==General Information==

'''Battle rating''' (BR) is a value used to determine matchmaking in War Thunder. Battle rating is a number assigned to every aircraft, ground unit, and naval vessel in the game that correlates with their effectiveness in combat. Roughly speaking, as a vehicle's capabilities and performance increase, so does its battle rating. Battle rating can also differ depending on the game mode. For example, if a vehicle may perform considerably better compared to its opponents in Arcade Battles than in Realistic Battles, it may have a higher battle rating in the former.

'''Battle rating does not correspond with real-life introduction dates, but rather, the vehicle's in-game performance.''' Even if major technological imbalances existed among the vehicles in real life, the battle rating system allows War Thunder to remain balanced at all ranks by only matching vehicles with similar in-game performance against each other.

Battle ratings exists in steps of 0.3 or 0.4 starting from 1.0 and ending at 11.0 (i.e. 1.0, 1.3, 1.7, 2.0, 2.3, 2.7,etc.).

{{Notice|Matchmaking is based solely on battle rating; the rank of a vehicle is irrelevant.}}

The battle rating of every vehicle can be found at the top of its stat card or in the lower-right corner of its icon in the Research screen. To check the vehicle's BR in different game modes, select the appropriate mode in the drop-down menu lower-right corner of the Research screen. Note that the BR of "Reserve" vehicles in 1.0.

The battle rating that the [[Matchmaker]] will use will always be displayed at the top of the screen, underneath "To Battle!".

==Aviation==

===Air Arcade Battles===

In Air Arcade Battles, matchmaking is determined by the '''total battle rating''' of a lineup, which is calculated based on the three highest BR aircraft of that lineup. Ground units and naval vessels in the lineup cannot be taken into battle and will have no effect on the calculation of total battle rating. Damaged aircraft, or aircraft that are on [[Crew lock]], will not be factored into calculation either.

In general:

* Total BR will only be lowered if there is only one aircraft with the highest BR in the lineup (e.g. one 5.0, with all else 4.7 or lower).

* Total BR can be lowered by a maximum of one BR step below the highest BR aircraft (e.g. 5.0 to 4.7, 3.7 to 3.3).

* Only BR differences of up to 2.0 are taken into consideration; otherwise, total BR is taken from the highest BR.

Players will only be matched against other players based on their total battle rating. They may be able to see players with a total BR as low or as high as their own total BR ±1.0. For example, if a player's total BR is 3.0, they can be matched with players with total BR between 2.0 and 4.0.

=====Calculation=====

If '''A''' is the highest BR in a lineup, '''B''' is the second highest BR, and '''C''' is the third highest BR, then the formula for '''Total BR''' is as follows:

:'''Total BR''' = ('''A''' ÷ 2) + ('''X''' ÷ 4) + ('''Y''' ÷ 4)

where:

* If '''A''' - '''B''' < 0.6, then:

:: '''X''' = '''B'''

* If 0.6 ≤ '''A''' - '''B''' ≤ 2.0, then:

:: '''X''' = '''A''' - 0.6

* If '''A''' - '''B''' > 2.0, then:

:: '''X''' = '''A'''

* If '''A''' - '''C''' < 0.6, then:
[1] Kalıcı Yüzleşme: 1.0 — 2.0
[2] Kalıcı Yüzleşme: 2.3 — 3.3
[3] Kalıcı Yüzleşme: 3.7 — 4.7
[4] Kalıcı Yüzleşme: 5.0 — 6.3
[5] Kalıcı Yüzleşme: 6.7 — 7.7
[6] Kalıcı Yüzleşme: 8.0 — 9.3
[7] Kalıcı Yüzleşme: 9.7 — 11.0
:: '''Y''' = '''C'''

* If 0.6 ≤ '''A''' - '''C''' ≤ 2.0, then:

:: '''Y''' = '''A''' - 0.6

* If '''A''' - '''C''' > 2.0, then:

:: '''Y''' = '''A'''

In other words, if the difference between '''A''' and '''B''' is less than 0.6, then '''B''' is substituted for '''X''' in the equation. If the difference is between 0.6 and 2.0, inclusive, then ('''A''' - 0.6) is substituted for '''X'''. If the difference is greater than 2.0, then '''A''' is substituted for '''X'''.

The value of Y is calculated the same way, except the difference between '''A''' and '''C''' is compared instead.

Once evaluated, the resulting value '''Total BR''' is rounded to the nearest battle rating step. For example, 3.1 (which is closer to 3.0 than 3.3) will be rounded down to 3.0, and 3.2 (which is closer to 3.3 than 3.0) will be rounded up to 3.3.

