  • Effective Date: 01-01-2026
  • Revision Type: PRH Implementation, Terms Update
  • See other versions

Purpose

The purpose of this policy is to ensure that members who carry weapons and force devices, and who use weapons and force devices, including impact projectiles and launchers, adhere to the force guiding principles described in P&P 5-301. The force guiding principles include, but are not limited to, the Sanctity of Life (as incorporated below), the Duty to De-escalate, and Objectively Reasonable, Necessary, and Proportional Force.

MPD and its members shall uphold the sanctity of life (P&P 0-102 and P&P 5-301) by striving to protect and preserve human life in all situations and keep the community and MPD members safe from harm.

This policy addresses impact projectile use. Chemical munitions are covered by P&P 5-313.

Policy

Impact Projectiles as an Intermediate Weapon

Impact projectiles are generally considered an intermediate weapon when delivered to areas of the person’s body that are considered unlikely to cause death or serious physical injury. Depending on how members use the projectiles, including factors such as distance from the person, vulnerability of the person, and the area of impact on the person’s body, impact projectiles could result in great bodily harm or death.

Civil Disturbances and Assemblies

  1. All carrying and use of 40mm launchers and impact projectiles for crowd control purposes or during civil disturbances and assemblies shall only occur in accordance with P&P 7-805.
  1. Bean bag shotguns and bean bag rounds shall not be carried or used for crowd control purposes.

Pointing an Impact Projectile Launcher

  1. Members shall only point an impact projectile launcher at a person when there is an objectively reasonable belief that the use of impact projectiles may be necessary in the situation, as outlined in [II-D] and [II-E] below.
  1. Unnecessarily pointing an impact projectile launcher may limit a member’s alternatives in controlling a situation and may inhibit or limit communication between the member and the person.

Conditions for Use on a Person

Impact projectiles may only be used on a person in accordance with the factors and requirements described below. In addition to the conditions in this policy, the use of impact projectiles must be objectively reasonable, necessary, and proportional, and members shall use the lowest degree of force necessary (P&P 5-301). When using impact projectiles members must apply the critical decision-making model (CDM) (P&P 7-801) to continually assess the situation and modulate their use accordingly as the subject behavior changes.

Subject factors

Members shall only discharge impact projectiles at a person when:

  1. Such force is necessary to protect the member, the person, or another party from objectively imminent substantial bodily harm or greater.

or

  1. Both of the following apply:
  1. The member has reasonable suspicion to believe the person has committed one of the following offenses:
  • Sexual assault involving the use or threatened use of a dangerous weapon.
  • Homicide.
  • 1st and 2nd degree assault.
  • Aggravated robbery.
  • Kidnapping.
  • Firearms- felony firearm discharges, firearm pointing in violation of MN Statute section 609.66 Dangerous Weapons.

and

  1. Such force is necessary to place the person into custody or take control of the situation. Force may only be considered necessary when no reasonably effective alternative exists, meaning lower degrees of force or alternatives to force did not work, would not work, were not feasible or were too unsafe to attempt (P&P 5-301).

or

  1. A SWAT supervisor approves use by a member working in a SWAT capacity to provide a tactical advantage, in order to place the person into custody or take control of the situation, and no reasonably effective alternative exists meaning lower degrees of force or alternatives to force did not work, would not work, were not feasible or were too unsafe to attempt. This does not apply to the use of impact projectiles for crowd control purposes or during civil disturbances and assemblies (which shall only occur in accordance with P&P 7-805).

Consider vulnerable people

Members must consider the possible heightened risk of injury and adverse societal reaction to the use of impact projectiles upon certain people.

  1. Except where deadly force is the only other option, members shall not discharge impact projectiles at a person when a reasonable officer would know that the person is:
  • Pregnant.
  • Elderly.
  • A small minor.
  • A visibly frail person.
  1. Members must be able to articulate a correspondingly heightened justification when they discharge impact projectiles at a person when a reasonable officer would know the person is:
  • Any minor (under the age of 18).
  • A person in crisis (P&P 7-803).

Target areas

  1. The primary target areas for impact projectiles should be the large muscle groups in the lower extremities including the buttocks, thigh, and knees. Alternative target areas include the abdominal area to the waist.
  1. Members shall be aware that the delivery of impact projectiles to certain parts of the human body can cause grievous injury that can lead to a permanent physical or mental incapacity or possible death.This could include loss of vision, damage to organs, skull fractures, brain injury, etc.
  2. Members shall not intentionally discharge impact projectiles at a person’s head, neck, throat, face, chest, armpit, spine, or groin unless deadly force would be authorized.

Consider risks and other means of control

Prior to discharging impact projectiles at a person, members shall consider:

  1. Any risks to the public or to the members.
  2. Whether the person could be controlled by any other reasonable means without unnecessary risk to the person, members, or to the public.

Separate uses of force

Each impact projectile discharge at a person is a separate use of force that members must separately justify as objectively reasonable, necessary, and proportional.

Conditions for Use on a Surface

Impact projectiles may only be used on a surface in accordance with the factors and requirements described below. In addition to the conditions in this policy, the use of impact projectiles must be objectively reasonable, necessary, and proportional, and members are reminded that they shall use the lowest degree of force necessary (P&P 5-301). When using impact projectiles members must apply the Critical Decision-Making Model (CDM) (P&P 7-801) to continually assess the situation and modulate their use accordingly as the subject behavior change.

