The **United States Border Patrol** (USBP) is a federal law enforcement agency under the United States Customs and Border Protection (CBP) and is responsible for securing the borders of the United States. According to its web site in 2022, its mission is to "Protect the American people, safeguard our borders, and enhance the nation’s economic prosperity."

With 19,648 agents in 2019, the Border Patrol is one of the largest law enforcement agencies in the United States. For fiscal year 2017, Congress enacted a budget of $3,805,253,000 for the Border Patrol. The Border Patrol has the lowest proportion of female agents or officers of any federal agency.

There have been complaints, over many years, of Border Patrol agents mistreating migrants and exceeding their legal authority.

## History

In the nineteenth century, United States borders were open and unrestricted; there was no systematic control or even recordkeeping of immigrants. The first legislation restricting immigration, after the Act Prohibiting Importation of Slaves of 1807, was the Chinese Exclusion Act of 1882.

Mounted watchmen of the United States Department of Commerce and Labor patrolled the border in an effort to prevent illegal crossings as early as 1904, but their efforts were irregular and undertaken only when resources permitted. The inspectors, usually called "mounted guards", operated out of El Paso, Texas. Though they never totaled more than 75, they patrolled as far west as California trying to restrict the flow of illegal Chinese immigration.

In March 1915, Congress authorized a separate group of mounted guards, often referred to as "mounted inspectors". Most rode on horseback, but a few operated automobiles, motorcycles, and boats. Although these inspectors had broader arrest authority, they still largely pursued Chinese aliens trying to avoid the National Origins Act and Chinese Exclusion Act of 1882. These patrolmen were immigration inspectors, assigned to inspection stations, and could not watch the border at all times. U.S. Army soldiers along the southwest border performed intermittent border patrolling, but this was secondary to "the more serious work of military training". Aliens encountered illegally in the U.S. by the Army were directed to the immigration inspection stations. Texas Rangers were also sporadically assigned to patrol duties by the state, and their efforts were noted as "singularly effective".

The National Origins Act authorized the formation of the U.S. Border Patrol on May 26, 1924. Two days later, the *Labor Appropriation Act of 1924* established the Border Patrol as an agency of the U.S. Department of Laborassigned to prevent illegal entries—primarily along the Mexico–United States border, as well as the Canada–U.S. border. The first Border Patrol station began operations in Detroit, Michigan, in June 1924. A second station, in El Paso, Texas, began operations in July 1924. In 1925, coastal patrols began as well. Operations were established along the Gulf Coast in 1927 to ensure that foreign crewmen departed on the same ship on which they arrived. In 1932, the Border Patrol was divided into two offices. Mexican border operations were directed from El Paso, Texas, and Canadian border operations were directed from Detroit, Michigan. The Canadian border operations from Detroit employed more men than the El Paso operations along the Mexican border because of a focus on the prevention of liquor smuggling during prohibition. Franklin Delano Roosevelt's Executive Order 6166 formed the Immigration and Naturalization Service (INS) in 1933 by consolidation of the Bureau of Immigration and the Bureau of Naturalization. Following the outbreak of World War II in Europe, Border Patrol staffing doubled to 1,500 in 1940, and the INS was moved from the Department of Labor to the U.S. Department of Justice. Additional stations were temporarily added along the Gulf Coast, Florida and the Eastern Seaboard during the 1960s after Fidel Castro triumphed in the Cuban Revolution, and that was followed by the Cuban Missile Crisis. The INS was decommissioned in March 2003 when its operations were divided between U.S. Customs and Border Protection (CBP), United States Citizenship and Immigration Services, and U.S. Immigration and Customs Enforcement.

In the wake of the attacks of September 11, 2001, the Border Patrol was placed under the umbrella of the Department of Homeland Security, and preventing terrorists and terrorist weapons from entering the United States was added to its mission. The Border Patrol's traditional mission continued: deterring, detecting and apprehending illegal aliens and individuals involved in the illegal drug trade who generally entered the United States at places other than through designated ports of entry. The Border Patrol also erected 33 permanent interior checkpoints near the southern border of the United States.

For fiscal year 2019, the nationwide total of Border Patrol agents was 19,648, with 16,731 patrolling the southern border. Agents primarily patrol the Mexico–United States border, where they control drug trafficking and illegal immigration.

