushing through a doorway, officers employ slicing the pie (angular clearing).
• The officer stands several feet back from the doorway (maximizing standoff distance and cover from the exterior wall).
• The officer moves laterally in an arc, clearing the interior room in narrow, incremental visual wedges (pie slices).
• Each step exposes a few feet of the room while keeping the officer behind exterior wall cover. By the time the officer reaches the doorframe, 80% or more of the room has been visually cleared without stepping inside the fatal funnel.

Quick Peek Technique

• A rapid, momentary glance around a corner or doorway to gather visual information on uncleared sectors.
• Rules: The peek must be fast (fraction of a second); the officer must never peek from the same height twice in succession (e.g., peek high once, peek low near the knee the second time) to prevent an armed suspect from pre-aiming at the officer's head.

Entry Methods: Buttonhook vs. Criss-Cross

When entry is required, two-officer teams enter aggressively and immediately clear the "unseen" deep corners:

• Buttonhook Entry: Each officer enters the doorway and immediately wraps around the doorframe along their respective side of the entry wall, dominating the near corner.
• Criss-Cross Entry: Officers cross through the threshold from opposite sides, each traveling diagonally to clear the opposing corner.

Light Discipline & Flashlight Tactics

• Avoid backlighting or silhouetting a partner by shining lights from behind them.
• Intermittent Light Usage: Flashlights should not remain continuously illuminated during searches. Use short, sudden bursts of light ("flash and move") to illuminate an area, assess threats, and immediately displace to prevent the suspect from targeting the light source.
• Techniques: Use the Harries Technique (back of flashlight hand pressed against back of weapon hand for stability) or FBI Technique (holding light high and extended away from the body so rounds fired at the light miss the officer's torso).

7. The Contact and Cover Officer Operational Doctrine

Developed by the San Diego Police Department to eliminate officer deaths resulting from divided attention and tactical complacency, the Contact and Cover doctrine is the universal tactical operating system for two-officer interactions across Arizona.

                         [ Contact and Cover Triangulation ]
                         
                                   [ SUSPECT ]
                                      /   \
                                     /     \
                                    /       \
                                   /         \
                        [ CONTACT OFFICER ]   [ COVER OFFICER ]
                        Conducts interview;   Dedicated security;
                        searches, cuffs,      lethal cover, 360-degree scan;
                        handles paperwork     NO multitasking

Separation of Responsibilities

The fundamental premise of the doctrine is absolute role segregation: one officer handles the investigation and administrative mechanics, while the other provides dedicated tactical security.

| Operational Function | Contact Officer Responsibility | Cover Officer Responsibility | |:---|:---|:---|:---| | Primary Mission | Conducts all investigative and administrative tasks. | Provides continuous, dedicated lethal protection and security. | | Communication | Conducts all verbal dialogue with suspects, victims, and witnesses; handles all radio broadcasts. | Maintains complete radio and verbal silence; does not engage in casual conversation with suspects. | | Searching & Handcuffing | Performs all physical pat-downs, custodial searches, and applies handcuffs. | Maintains standoff distance; weapon staged/ready; observes suspect hands and furtive movements. | | Field Notes & Citations | Writes all field notes, checks identification, runs warrants on MDC, issues citations. | NEVER divides attention by looking at notepads, mobile computers, or paperwork. | | Environmental Awareness | Focused primarily on the subject and the immediate task. | Maintains continuous 360-degree scan of the surrounding area to detect approaching hostile third parties. |

Triangulation and Crossfire Avoidance

• The Contact and Cover officers must form a tactical triangle (L-shape) with the suspect at the apex.
• Officers must never stand directly opposite each other (a 180-degree line). If an officer stands opposite their partner, any rounds fired at a hostile suspect will pass directly into the partner's position.
• The Cover Officer positions themselves approximately 8 to 12 feet away from the suspect, maintaining an unobstructed field of fire and an angle that prevents the suspect from assaulting both officers simultaneously.

Role Switching and Non-Verbal Coordination

• Roles are established before exiting the vehicle or via clear verbal designation upon arrival.
• Roles should only switch if tactically necessary (e.g., the Contact Officer must physically struggle with a resisting suspect, requiring the Cover Officer to transition into a physical control role, or if specialized language skills dictate a switch).
• Officers use non-verbal cues (eye contact, head nods, tactical hand signals) to communicate weapon readiness or repositioning without alerting the suspect.

8. Exam Traps & Real-World Application Scenario

High-Yield Exam Traps for Section 6.2

1. The Multitasking Cover Officer Trap: A recurring exam scenario features a Cover Officer who begins writing notes, searching a vehicle, or looking at a computer during a contact. This is a critical tactical failure. The Cover Officer must never multitask or divide attention from security.
2. Sirens to the Scene: Driving with red lights and sirens directly up to the front entrance of an in-progress robbery violates invisible deployment and eliminates the element of surprise.
3. Cover vs. Concealment: Sheet metal car doors and interior drywall are concealment, NOT cover. The vehicle engine block and front wheel assemblies provide cover.
4. Diagonal Corner Containment: Two officers establish complete 360-degree exterior containment of a four-sided building by deploying at opposing diagonal corners (Corners 1 and 3).
5. Slicing the Pie Definition: Slicing the pie is an angular search method conducted from behind exterior cover before crossing the threshold, NOT a rapid entry into the room.

Operational Application Scenario

Scenario: Officers Evans and Brooks respond to a silent commercial burglary alarm at a pharmacy in Mesa, Arizona at 0300 hours. Officer Evans announces over the radio that they will approach from the south while a backup unit stages to the north. Two blocks prior to arrival, Evans turns off the siren and overhead lights, dims the MDC screen, and cuts headlights as they turn onto the business access lane.

Evans parks the marked cruiser two storefronts south of the pharmacy, positioning the vehicle with the front engine block angled toward the business. Both officers exit without slamming doors. Approaching on foot, they discover pry marks on the rear service door. Rather than rushing through the broken doorway (the fatal funnel), Evans and Brooks hold their position, establish diagonal corner containment with the arriving backup unit, and wait for a canine unit. Evans designates herself as the Contact Officer to handle radio coordination, while Brooks assumes Cover Officer duties, positioning in an L-shaped angle with a dedicated lethal weapon staged, scanning the perimeter without writing notes or looking at his phone.