Values exactly between two steps are rounded up. For example, 3.15 (which is exactly between 3.0 and 3.3) will be rounded to 3.3, and 3.5 (which is exactly between 3.4 and 3.7) will be rounded to 3.7.

====Example Calculation====

Here is an example calculation of total battle rating, where:

: '''A''' = 6.0
: '''B''' = 5.7
: '''C''' = 5.0

First, the difference between '''A''' and '''B''' is checked. The difference is 0.3, so:

: '''X''' = '''B''' = 5.7

Now, the difference between '''A''' and '''C''' is checked. The difference is 1.0, so:

: '''Y''' = '''A''' - 0.6 = 5.4

Substituting these values into the equation:

:'''Total BR''' = ('''6.0''' ÷ 2) + ('''5.7''' ÷ 4) + ('''5.4''' ÷ 4) = '''5.775'''

The resulting value, '''5.775''', is closer to 5.7 than 6.0, so the value is rounded down to '''5.7'''.

Thus, for a lineup whose highest BRs are 6.0, 5.7, and 5.0, the '''Total BR''' of the lineup is '''5.7'''.

===Air Realistic Battles===

In Air Realistic Battles, only the aircraft currently selected will be taken into battle, and its battle rating will be used to determine matchmaking. Players will only see aircraft with battle rating ±1.0 compared to their own.

===Air Simulator Battles===

In Air Simulator Battles, there are two battle rating ranges for each team, '''Allowed vehicles''' and '''Required vehicles'''. Any aircraft with battle rating in the '''Allowed vehicles''' range can be taken into battle. However, to enter an Air Simulator game, at least one aircraft in the lineup must be in the '''Required vehicles''' range. Players are matched with other players whose lineups consist of vehicles in the '''Allowed vehicles''' range.

Typically, in an Air Simulator game, lower battle rating vehicles can spawn immediately, while higher battle rating vehicles may require Spawn Points (SP) and may have a cooldown timer until they can be spawned again.

Ground units and naval vessels in the lineup are not taken into account and cannot be taken into battle. Neither can damaged vehicles or vehicles on [[Crew lock]].

===Air Arcade Assault===

In Air Arcade Assault mode, there are battle rating ranges as follows:

* 1.0 - 2.3
* 2.7 - 3.7
* 4.0 - 5.0
* 5.3 - 6.3
* 6.7+

The battle rating of the highest BR aircraft in a lineup is used to determine which range a player will be matched in.

Ground units and naval vessels in the lineup are not taken into account and cannot be taken into battle. Neither can damaged vehicles or vehicles on [[Crew lock]].

==Ground Forces==

===Ground Arcade Battles===

In Ground Arcade Battles, the battle rating of the highest BR ground vehicle, with players only able to see ground units with BR ±1.0.

Aircraft and naval vessels in the lineup are not taken into account and cannot be taken into battle. Neither can damaged vehicles or vehicles on [[Crew lock]].

===Ground Realistic Battles===

In Ground Realistic Battles, the batting rating of the highest BR ground vehicle or aircraft (including helicopters) is used, with players only able to see ground units and aircraft with BR ±1.0.

For example, for a lineup consisting of a BR 5.0 ground unit and a BR 5.3 aircraft, the BR of the aircraft is taken, and vehicles with BR between 4.3 and 6.3 can be seen.

Naval vessels in the lineup are not taken into account and cannot be taken into battle. Neither can damaged vehicles or vehicles on [[Crew lock]].

===Ground Simulator Battles===

In Ground Simulator Battles, battle rating is irrelevant in matchmaking. Only vehicles listed on the '''Allowed vehicles''' list can be taken into battle, with at least one vehicle from the '''Required vehicles''' list (if applicable) required to enter the game.

Any vehicle not listed in either the '''Allowed vehicles''' list will not be taken into battle. Neither can damaged vehicles or vehicles on [[Crew lock]].

===Ground Arcade Assault===

In Ground Arcade Assault mode, there are battle rating ranges as follows:

* 1.0 - 2.3
* 2.7 - 3.7
* 4.0 - 5.0
* 5.3 - 6.3
* 6.7 - 8.0
* 8.3+

The battle rating of the highest BR ground unit or helicopter in a lineup is used to determine which range a player will be matched in.

Aircraft and naval vessels in the lineup are not taken into account and cannot be taken into battle. Neither can damaged vehicles or vehicles on [[Crew lock]].