The majority of Border Patrol agents are minorities. According to 2016 data, Latinos constitute slightly more than 50% of the Border Patrol.

In late 2021, after public criticism, the Border Patrol outfitted agents with body cameras, which it had rejected in 2015 as too expensive, bad for agent morale, and unreliable; it had previously required state and local law enforcement to turn off their body cameras during joint operations with CBP.

In September 2021, while mounted Border Patrol agents in Del Rio, Texas, responded to an influx of refugees from Haiti crossing the Mexico–United States border, a photograph was captured of an agent appearing to use his bridle reins as a whip against a Haitian migrant. U.S. President Joe Biden said, "To see people treated like they did, horses barely running over, people being strapped. It's outrageous. I promise you those people will pay. There will be an investigation underway now, and there will be consequences. There will be consequences." The photographer, when interviewed, said he did not see any whipping. Months later, in November 2021, The Department of Homeland Security's Office of Inspector General (OIG) declined to investigate allegations against the agents on horseback.

## Strategy

### 1986: Employer sanctions and interior enforcement

The Border Patrol's priorities have changed over the years. In 1986, the Immigration Reform and Control Act placed renewed emphasis on controlling illegal immigration by going after the employers that hire illegal aliens. The belief was that jobs were the magnet that attracted most illegal aliens to come to the United States. The Border Patrol increased interior enforcement and Form I-9 audits of businesses through an inspection program known as "employer sanctions". Several agents were assigned to interior stations, such as within the Livermore Sector in Northern California.

Employer sanctions never became the effective tool it was expected to be by Congress. Illegal immigration continued to swell after the 1986 amnesty despite employer sanctions. By 1993, Californians passed Proposition 187, denying benefits to illegal aliens and criminalizing illegal aliens in possession of forged green cards, identification cards, and Social Security numbers. It also authorized police officers to question non-nationals as to their immigration status and required police and sheriff departments to cooperate and report illegal aliens to the INS. Proposition 187 drew nationwide attention to illegal immigration.

#### Checkpoint stations

United States Border Patrol Interior Checkpoints are inspection stations operated by the USBP within 100 miles (160 km) of an international border (with Mexico or Canada) or any U.S. coastline.

#### El Paso Sector's Operation Hold the Line

El Paso Sector Chief Patrol Agent Silvestre Reyes started a program called "Operation Hold the Line". In this program, Border Patrol agents would no longer react to illegal entries resulting in apprehensions, but would instead be forward deployed to the border, immediately detecting any attempted entries or deterring crossing at a more remote location. The idea was that it would be easier to capture illegal entrants in the wide open deserts than through the urban alleyways. Chief Reyes deployed his agents along the Rio Grande, within eyesight of other agents. The program significantly reduced illegal entries in the urban part of El Paso by shifting them to other areas.

#### San Diego sector's Operation Gatekeeper

Congressman Duncan Hunter became a major proponent of additional border fencing in the San Diego sector; surplus military landing mats were obtained to use as an initial border fence. Stadium lighting, ground sensors and infra-red cameras were also placed in the area. Eventually the primitive landing mat fence was replaced with a modern triple fence line that begins over one hundred yards into the Pacific Ocean at Imperial Beach, California, and ends more than 13 miles (19 km) inland on Otay Mesa where the mountains begin.

#### Northern border

Through agency whistleblowers, Agent Mark Hall and Agent Robert Lindemann, it was revealed that in 2001, the Border Patrol had approximately 324 agents assigned along the Canada–United States border. Northern border staffing had been increased by 1,128 agents to 1,470 agents by the end of fiscal year 2008, and is projected to expand to 1,845 by the end of fiscal year 2009, a six-fold increase. Resources that support Border Patrol agents include the use of new technology and a more focused application of air and marine assets.

The northern border sectors are (west to east): Blaine (Washington), Spokane (Washington), Havre (Montana), Grand Forks (North Dakota), Detroit (Selfridge ANGB, Michigan), Buffalo (New York), Swanton (Vermont), and Houlton (Maine).

### New strategy

In November 2005, the U.S. Border Patrol published an updated national strategy. The goal of this updated strategy was operational control of the United States border. The strategy has five main objectives:

* Apprehend terrorists and terrorist weapons illegally entering the United States
* Deter illegal entries through improved enforcement
* Detect, apprehend, and deter smugglers of humans, drugs, and other contraband
* Use "smart border" technology
* Reduce crime in border communities, improving quality of life.

