Federal agents have frequently used so-called âless-lethalâ weapons against protesters, including impact projectiles, tear gas and pepper spray, since the Trump administrationâs nationwide immigration raids began last year.
The use of less-lethal weapons (LLWs) has been controversial. While designed to incapacitate or control a person without causing death or permanent injury, they can cause serious or fatal injuries, especially when used improperly.
Earlier this month, two protesters in California were reportedly blinded after US federal agents fired less-lethal rounds at their faces from close range. These incidents were part of a wave of violent clashes between agents from the Department of Homeland Security (DHS) and protesters across the country after the deadly shooting of US citizen Renee Good by an Immigration and Customs Enforcement (ICE) agent in Minneapolis.

In protests in Minneapolis immediately following Goodâs death, one Customs and Border Patrol (CBP) officer was captured on camera firing a 40mm less-lethal launcher five times in less than five minutes, with several of these shots appearing to target protestersâ faces, which is against CBPâs own use-of-force policy.
A Bellingcat investigation of DHS incidents in October 2025 also found about 30 incidents that appeared to violate a temporary restraining order (TRO) issued by an Illinois judge restricting how DHS agents could use LLWs.

It is not always obvious whether the use of a LLW is authorised or not, as DHS component agencies such as ICE and CBP have varying guidance on factors such as the level of resistance an individual needs to show before a certain type of force can be used, as well as how specific types of less-lethal weapons and munitions can be used.
While CBPâs use-of-force policy as of January 2021 is available on its website, ICE does not include specific guidance on less-lethal weapons in its 2023 âFirearms and Use of Forceâ Directive, and does not appear to have any publicly available policy that outlines this guidance.
DHS did not respond by publication time to Bellingcatâs request for the most recent DHS, CBP and ICE use-of-force policies, or to questions about what less-lethal weapons were authorised for use by the department and its component agencies.
The DHS use-of-force policy, updated in February 2023, states that the departmentâs law enforcement officers and agents may use force, including LLWs, âonly when no reasonably effective, safe and feasible alternative appears to existâ. It also says agents may only use a level of force that is âobjectively reasonable in light of the facts and circumstancesâ that they face at the time.
DHS has repeatedly defended its use of riot-control weapons in protests across the country, stating that it was âtaking reasonable and constitutional measures to uphold the rule of law and protect [its] officersâ.
Hereâs how to identify some of the less-lethal weapons that DHS agents, including those from ICE and CBP, have been seen using during recent immigration operations.
Compressed Air Launchers or âPepperBall Gunsâ

Compressed air, or pneumatic launchers, are essentially paintball guns that fire 0.68mm balls which break on impact. Often, this releases a powdered chemical irritant such as oleoresin capsicum (OC) or PavaPowder â the same compounds typically found in pepper spray.
Compressed air launchers can also be used with other projectiles, such as âmarkingâ projectiles that use paint to mark an individual for later arrest, and projectiles intended to break glass.
These weapons are often referred to as âPepperBallâ guns, named after the leading brand PepperBall. However, DHS agents have also been seen carrying compressed air launchers from different brands, such as the FN303, produced by FN America.
Many compressed air launchers resemble standard paintball guns, with a distinct hopper or loader, which holds the ball projectiles, mounted to the top. They also have a compressed air tank that might be mounted to the side, bottom, or inside the buttstock (or back) of the weapon.
Many compressed air launchers, and less-lethal weapons in general, have very bright colours such as orange to distinguish them from lethal weapons.



However, some compressed air launchers require closer scrutiny to distinguish them from firearms.
For example, federal agents have been seen carrying FN303 compressed air launchers in videos of immigration enforcement activities. This weapon may resemble a rifle or other firearm, as it is usually all-black and, unlike the TAC-SF series PepperBall guns, lacks a visible hopper.

If closer examination is possible, this weapon can be identified by its distinct features, including a circular magazine, side-mounted compressed air tank and a hose connecting the firearm to the air tank.

