== Description ==
The BM-21 (sometimes known as the M-210) is a 122 millimeter unguided explosive rocket that was utilized mainly by the former Soviet Union and its allies, and is still in service in many countries to this date. It is highly versatile and has been placed on various ground and naval vessels, in large rocket launcher batteries of up to 40 tubes in a turret.

== General info ==

=== Effective damage: ===
The HE warhead of the rocket with a TNT equivalent of about 10 kg provides a powerful explosive force that rivals that of battleships' main caliber guns (albeit with much less penetration due to comparatively low muzzle velocity.) capable of dealing splash damage between multiple enemies in close proximity to each other, and destroying most unarmoured targets in a single shot. These

=== Comparison with analogues ===
The BM-21 rocket is comparable to other unguided rockets like the [[HVAR]], [[Wgr.41 Spr]], and [[S-13OF]] in terms of firepower and penetrative capability. All of these rockets can decimate light vessels like torpedo boats in a single hit, crippling them and causing often fatal fires. However, in terms of ship-launched naval rockets, the BM-21 outclasses everything at its B.R due to its superior explosive mass and burn time range. Furthermore, the maximum effective range of the rocket is increased greatly by the fact that the fuel burns for almost the entire duration of flight, which is possible as it is almost 9 meters long and contains a lot of fuel.

== Usage in battles ==
Currently, this rocket is only present on a single vehicle in game, the Pr.183 BM-21, a motor gun boat at BR 3.0. It is best used as a naval 'artillery' weapon to saturate the capture points or enemy spawn with a barrage of powerful splash damage, which will take out most small boats in the area. However, should the circumstances permit, it can be used as a close support weapon against either groups of small enemy vessels or a single, larger craft. A number of well-placed shots against the weak points (e.g engine rooms or turret ammo storage) of much larger craft such as destroyers will severely incapacitate or immobilize the vessel, or even destroy it if fires or breaches are not repaired quickly enough. It can penetrate the waterline hull armour of many of the bigger ships of the BR it is situated in.

=== Pros and cons ===
'''Pros:'''

* Powerful explosive mass deals good damage against all targets.
* Considerable armour penetration, capable of penetrating and destroying targets like the Maus, modern MBTs, and large ships. <ref>This external video demonstates the penetrative capabilities of the weapon between 0:08 and 0:42 seconds. https://www.youtube.com/watch?v=Xd4lK19tyMk</ref>

'''Cons:'''

* Potentially difficult to aim.
* Limited supply of the rockets on the craft.
* Relatively slow muzzle velocity

U139789109: Edited some minor changes with vocabulary and technical explanation, which were previously inadequate and clearly written by someone with little knowledge on the subject and the correct terminology used to describe it. Page not finished.

== General Information ==
A rocket is a type of ammunition that can be fired in flight, from a ground vehicle and from naval vessel. There are two main. groups of rockets: anti-ground and anti-aircraft.

Some rockets explode on impact and some have their own fuse. The rocket contains a thruster, fuel and explosive.

=== Vehicles carrying rockets ===
[[File:An SB2-C Helldiver firing a Tiny Tim rocket.jpg|alt=An SB2-C Helldiver firing a Tiny Tim rocket|thumb|An SB2-C Helldiver firing a Tiny Tim rocket]]For a list of vehicles see [[:Category:Suspended armaments|Suspended armaments]]. Most common on planes and helicopters it can also be found on ground vehicles and ships.[[File:RocketMotors.png|thumb|436x436px|Multi-nozzle rocket description]]

== Rocket structure ==
There are several types of rockets, but here is described Multi-nozzle rocket:

* '''Head'''
** Nose & base fuse - What ensures an explosion after impact
** High explosive - An explosive that destroys the target
** Igniter - It allows the rocket to be launched not only after impact, but also in the air
* '''Motor'''
** Cruciform propellant powder grain - Rocket fuel
** Grain support space - It ensures that the fuel does not overflow
** Central nozzle with blowout seal surrounded by eight other nozzles - Rocket propulsion
** Fins - For direct rocket flight

== Rocket groups ==
There are several types of rockets.

=== 'Dumb' rockets ===
The most common type of rocket are

===Proxy Fuse Rockets ===
They are used mainly for anti-aircraft purposes, and a notable example of a plane featuring this weapon is the [[F-89D]], an interceptor jet aircraft,

== Aiming Rockets ==
To make sure your rockets hit you have to take into account many factors like distance, relative motion and accuracy of rockets. Modern planes and helicopters have a ballistic computer which will do such calculations for you - the '''CCIP system.''' However, you still have to make sure you fire the rockets from a distance and angle where dispersion is low.

=== Planes ===
[[File:Rocket Aiming.jpg|thumb|The dumb rocket aiming crosshair.]]
On most pre-modern jet aircraft there is only a 'ladder crosshair' which helps aiming rockets. Each gap on the ladder is equal to 250 meters. One must still calculate the rocket 'bullet drop' phenomenon and adjust accordingly. On naval arcade mode, a rangefinder with meters distance is provided on most vehicles, and this can assist aiming of rockets.