## Capabilities

The United States border is a barely discernible line in the uninhabited deserts, canyons, or mountains and rivers. The Border Patrol utilizes a variety of equipment and methods, such as electronic sensors placed at strategic locations along the border, to detect people or vehicles entering the country illegally. Video monitors and night vision scopes are also used to detect illegal entries. Agents patrol the border in vehicles, boats, aircraft, and afoot. In some areas, the Border Patrol employs horses, all-terrain motorcycles, bicycles, and snowmobiles. Air surveillance capabilities are provided by unmanned aerial vehicles.

The primary activity of a Border Patrol agent is "line watch". Line watch involves the detection, prevention, and apprehension of terrorists, illegal aliens and smugglers of aliens at or near the land border by maintaining surveillance from a covert position; following up on leads; responding to electronic sensor, television systems and aircraft sightings; and interpreting and following tracks, marks, and other physical evidence. Major activities include traffic check, traffic observation, city patrol, transportation check, administrative, intelligence, and anti-smuggling activities.

Traffic checks are conducted on major highways leading away from the border to detect and apprehend illegal aliens attempting to travel further into the interior of the United States after evading detection at the border, and to detect illegal narcotics.

Transportation checks are inspections of interior-bound conveyances, which include buses, commercial aircraft, passenger and freight trains, and marine craft.

Marine patrols are conducted along the coastal waterways of the United States, primarily along the Pacific coast, the Caribbean, the tip of Florida, and Puerto Rico and interior waterways common to the United States and Canada. The Border Patrol conducts patrol activities from 130 marine craft of various sizes. The Border Patrol maintains watercraft ranging from blue-water craft to inflatable-hull craft, in 16 sectors, in addition to headquarters and special operations components. The Border Patrol Marine Position was created in 2009 (BPA-M).

Horse and bike patrols are used to augment regular vehicle and foot patrols. Horse units patrol remote areas along the international boundary that are inaccessible to standard all-terrain vehicles. Bike patrol aids city patrol and is used over rough terrain to support line watch. Snowmobiles are used to patrol remote areas along the northern border in the winter.

## Expansion

In 1992, the United States Border Patrol had approximately 4,139 patrol agents on the job. Attrition in the Border Patrol was normally at 5%. From 1995 to 2001 annual attrition rose to above 10%, which was a period when the Border Patrol was undergoing massive hiring. In 2002 the attrition rate climbed to 18%. The 18% attrition was largely attributed to agents transferring to the Federal Air Marshals after 9/11. In 2017, the attrition rate was at 6%.

The Intelligence Reform and Terrorism Prevention Act of 2004 (signed by President Bush on December 17, 2004) authorized hiring an additional 10,000 agents, "subject to appropriation". This authorization nearly doubled the Border Patrol size, from 11,000 to 20,000 agents by 2010. As of 2016, roughly half of the agents are Latino Americans.

The Secure Fence Act, signed by President Bush on October 26, 2006, has met with much opposition. In October 2007, environmental groups and concerned citizens filed a restraining order hoping to halt the construction of the fence, set to be built between the United States and Mexico. The act mandated that the fence be built by December 2008. Ultimately, the United States seeks to put fencing around the 1,945-mile (3,130 km) border, but the act requires only 700 miles (1,100 km) of fencing. DHS secretary Michael Chertoff has bypassed environmental and other oppositions with a waiver that was granted to him by Congress in Section 102 of the act, which allows DHS to avoid any conflicts that would prevent a speedy assembly of the fence.

This action has led many environment groups and landowners to speak out against the impending construction of the fence.Environment and wildlife groups fear that the plans to clear brush, construct fences, install bright lights, motion sensors, and cameras will scare wildlife and endanger the indigenous species of the area. Environmentalists claim that the ecosystem could be affected because a border fence would restrict movement of all animal species, which in turn would keep them from water and food sources on one side or another. Desert plants would also feel the impact, as they would be uprooted in many areas where the fence is set to occupy.

In 2008, property owners in these areas feared a loss of land. Landowners would have had to give some of their land over to the government for the fence. Brownsville mayor Pat Ahumada favored alternative options to a border fence. He suggested that the Rio Grande be widened and deepened to provide for a natural barrier to hinder illegal aliens and drug smugglers.