The January 2021 CBP Use of Force Policy places several restrictions on the use of compressed air launchers, including that they should not be used against small children, the elderly, visibly pregnant women, or people operating a vehicle. It also states that PepperBall guns should not be used within 3 feet âunless the use of deadly force is reasonable and necessaryâ. When using the FN303, the minimum distance is increased to 10 feet.
The CBP Use of Force Policy says that the intentional targeting of areas where there is a âsubstantial risk of serious bodily injury or death is considered a use of deadly force.â Agents are instructed not to target âthe head, neck, spine, or groin of the intended subject, unless the use of deadly force is reasonableâ. PepperBall and FN America provide similar warnings about avoiding vital areas to prevent serious injury or death.
According to a 2021 report by the US Office of Inspector General, CBP requires its agents to recertify their training to use PepperBall guns and FN303s every year, but ICE does not.
40mm Launchers

DHS agents also use 40mm launchers to fire âLess-Lethal Specialist Impact and Chemical Munitions (LLSI-CM)â. These launchers resemble military grenade launchers, but are used to fire less-lethal ammunition, including âspongeâ rounds that can disperse chemical irritants on impact.
Federal agents have been seen using or carrying the B&T GL06 launcher in footage of multiple incidents reviewed by Bellingcat. They have also been spotted with other 40mm launchers, including Penn Arms 40mm multi-shot launchers, which have a six-round cylinder magazine.

There are various less-lethal munitions available for 40mm launchers, including those whose primary function is âpain complianceâ through the force of impact, chemical irritants or a combination of both.
Videos of clashes between Border Patrol agents and protesters show these launchers being used with combination rounds designed to hit the target for pain compliance while also delivering a chemical irritant such as OC or CS.

Other munitions dispense chemical irritants or smoke after being launched. For example, in the protests immediately following Goodâs death, a Border Patrol agent was seen firing a 40mm munition that released multiple projectiles emitting chemical irritants in a single shot, consistent with the âSKAT Shellâ by Defense Technology.

Defense Technologyâs technical specifications for its 40mm Direct Impact Rounds, which agents have been seen armed with, state that the munitions are considered less-lethal when fired at a minimum safe range of 5 feet and at the large muscle groups of the buttocks, thigh and knees, which âprovide sufficient pain stimulus, while greatly reducing serious or life-threatening injuriesâ.
A DHS Office of Inspector General Report in 2021 noted varying guidance on the use of 40mm launchers among the departmentâs component agencies: âICEâs use of force policy indicates that the 40MM launcher is deadly force when fired at someone, while the CBP use of force policy only directs officers not to target a personâs head or neck.â
CBPâs 2021 use-of-force policy states that agents should ânot intentionally target the head, neck, groin, spine, or female breastâ, and that anyone in custody who has been subject to such munitions should be seen by a medical professional âas soon as practicableâ.
As of publication, DHS had not replied to Bellingcatâs questions about whether the department had an internal policy or provided training to staff on the minimum safe distance for 40mm less-lethal launchers as recommended by the manufacturers.
Hand-Thrown Munitions

DHS agents have also been seen throwing some less-lethal munitions, such as flash-bangs, smoke and âtear gasâ grenades or canisters by hand.
These munitions activate a short delay after the grenade is employed. When they activate, flash-bangs or âstunâ grenades emit a bright flash of light and a loud sound that is designed to disorient targets. Both smoke grenades and tear gas (also known as âCS gasâ or âOC gasâ) emit thick smoke, but the former just impedes visibility, whereas the latter also contains chemical irritants that sting the eyes.
Defense Technology offers smoke grenades with hexachloroethane smoke composition, but most of their smoke grenades use âSAF-Smokeâ, a less toxic terephthalic acid smoke composition.
Hexachloroethane, while toxic, is not a nerve agent, despite misinformation surrounding the deployment of green colored smoke grenades in Minnesota by DHS personnel.
The shape and general construction, colour, and any text can help identify these munitions.
Less-lethal munitions typically feature the manufacturerâs logo, the model name of the munition, and the model or part number. The text and manufacturer logo are typically colour-coded to indicate the type of payload the munition has, with blue indicating CS, orange indicating OC, yellow indicating smoke, green indicating a marking composition and black indicating munitions with no chemical payload.

A 2021 analysis by Bellingcat and Newsy found that Defense Technology and Combined Tactical Systems, the two manufacturers which produce most of the less-lethal munitions used by federal agents, both list the model numbers of their products online. Publicly available price lists for Defense Technology and Combined Tactical Systems can also be used to identify specific munitions by their model numbers.