Authorization

Members shall only discharge impact projectiles at a surface such as a window, structure or stationary vehicle in one of the following situations:

  1. For life-saving purposes.
  1. When approved by the Chief or the Chief’s designee.
  2. When an occupant of a vehicle who is reasonably believed to be armed with a firearm refuses to exit the vehicle following a lawful command to do so, a SWAT supervisor can approve the use of impact projectiles on the vehicle.
  3. As a means to breach a structure and communicate with the occupants or introduce technology such as unmanned aerial systems (P&P 4-226) or reconnaissance robots into the structure, and such use of the impact projectiles is approved by a SWAT supervisor. Deployment in this situation is intended to allow for de-escalation tactics such as establishing new lines of communication or observation.
  4. To break a window to allow for delivery of chemical munitions, when the chemical munition use has been authorized in accordance with P&P 5-313.

Method of use

When using an impact projectile on a surface, the impact projectile may only be used in one of these ways:

  1. Directed away from the person’s location as a distraction.

or

  1. Used to breach a window.

Consider risks

Prior to using impact projectiles on a surface, members need to consider the risks to any person who may be struck by the projectile or by debris caused by the projectile’s impact on the surface.

Announcements

It is important that whenever possible, all members involved, and possible responding members, know that an impact projectile is being discharged so they do not mistake the sight and noise from the impact projectile discharge as a live ammunition discharge. In addition to the requirements in “Identify Self and Warn of Intent” in P&P 5-301:

  1. Members shall announce over the radio that an impact projectile will be discharged, when time and tactics permit.
  1. Whenever feasible, members who discharge impact projectiles should yell "Code Orange!" prior to and during the discharge.

Note: Impact projectile launchers have an orange barrel indicating they are intermediate weapons (see the specifications in section [M]).

Requesting a 40mm Operator

If a supervisor or responding member believes that there is a call or incident that may require 40mm capability, they may request via radio or other means that an on-duty MPD-trained operator with a 40mm launcher respond to the scene.

Carrying, Storage and Tracking of 40mm Launchers

  1. 40mm launchers shall be assigned to each precinct, City Hall and specialty units as needed. Only certified operators are authorized to carry 40mm launchers.
  1. Each 40mm launcher shall be kept its own case and in a secured gun locker.
  2. All 40mm rounds stored at the precincts shall be checked out by a supervisor, except in emergency circumstances. Operators shall check their unused 40mm rounds back in with a supervisor at the end of their shift. The Operator and a Supervisor shall sign the rounds out and back in using the 40mm Sign-Out Sheet.
  3. Patrol supervisors shall assign at least one 40mm launcher to a certified operator at the start of the shift (if the shift has an operator who is current with their certification).
  4. MPD-trained operators shall have the 40mm launchers available during their assigned shift, when possible.

Collecting Spent Projectiles

Supervisors and operators shall ensure that all spent impact projectiles are collected and property inventoried if possible (P&P 10-400).

Maintenance of Impact Projectile Launchers

Only MPD certified Range personnel and trained SWAT personnel shall perform maintenance and repairs to the 40mm launcher and bean bag shotgun.

Treatment and Medical Aid

In addition to standard medical treatment after uses of force (in accordance with P&P 5-301 and P&P 7-350), when a person is struck by an impact projectile, treatment for the person shall include visually inspecting the areas struck for signs of injury, when appropriate. Members shall keep the person under close observation until they are released to medical or other law enforcement personnel.

Training Required

  1. Only members who have completed the required training in the use of the 40mm launcher and 40mm rounds are authorized to carry and use them.
  1. Only members who have completed the required training in the use of bean bag rounds and bean bag shotguns are authorized to carry and use them.

  • Subject Behavior:
    Subject Behavior: The actions, language, demeanor and conduct exhibited by a person. The behaviors are used to categorize and assess the degree of cooperation, resistance, or threat posed by the person.
    Complying with Orders: The person is following direction or lawful orders given.
    Passively Resisting: The person is not complying with a member’s commands and is uncooperative but is taking only minimal action to prevent a member from placing the person in custody or taking control of the situation. Examples include:
    • Standing stationary and not moving upon lawful direction.
    • Falling limply and refusing to use their power to move (becoming "dead weight").

      • Use of a firearm.
      • Use of a blunt or bladed weapon.
      • Extreme physical force.
  • Unmanned Aerial System: An unmanned aircraft of any type that is capable of sustaining directed flight, whether preprogrammed or remotely controlled without the possibility of direct human intervention from within or on the aircraft (UAV), and all of the supporting or attached systems designed for gathering information through imaging, recording, or any other means.
  • Use of Force:

    An intentional contact, directly or indirectly (such as through a weapon or force device), with someone’s body, that causes pain or injury or restricts, controls or directs someone’s movement. Intentionally placing someone in fear of such contact or threatening such contact can also constitute force. This includes, but is not limited to:

    • The use of any weapon, substance, vehicle, equipment, tool, device or animal that inflicts pain or produces injury.
    • Any physical strike to any part of the body.
    • Any physical contact or threat of contact by the member or a weapon that causes or threatens to cause pain or injury.
    • Any physical contact or threat of physical contact by the member that results in physical restriction or manipulation of movement.
    • Unholstering or displaying a weapon when engaged with a subject or subjects, or pointing a weapon at a person.
  • Use Weapons and Force Devices: Activating or applying a weapon's or force device's mechanical functions, pointing a weapon, or making contact with a person with the weapon or force device. This includes discharging a weapon such as a firearm, chemical aerosol, or impact projectile launcher, deploying a CEW, performing a CEW warning alert, activating a CEW, laser painting a person, applying handcuffs or restraints, and making bodily contact with a person with a baton or other impact weapon.