## Other specialized programs

In 2007, the U.S. Border Patrol created the special operations group (SOG) headquartered in El Paso, Texas, to coordinate the special operations units of the agency.

The U.S. Border Patrol has a number of other specialized programs and details. Marine patrol – In the riverine environments of the northern and southwestern borders of the continental United States, the Border Patrol conducts border control activities from the decks of marine craft of various sizes. Since 2006, the U.S. Border Patrol has relinquished its littoral law enforcement missions in the Great Lakes and territorial seas to the Office of Air and Marine. The U.S. Border Patrol maintains over 130 vessels, ranging from blue-water craft to inflatable-hull craft, in 16 sectors, in addition to headquarters special operations components.

K9 units, mounted patrols, bike patrols, sign-cutting (tracking), snowmobile units, infrared-scope units, intelligence, anti-smugglinginvestigations unit (ASU/DISRUPT, Border Criminal Alien Program, multi-agency anti-gang task forces (regional and local units), honor guards, pipes and drums, chaplains, peer support, and mobile surveillance units.

## Deterrence

"Operation Gatekeeper" was launched in 1994 to stop aliens from crossing illegally into the United States. The strategy included increased enforcement and extensive fencing near border cities, with the two-fold purpose of deflecting aliens to remote areas where they could more easily be detected and apprehended, as well as using mountains, deserts, and Rio Grande as a deterrent to easy passage. The newly erected Mexico–United States barrier—which at some remote locations is no more than a fence—has also forced aliens and human traffickers to seek out remote desert locations in California, Arizona, New Mexico and Texas where they may attempt crossing. The "funnel effect" created by both these strategies has contributed to the deaths of thousands of aliens, whose remains are often found in the hot desert or freezing mountains.

As early as 1998, the former Immigration and Naturalization Service implemented the Border Safety Initiative in response to concerns about the number of aliens injured or killed while attempting to cross the border. It was noted that Border Patrol agents routinely supplied water, food, and medical care to aliens. That same year, Border Patrol, Search, Trauma and Rescue (BORSTAR), a specialized unit trained in emergency search and rescue, was established with the purpose of assisting injured or stranded aliens at remote locations.

In 2002, the first "rescue beacons" were installed in desert areas considered especially dangerous. The beacons are solar powered and highly visible, and have a button which alerts Border Patrol agents by radio signal, after which a helicopter or ground unit is dispatched. U.S. Senator Bill Frist commented in 2006: "these beacons, I believe, are an absolutely vital link in our border security system... We know that beacons work: CBP has already saved dozens of people based entirely on beacon alerts." The Border Patrol frequently publishes reports about stranded and injured individuals rescued at beacon locations.

In fiscal year 2020, Border Patrol agents and Air and Marine Operations agents are credited with saving more than 5,000 people and conducted approximately 1,400 search and rescue operations.

## Training

All Border Patrol agents spend a minimum of 26 weeks at the Border Patrol Academy in Artesia, New Mexico, which is a component of the Federal Law Enforcement Training Centers (FLETC). Border Patrol Agent Trainees are instructed in courses including; Spanish, criminal law, nationality law, and administrative immigration law, police sciences, self-defense and arrest techniques, firearms training with pistol, shotgun and rifle, police vehicle driving, and other Border Patrol / federal law enforcement subjects.

Once they arrive back at their duty station, Trainees then must graduate from the Field Training program, an on-the-job training program led by a Field Training Officer (FTO), which varies in length from a minimum of 12 weeks to a maximum of over 16 weeks long, depending on the practical demands of the duty station and local management.

## Appearance

### Uniforms

The Border Patrol, around the year 2007, wore the following types of uniforms:

* Summer dress uniform – The summer dress uniform consists of a short-sleeve, olive-green dress shirt (which may or may not have blue shoulder straps), brass nameplate, badge, olive-green slacks with a blue stripe running the length of the seam, and black dress shoes or dress boots. A green, straw campaign hat is worn with this uniform.
* Winter dress uniform – The winter dress uniform consists of a long-sleeve, olive green dress shirt, navy-blue clip-on tie with a brass tie tack, olive-green ike jacket with blue accents (shoulder straps and cuffs), brass nameplate, badge, olive-green slacks with a blue stripe running the length of the seam, and black dress shoes or dress boots. A green, felt campaign hat with a black, leather hat band is worn with this uniform.
* Ceremonial dress uniform – Worn primarily by Border Patrol honor guard agents, the ceremonial dress uniform is roughly identical to the winter dress uniform, with the exception that a tunic is worn with this uniform, rather than an ike jacket. White, cloth gloves are also worn with this uniform.
* Rough duty uniform – The rough duty uniform consists of a green, long-sleeve or short-sleeve work shirt, green cargo pants, and black work boots; a green baseball cap or cowboy hat is typically worn with this uniform.
	+ There are also specialized rough duty uniforms for marine patrol (riverine), northern border cold weather, horse patrol and bike patrol agents.
* Highland uniform – Worn by members of the United States Border Patrol Pipes and Drums in the performance of their official duties, this uniform includes a kilt made of the official Border Patrol tartan, custom made olive-green ceremonial coat, glengarry, sporran and white spats.
* Organization patches – The Border Patrol wears two:
	+ The CBP patch is worn on the right sleeves of the uniform. It contains the DHS seal against a black background with a "keystone" shape. A keystone is the central, wedge-shaped stone in an arch, which holds all the other stones in place.
	+ Border Patrol agents retain the circular legacy Border Patrol patch, which is worn on the left sleeve.

The Border Patrol uniform got its first makeover since the 1950s to appear more like military fatigues and less like a police officer's duty garb. Leather belts with brass buckles have been replaced by nylon belts with quick-release plastic buckles, slacks have been replaced by lightweight cargo pants, and shiny badges and nameplates have been replaced by cloth patches.

## Equipment

### Weapons

Border Patrol agents have a choice of being issued either the Glock 47 or the Glock 19M pistol in 9mm caliber. The Glock 47 can contain as many as 18 rounds of ammunition (17 in the magazine and 1 in the chamber), while the Glock 19 can contain as many as 16 rounds. Up until 1995 the Border Patrol issued its patrol agents .357 Magnum revolvers as their duty sidearms, Smith & Wesson or Ruger model large frame, six-shot revolvers. The Border Patrol preferred this weapon because it did not jam in harsh conditions, like those of the southwestern border, and also because of the strong "stopping power" of the .357 Magnum cartridge. Although up until 1995 patrol agents could purchase weapons from the agency list of approved authorized personal weapons for duty carry. This list included the Glock Models 17 and 19 pistols in 9 mm, the SIG Sauer P220 pistol in .45 ACP caliber, the Colt Python .357 Magnum revolver, and the Smith & Wesson Model 19/66 .357 Magnum revolver. The Border Patrol adopted the Beretta Model 96D, a .40 S&W caliber semi-automatic pistol (modified for double-action only) (with 11-round capacity magazines) as its duty issue sidearm in 1995. The .40 S&W caliber jacketed hollow-point cartridge was adopted because of its excellent "stopping power" and its superior ballistic characteristics over the 9 mm cartridge. In late 2006 the H&K P2000 pistol was adopted as the Border Patrol's primary duty sidearm. The H&K Model USP compact pistol, H&K Model P2000SK (sub-compact) and Beretta M96D .40 S&W caliber pistols are authorized as secondary sidearms.

On April 9, 2019, CBP announced that the U.S. Border Patrol would transition from the .40 caliber H&K P2000 to an unnamed 9-millimeter Glock pistol, by the end of fiscal year 2021. It has since been revealed that the three Glock handguns that are to be issued to CBP officers and agents are the model G26, model G19, and the specifically manufactured for CBP model G47.

Like many other law enforcement agencies, the 12 gauge Remington Model 870 is the standard pump-action shotgun. The Border Patrol issue Model 870 has been modified by Scattergun Technologies to Border Patrol specifications including: a 14-inch barrel, a five-shot capacity magazine, a composite stock with pistol grip, and night sights with a tactical "ghost-ring" rear sight. The old Border Patrol "anti-bandit" units used to use 12-gauge, semi-automatic shotguns with sawed-off barrels. This weapon had the designated name of a "Sidewinder". The USBP anti-bandit units were decommissioned in the late 1980s.

