) and entered service in 1981, with fielding beginning in 1983.
The Bradley is designed for reconnaissance and to transport a nine-man rifle squad, providing them protection from small arms fire, while providing firepower to both suppress and eliminate most threats to friendly infantry. It is designed to be highly maneuverable and to be fast enough to keep up with heavy armor during an advance. The M2 holds a crew of three: a commander, a gunner, and a driver, and can carry six fully equipped soldiers as passengers.

The 25 mm automatic gun is not the weapon of choice for engaging tanks, but vehicle commanders, crews, and CALL and Army Infantry Center personnel have reported isolated instances in which the 25 mm automatic gun disabled older generation tanks. However, Army Materiel Systems Analysis Activity (AMSAA) officials stated that, on the basis of their assessment of combat vehicles in the Persian Gulf war, for the 25 mm automatic gun to incapacitate a tank it would have to be hit at close range in its more vulnerable areas.

Subsequent ammunition developments resulted in the M919
APFSDS-T (
Armor-Piercing Fin Stabilized Discarding Sabot with Tracer) round, which contains a finned depleted-uranium penetrator similar in concept to armor-piercing munitions used in modern tanks. The M919 was used in combat during the
2003 invasion of Iraq.
It is also armed with an
M240C machine gun mounted
coaxially to the M242, with 2,200 rounds of 7.62 mm ammunition. For engaging heavier targets, such as tanks, the Bradley has a
TOW missile system onboard. It was changed from the M2A1 model to fire TOW II missiles. M2 infantry Bradleys have firing ports for a number of
M231 Firing Port Weapons (FPWs; modified
M16 assault rifles), providing a button-up firing position to replace the top-side gunners on the old ACAV, though the M231 is rarely employed. Initial variants carried six, but the side ports were plated over with the new armor used on the A2 and A3 variants, leaving only the two rear-facing mounts in the loading ramp.
Protection

The M2's base armor consists of an all-around 1 inch (25.4 mm) thick aluminum hull (mix of no. 5083 and no. 7039 alloys), heavily sloped in the front and mostly vertical on the sides and rear. The bottom of the hull front has an additional 0.375 inch (9.5 mm) thick steel applique plate, primarily intended to protect against mines. Both sides of the vehicle have an additional 0.5 inch (12.7 mm) of high hardness steel armor consisting of two quarter-inch applique armor plates spaced 1 inch apart from each other, the first spaced 3.5 inches from the aluminum hull. The turret, unlike the hull, is armored only in steel. The M2A1 version has identical armor but adds a gas particulate filter unit for NBC protection. This armor offers protection against threats up to and including 14.5x114mm AP.
The M2A2 upgrade adds additional armor. More steel applique armor is added to the vehicle's front, requiring removal of the trim-vane. 1.25 inch (32 mm) steel plates were added to the hull sides, replacing the earlier applique armor, as well as to the front and sides of the turret. The new armor covered up the infantry firing ports on the vehicle's sides. Spaced laminate armor was added to the hull rear, and kevlar spall liners were added to critical areas. Options for

were also added. These armor upgrades added about 3 tons to the vehicle's weight.
Countermeasures
The use of aluminum armor and the storage of large quantities of ammunition in the vehicle initially raised questions about its combat survivability. Spaced laminate belts and high hardness steel skirts were added to later versions to improve armor protection, increasing overall weight to 33 tons. However, combat operations have not shown the Bradley to be deficient, with few losses. In friendly fire incidents in