CBPâs 2021 use-of-force policy states that hand-thrown munitions are subject to the same restrictions for use as munition launcher-fired impact and chemical munitions.
Chemical Irritant Sprays

DHS agents have also been using handheld chemical irritant sprays, often colloquially referred to as âpepper sprayâ or âmaceâ.
These sprays come in a variety of sizes and concentrations containing CS, OC, or both. Sprays used by law enforcement usually have a canister size designated âMK-â followed by a number, with higher numbers indicating larger canister sizes. The concentration of chemical irritants contained in the spray is also indicated on the canister.

The effectiveness of OC sprays is determined by the concentration of major capsaicinoids, which are the active compounds in OC that cause irritation. These sprays are also affected by the type of aerosol dispersion, or stream, used. Different types of streams increase or decrease the range of the spray as well as the coverage area.
Civilian and law enforcement sprays range from 0.18 percent to 1.33 percent major capsaicinoids, according to SABRE, a producer of law enforcement and civilian sprays. Civilian sprays in the US can have the same major capsaicinoid content as law enforcement sprays, but are restricted to smaller-sized canisters.

Defense Technology sprays have different colour bands to indicate the percentage of major capsaicinoids in the spray for OC. If the spray is CS, the CS concentration is standardised at 2 percent. The company uses a white band for .2 percent, yellow band for .4 percent, orange band for .7 percent, red band for 1.3 percent and a grey band for sprays containing either CS or a combination of OC and CS.
SABRE sells a variety of concentrations and sprays as law enforcement products, including 0.33 percent, 0.67 percent, and 1.33 percent major capsaicinoid concentrations of OC, as well as CS, and combination CS and OC sprays. The specific concentrations of SABRE sprays and the type of stream can also be identified by the text on the canister.
One Air Force Research Laboratory study found that some sprays may pose a significant risk of severe eye damage due to pressure injuries resulting from large aerosol droplets hitting the eye.
Defense Technologyâs technical specifications recommend a minimum distance of between 3 and 6 feet, depending on the specific spray. SABRE does not publicly provide their minimum safe deployment distances, but a Mesa Police Department document lists a minimum distance of six feet for the SABRE Red MK-9. CBPâs 2021 use-of-force policy does not provide any minimum use distances.
CBPâs 2021 use-of-force policy states that OC Spray may only be used on individuals offering âactive resistanceâ, and that it should not be used on âsmall children; visibly pregnant; and operators of motor vehiclesâ.
Electronic Control Weapons

DHS agents have also been seen using electronic control weapons (ECWs), which are colloquially called TASERs after the original weapon invented for law enforcement use, in immigration-related raids.
ECWs can deliver a shock upon direct contact or launch probes that embed in the targeted person, incapacitating them.
A shock on contact, or a âdrive-stunâ feature, delivers localised pain while in direct contact. When properly deployed, the probes send signals to the body that cause muscles to contract. A personâs body âlocking upâ from muscle contractions is an indicator that an ECW has been deployed. ECWs may be capable of using either or both methods.
ECWs are typically painted a combination of black and bright yellow, but this varies between models. The bright colour of parts of tasers is a common feature to help distinguish an ECW from handguns used by federal agents. When viewed from the front, a circular gun barrel is visible on handguns, while ECWs feature multiple circular probes or rectangular covers on the cartridge. ECWs also usually have flashlights and lasers, although handguns may also be equipped with these features. Some ECWs may make audible sounds when armed or deployed.

Axon, the predominant manufacturer of ECWs, produces several models including the TASER 10 and TASER 7. Axon provides a policy guide on recommended use of its TASER models to law enforcement agencies, which recommends targeting below the neck from behind, or the lower torso from the front. It recommends avoiding sensitive areas including the head, face, throat, chest and groin.
Axon also recommends against using ECWs against small children, the elderly, pregnant people, very thin people and individuals in positions of increased risks such as running, operating a motor vehicle, or in an elevated position âunless the situation justifies an increased riskâ.
CBPâs 2021 use-of-force policy, in addition to restricting the use of ECWs against small children, the elderly, visibly pregnant women, and people operating a vehicle, states that they should not be used against someone who is running or handcuffed. However, the policy does state that there may be an exception to the rule against using ECWs on a running person if an agent has a âreasonable belief that the subject presents an imminent threat of injuryâ to an agent or another person. This threat, according to the policy, must âoutweigh the risk of injury to the subject that might occur as a result of an uncontrolled fall while the subject is runningâ.
