The BM-21 (Russian: Боевая Mашина Полевой реактивной системы М-21 Boevaya mashina Polevoĭ ryeaktivnoĭ sistemy M-21; English: Combat Vehicle rocket system, Field M-21) was a Soviet multiple rocket launcher system designed in 1964. Developed from the same principle as the Katyusha, the BM-21 was used as a mobile, long range artillery weapon, as it could fire large, heavy and powerful 122mm rockets in rapid succession (120 per minute) at a range of up to 20 kilometers (12.4 miles).

In Battlefield Vietnam, the BM-21 is issued to the North Vietnamese Army. It has space for two players: one driver and one gunner. Its main feature is its exceptionally effective armament, a multiple rocket launcher that the gunner uses. It can fire 10 rockets per reload, with a total of four reloads, at a rate of around 120 rockets per minute. Each rocket is equivalent in power to a rocket from a LAW, RPG-2, or RPG-7, and can cause devastating damage against almost any target. However, the disadvantage of using the BM-21 is its extremely light armor, meaning it can be destroyed in one tank shell or rockets. Its rocket launcher also has a high recoil, throwing off the player's aim by at least 15° with each shot, making constant firing largely ineffective and inaccurate at long range. As well, the reload for its rockets is very slow, taking nearly ten seconds to be ready to fire again. However, when used by a skilled gunner, the rockets can be effective against helicopters.

Single PlayerEdit

In Battlefield 3, the BM-21 is used by the PLR and RGF forces as seen in Single Player mode firing rockets at the aerial US forces. The player encounters, and destroys them at a firebase camp in the mission Thunder Run, as well as appearing in Rock And A Hard Place, while not being used as the Russians did not have time to prepare them to combat

Co-opEdit

The BM-21 appears in Co-op during the mission Exfiltration as scenery. They can be destroyed in this mission.

MultiplayerEdit

In multiplayer, the BM-23 appears in Armored Kill as the Russian artillery vehicle. The USMC counterpart is the M142 HIMARS. The vehicle can only hold one person, but has two seats. The operator must switch between the driver and gunner positions, preventing use of weapons while moving.

The BM-23 is slightly more nimble than its American equivalent, but has a large windscreen that exposes the driver to small arms fire.

Its main weapon system is a turret capable of swiveling 360° and firing six rockets in one salvo. The minimap can be expanded to show the impact areas, much like the behavior for the M224 Mortar after the matching patch. On level ground it has a minimum engagement distance of about 100 meters, and a maximum of about 700. The targeting reticule roughly corresponds to 50 meter increments, starting with 100m at the top and 400m at the bottom. Adjustments must be made when attacking other elevations, and when stationed on a slope.

Although the BM-23's model clearly has a 40-missile rack, it operates exactly like the M142 with its six-missile capacity.

A quirk in the projectile behavior allows them to pass through objects shortly after launch, reducing the risk of the operator injuring himself if firing near cover.

Although not equipped with close-range weapons, the Proximity Defense specialization surrounds the vehicle with smoke that can kill infantry and destroy enemy equipment at close range. Otherwise, the operator is vulnerable even to small arms fire through the windshield. The player can turn the vehicle away from anticipated enemy routes, but there is a delay as the weapon system must be turned towards target.

The TOW missile used by the vehicle fires at a higher trajectory and faster speed than the comparable ATGM Launcher for IFVs, but is otherwise the same.

The specializations available to mobile artillery vehicles focus mainly on alternate weapons and threat minimization:

IR Smoke - 400 points
Autoloader - 800 points
Proximity Scan - 1600 points
ATACMS Missile guided weapon for engaging other ground vehicles - 2500 points
Maintenance - 3500 points
Zoom Optics - 4500 points
Thermal Camo - 5500 points
TOW missile system for engaging targets by wire-guidance - 7000 points
Proximity Defense for killing infantry at close range - 9000 points

Air-Burst Missile for focus on infantry - Rocket Specialist assignment
Anti-Air Missile for focus on air vehicles - Anti-air Support assignment

TriviaEdit

When a Javelin missiles hits the vehicle, it will always kill the driver, no matter where it strikes.
Console players have to use their "Pause" map in order to observe impact sites, compared to PC players simply having to expand their minimap without having to pause.