Bradley squad and platoon organization
Since 1986, the U.S. Army has believed 9 to be the optimal number of individuals in a mechanized squad. Because of the limited room available for passengers in the Bradley, accommodating a full squad in the Bradley is accomplished by squad splitting.
A mechanized platoon consists of soldiers other than the squad members, and those soldiers must also ride in the vehicles. The original Bradley had room for 3 crew members and 6 passengers, called dismounts by the U.S. Army. An original mechanized platoon with four M2 Bradley vehicles included 12 crew and two infantry squads of 9 dismounts. Five other dismounts were also in the platoon and needed to be transported in the platoon's vehicles: the platoon leader, a radio-telephone operator, a medic, and two
forward observers whose role is to call for support fire from artillery and aircraft. Together they filled 35 of the 36 available spaces in the platoon's four vehicles. In the later M2A2 and M2A3 versions of the Bradley, the Army rearranged the interior stowage and created space for an extra dismount in each vehicle, resulting in spaces for 7 dismounts in each vehicle and a total of 40 soldiers in the four-vehicle platoon. With the extra men, the Army reorganized the Bradley platoon into 3 squads with 9 dismounts each. The Bradley crew of 12 stayed the same, thus there was room in the Bradleys for only one more dismount—the platoon leader. That new configuration did not leave room for the medic, platoon radio-telephone operator, or forward observers. In actual practice, however, units rarely have all the men they are assigned, so there is usually room for those extra soldiers.
Even with the extra space in the revised Bradleys, the squads were split among more than one Bradley. A split squad can be difficult to organize and control immediately after dismounting, especially when under fire and in complex terrain. The Army seeks to avoid that difficulty by requiring the GCV to carry the full 9-man squad. A four-vehicle GCV platoon will have room for 12 crew members and 36 dismounts. With three squads fully occupying three GCVs, the fourth GCV will have room for the platoon leader, forward observers, radio-telephone operator, and medic.

The vehicle entered service with the
U.S. Army in 1981, and 4,641 M2 variants have been produced since.
Even after the troubled development history of the Bradley, additional problems occurred after production started, as later detailed by Air Force Colonel
James G. Burton, who took part in the design and fielding process.
[James G. Burton, Col. ''The Pentagon Wars: Reformers Challenge the Old Guard'', Annapolis, Maryland: Naval Institute Press (1993). .] Burton advocated the use of comprehensive live fire tests against fully loaded military vehicles to check for survivability.
The Army and Navy agreed and established the Joint Live Fire testing program in 1984.
When testing the Bradley, disagreements occurred between Burton and the

" tests in which weapon systems would be fired at the Bradley that were known to be able to easily penetrate its armor.
Burton saw attempts to avoid such tests as dishonest, while the BRL saw them as wasteful as they already knew the vehicle would fail.
The disagreements became so contentious that a congressional inquiry was set up. As a result of the tests, additional improvements to vehicle survivability were added.
By May 2000, 4,641 M2s had been produced for the U.S. Army.
Saudi Arabia stated an interest in acquiring the Bradley in 1989, and began importing the vehicle in 1990. Bradley production concluded in 1995. A total of 6,785 M2/M3 Bradleys were produced, including 400 for Saudi Arabia.

The M2A3 variant began to replace the
M3A3 cavalry fighting vehicles in US Army armored reconnaissance units in 2014, as the increased ammunition loads carried by the M3A3s reduced the number of scouts that could be transported. In 2016, a reorganisation of reconnaissance unit structures and compositions saw large-scale replacements of
Humvees within these units with M2A3s, increasing the tactical mobility and maneuver warfare capabilities of US Army armored reconnaissance brigades.

Replacement

U.S. Army efforts to replace the Bradley began in the mid-1980s under the
Armored Systems Modernization program. The Army studied creating several vehicle variants under a common heavy chassis to replace main battle tanks and Bradleys. This effort was canceled in 1992 due to the collapse of the Soviet Union.
The U.S. Army began the
Future Combat Systems (FCS)
Manned Ground Vehicles program in 1999. This family of 18-ton lightweight tracked vehicles centered around a common chassis. It would consist of eight variants, including infantry carriers, scouting vehicles and main battle tanks. FCS was canceled in 2009 due to budget cuts.
In 2010, the Army began the

program to replace the M2 Bradley. Entries from BAE and General Dynamics were selected for evaluation. Concerns grew around the vehicle's proposed weight of around 70 tons.
The GCV program was cancelled in 2014 due to sequestration budget cuts.
In June 2018, the Army established the
Next Generation Combat Vehicle (NGCV) program to replace the M2 Bradley. In October 2018, the program was redesignated as the
Optionally Manned Fighting Vehicle (OMFV).
This program placed much of the cost burden of development on contractors, causing many competitors to drop out. In February 2020, the Army restarted the program, promising to take on more responsibility for funding.