Border Patrol agents also commonly carry the Colt M4 Carbine (specifically, the updated M4A1) using agency-issued 64-grain, .223 caliber ammunition and the H&K UMP .40 caliber submachine gun. The .308 caliber M14 rifle is used for ceremonial purposes and by agents who are qualified with the rifle and BORTAC.

As a less than lethal option, the Border Patrol uses the FN 303 launcher. The FN 303 fires 40mm plastic pellet balls containing OC (oleoresin capsicum) pepper dust. The plastic pellet balls burst on impact spraying the suspect with OC pepper dust and also acts as impact projectiles. The Border Patrol also issues its agents OC pepper spray canisters, tasers and a collapsible/telescopic (or telescoping) steel police baton.

### Transportation

Unlike in many other law enforcement agencies in the United States, the Border Patrol operates over 10,000 SUVs and pickup trucks, which are known for their capabilities to move around in any sort of terrain. These vehicles may have individual revolving lights (strobes or LEDs) and/or light bars and sirens and/or have their bumpers removed or have off-road suspension and tires. An extensive modernization drive has ensured that these vehicles are equipped with wireless sets in communication with a central control room. Border Patrol vehicles may also have equipment such as emergency first aid kits. Some sectors make use of sedans like the Ford Crown Victoria Police Interceptor or the Dodge Charger as patrol cars or high speed "interceptors" on highways. The U.S. Border Patrol has approximately 2,000 sedans. The Border Patrol also operates all-terrain vehicles, motorcycles, snowmobiles, and small boats in riverine environments.

In 2005, all Border Patrol and ICE aircraft operations were combined under CBP's Office of Air and Marine. All CBP vessel operations within the Customs Waters and on the high seas are conducted by Marine Interdiction Agents of the Office of Air and Marine.

Color schemes of Border Patrol vehicles are either a long green stripe running the length of the vehicle (older vehicles) or a broad green diagonal stripe (newer vehicles) on the door. Most Border Patrol vehicles are painted predominantly white. During the 1960s to mid-1980s Border Patrol vehicles were painted a light green.

The Border Patrol also extensively uses horses for remote area patrols. As of 2005, the U.S. Border Patrol has 205 horses. Most are employed along the Mexico–United States border. In Arizona, these animals are fed special processed feed pellets so that their wastes do not spread non-native plants in the national parks and wildlife areas they patrol.

## Killed in the line of duty

Since 1904, the Border Patrol has had 149 inspectors/officers/agents killed in the line of duty, more than any other federal law enforcement agency during that time period.

## Armed incursions

On March 14, 2000, 16 Mexican soldiers in two humvees chased a Border Patrol agent near Santa Teresa, New Mexico, while another agent came under gunfire. Backup arrived and nine of the soldiers were detained. The Mexican government said the soldiers were unfamiliar with the border in that area as those soldiers were normally deployed to Mexico's interior. The U.S. State Department ordered them sent back to Mexico along with their weapons.

On August 7, 2008, Mexican troops crossed the border into Arizona and held a U.S. Border Patrol Agent at gunpoint. Agents stationed at Ajo, Arizona, said that the Mexican soldiers crossed the border into an isolated area southwest of Tucson and pointed rifles at the agent, who has not been identified. The Mexicans withdrew after other U.S. agents arrived on the scene.

On May 24, 2022, 18-year-old Salvador Rolando Ramos entered Robb Elementary School in Uvalde, Texas, and fatally shot nineteen students and two teachers with an AR-15 rifle. Ramos had legally purchased two AR-15s and ammunition a few days earlier. Agents of U.S. Customs and BORTAC responded to the scene, and within minutes of their arrival, fatally shot Ramos, ending his 70-minute rampage. One agent suffered a injury.

## Death threats

Testifying in front of the United States Senate, Border Patrol Chief Mark Morgan said that the Border Patrol is the one of the most assaulted law enforcement agencies; since 2006, over seven thousand agents of the Border Patrol were attacked.On numerous occasions USBP agents have been fired upon from the Mexican side of the international border. Intelligence gathering has discovered bounties being placed on Patrol Agents to be paid by criminal smuggling organizations upon the confirmed murder or kidnapping of a U.S. Border Patrol Agent. In 2008, intelligence learned of a two-million-dollar contract for the murder of a Border Patrol Agent. In 2009 Border Patrol Agent Rosas was murdered in an ambush while on patrol; a bounty may have been paid to the assassins.