M3
The M3 Bradley CFV is very similar to the M2 Bradley IFV (Infantry Fighting Vehicle) and is fielded with the same two-man 25 mm Bushmaster cannon turret with the coaxial 7.62 mm machine gun. It only varies from the M2 in a few subtle ways and by role. The M3 is classified as an armored reconnaissance and scout vehicle and does away with the firing ports found in the M2 series. The M3 carries more TOW missiles as well as more ammunition for its 25 mm and 7.62 mm guns.
M2A1
Introduced in 1986, the A1 variant included an improved TOW II missile system, a Gas Particulate Filter Units (GPFU) NBC system, and a fire-suppression system. In 1992, the M2A1s had begun being remanufactured to upgraded standards. The GPFU system was only connected to the vehicle commander, driver, and gunner, while the infantry squad had to use their own from
MOPP suits. A seventh infantryman was added just behind the center of the turret.

. M2A2s were all eventually modified to the M2A2 ODS or M2A3 standard.
M2A2 ODS/ODS-E

The "Operation Desert Storm" and "Operation Desert Storm-Engineer" improvements were based on lessons learned during the first Gulf War in 1991. The major improvements included an eye-safe laser rangefinder (ELRF), a tactical navigation system (TACNAV) incorporating the Precision Lightweight GPS Receiver (PLGR) and the Digital Compass Systems (DCS), a missile countermeasure device designed to defeat first-generation wire-guided missiles, and the
Force XXI Battle Command Brigade and Below (FBCB2) Battlefield Command Information System.
The internal stowage was further improved and a thermal imaging system was added for the driver. The infantry squad was again increased to seven men, six of whom sat facing each other on two 3-man benches in the passenger compartment, with the seventh back in the position behind the turret. An
MRE ('Meal, Ready-to-Eat') heater was added to the vehicle to assist in the preparation of food. With the retirement of the Dragon missile, the vehicle had the option of carrying

M2A3

Introduced in 2000, the A3 upgrades make the Bradley IFV totally digital, with upgraded or improved existing electronics systems throughout, improving target acquisition and fire control, navigation, and situational awareness. The survivability of the vehicle was upgraded with a series of armor improvements, again both passive and reactive, as well as improved
fire-suppression systems and
NBC equipment.
The A3 Bradley incorporates the Improved Bradley Acquisition Subsystem (IBAS) and the Commander's Independent Viewer (CIV). Both include a second-generation
forward looking infrared

(FLIR) and an electro-optical/TV imaging system. The IBAS has direct-view optics (DVO) and the eye-safe laser rangefinder (ELRF).
[Field Manual 3-22.1, Bradley Gunnery (Nov 2003). Headquarters, Department of the Army.] The CIV allows the commander to scan for targets and maintain situational awareness while remaining under armor, and without interfering with the gunner's acquisition and engagement of targets.
[Hans Halberstadt (2001). ''Europa Militaria No 30: Bradley Company.'' Ramsbury, Marlborough, Wiltshire: The Crowood Press Ltd. .]

The A3's fire control software (FCSW) combines laser range, environmental readings, ammunition type, and turret control inputs to automatically elevate the gun for range and to automatically generate a kinematic lead solution if a target is moving.
This functionality, very similar to that of the M1A2 Abrams, allows the gunner or commander to center the reticule on a moving target, lase the target, and achieve a first-round-hit, without the need to fire sensing rounds and adjust aim.
[Michael Green & James D. Brown (2007). ''M2/M3 Bradley at War.'' St. Paul, MN: Zenith Press. .] The FCSW incorporates a thermal aided target tracker (ATT) function that can track two targets in the FLIR field of view and switch between them, primarily intended for employing TOW missiles against moving vehicles.
The FCSW allows the turret and gunner's sights to be slewed automatically onto a target that has been designated with the CIV.
The A3 Bradley uses a position-navigation subsystem that incorporates a
global positioning system
The Global Positioning System (GPS) is a satellite-based hyperbolic navigation system owned by the United States Space Force and operated by Mission Delta 31. It is one of the global navigation satellite systems (GNSS) that provide ge ...
(GPS), an
inertial navigation unit (INU), and a vehicle motion sensor (MVS),
which, in addition to allowing accurate own-vehicle navigation, allows accurate position reporting and the ability to hand-off designated targets to other units via FBCB2.
The Commander's Tactical Display (CTD) presents information from the FBCB2 and the vehicle navigation systems on a moving-map display. This allows the commander to communicate via text over FBCB2, and allows him to check vehicle built-in test (BIT) information and access various other information.
The Squad Leader's Display (SLD) in the infantry compartment improves the situational awareness of the passengers by allowing them to view navigational information from the FBCB2 and imagery from the IBAS, CIV, or Driver's Vision Enhancer (DVE) to familiarize themselves with their surroundings prior to dismounting.
The M2A3 Bradley II, and an M2A3 Bradley variant used in Iraq, were included in the GCV Analysis of Alternatives.
M2A4
After the Iraq War, the Army began to research engineering change proposals (ECPs) for the M2 Bradley to restore space, weight, power, and cooling capacity reduced by the addition of armor and electronics hastily added during combat. ECP1 will work to restore mobility and allow the vehicle to handle more weight. As its weight increases, the Bradley sits lower on its suspension, which reduces its ground clearance. This decreases mobility on rough terrain and leaves the vehicle more vulnerable to IEDs.
[Army Develops New Concepts, Keeps Existing Fleets Rolling](_blank)
- Defensenews.com, 12 October 2014[Upgrades 'new normal' for armor in uncertain budget environment](_blank)
- Army.mil, 20 October 2014 The effort will install lighter tracks, shock absorbers, a new suspension support system, and heavy weight torsion bars. The Army will upgrade its entire active fleet of Bradleys with ECP 1, this comes out to 3,344 vehicles with the final upgrades being procured in FY22.


ECP2 will restore automotive power with a larger engine, a new transmission, and a smart-power management system for better electrical power distribution to accept future networked tactical radio and battle command systems.
The first Bradleys upgraded with ECP1 were fielded in mid-2015, and the first to be upgraded with ECP2 will begin fielding in 2018. Vehicles that receive both the ECP1 and ECP2 upgrade will be designated A4.
In June 2018, BAE Systems Land and Armaments was awarded a contract to produce up to 164 M2A4 and M7A4 Bradley Fighting Vehicles using existing M2A3, M7A3 and M2A2 ODS-SA Bradleys. The M2A4 is equipped with an enhanced drivetrain, a more powerful engine, new digitized electronics, a new fire suppression system, and a new IED jammer.
The first M2A4 models were fielded in April 2022. The US Army program of record for M2A4 and M7A4 vehicles as of March 2023 was 731, enough for four CONUS armored brigades as well as one European Defense Initiative armored brigade and TRADOC vehicles.
In April 2024, the U.S. Army unveiled the M2A4E1 Bradley with the
Iron Fist active protection system integrated.
Mission Enabler Technologies-Demonstrator
The MET-D is an experimental variant of the M2 Bradley which prototypes the use of surrogate
robotic combat vehicles (RCVs) that are operated by the crew of the MET-D. It is equipped with a
remote turret for the main 25mm chain gun, 360-degree situational awareness cameras and enhanced crew stations with touchscreens.
Other uses of the Bradley chassis
The Bradley series has been widely modified. Its chassis is the basis for the
M270 Multiple Launch Rocket System, the M4 C2V battlefield command post, and the M6 Bradley Linebacker air defense vehicle. Armed with a quad Stinger surface-to-air missile launcher in place of the
TOW anti-tank missiles, but maintaining the 25 mm autocannon, the M6 Bradley Linebacker Air Defense Vehicle (no longer in service) possessed a unique role in the
U.S. Army, providing highly mobile air defense at the front line.
The Bradley's suspension system has been used on upgraded versions of the
U.S. Marines'
Assault Amphibious Vehicle.