==Naval Forces==

===Naval Arcade Battles===

In Naval Arcade Battles, the battle rating of the highest BR naval vessel is used, with players able to see naval vessels and aircraft with BR ±1.0. Aircraft with BR up to one BR step above the highest BR naval vessel can also be taken. If the BR of the aircraft exceeds the BR of the naval vessel, its BR will be used instead.

For example, for a lineup consisting of a BR 2.0 naval vessel and a BR 2.3 aircraft, the BR of the aircraft is taken, and vehicles with BR between 1.3 and 3.3 can be seen. For a lineup consisting of a BR 2.0 naval vessel and a BR 2.7 aircraft, the aircraft will not be taken into battle and vehicles with BR between 1.0 and 3.0 will be seen.

Ground units in the lineup are not taken into account and cannot be taken into battle. Neither can damaged or vehicles on [[Crew lock]].

===Naval Realistic Battles===

In Naval Realistic Battles, matchmaking works the same way as in Naval Arcade battles. The battle rating of the highest BR naval vessel is used, with players able to see naval vessels and aircraft with BR ±1.0. Aircraft with BR up to one BR step above the highest BR naval vessel can also be taken. If the BR of the aircraft exceeds the BR of the naval vessel, its BR will be used instead.

For example, for a lineup consisting of a BR 2.0 naval vessel and a BR 2.3 aircraft, the BR of the aircraft is taken, and vehicles with BR between 1.3 and 3.3 can be seen. For a lineup consisting of a BR 2.0 naval vessel and a BR 2.7 aircraft, the aircraft will not be taken into battle and vehicles with BR between 1.0 and 3.0 will be seen.

Ground units in the lineup are not taken into account and cannot be taken into battle. Neither can damaged vehicles or vehicles on [[Crew lock]].

==Squads==

In any game mode except for Air and Ground Forces Simulator Battles, when playing in a squad, the Matchmaker uses the highest battle rating within the squad. For Air AB, the highest total BR within the squad is used.

For example, in Air RB, for a squadron consisting of a BR 4.7 aircraft and a BR 5.7 aircraft, the BR of the higher aircraft is used, and both players will be put into matches where they can see aircraft with BR between 4.7 and 6.7.

U110692667: /* Matching according to lists */

'''The matchmaker''' (balancer) is a server tool that is responsible for creating game sessions in all multiplayer game modes. The opponents you will meet in battle comes from the matchmaker.

== Matchmaker in main game modes ==
3 main difficulty game modes are represented in War Thunder: Arcade, Realistic and Simulator. They differ from each other by rules on how the vehicles will be used during one battle - whether it’s one single vehicle or even the whole setup of vehicles. Based on these differences the matchmaker works according to different rules guided in most cases only by the Battle Rating of the participating vehicles.

{{Notice
|'''Battle rating (BR)''' — is the index of efficiency of each vehicle in the game for each of the three game modes (difficulty modes). Which opponents the player may meet in battle with this vehicle depends on the BR.
}}

By clicking the “To Battle” button the player enters the queue for the selected game mode. Depending on the rules of the game mode chosen, the matchmaker collects players from the queue to the game session based on the BR of the particular vehicle or the whole vehicle line up which has been selected for the crew slots. In this case matchmaker doesn’t take into account a BR of any vehicle which isn’t suitable for the selected game mode or is broken - such vehicles will be highlighted in gray or red in the crew slots before clicking the “To Battle” button.

=== Matchmaking types ===
{| class="wikitable" style="text-align:center;"

|-
| AB || Average BR || Highest BR || Highest BR
|-
| RB || Highest BR || Highest BR || Highest BR
|-
| SB || BR range || According to the lists || —
|}

== General rules of the matchmaking based on BR ==
The matchmaker selects the game session for the player in which the spread of the opponent’s vehicle BR will not exceed +/- 1.0 BR from the player’s vehicle. This means that the player will not meet a vehicle which exceeds the BR of his key vehicle (the one on which the matchmaker bases its search for a game session) in battle by more than 1 point of the BR.

=== Additional rules ===

* By searching for the team within the maximum spread (+/- 1.0 BR) the number of players in the vehicles with the highest BR in each team will not exceed 4 players.
* In aircraft RB there is a limit of 5 bombers from the total number of the team.

These are all the rules that the matchmaker uses in random battles. There are no exceptions such as matching by player performance statistics at all.

== Matchmaking based on the average BR ==
Matchmaking takes 3 vehicles with the highest BR from a players setup (vehicles from the crew slots) and displays the average value.

This method of matchmaking will be used in aircraft AB. It allows you to research more advanced vehicles whilst not refusing the already researched aircraft as a player’s new aircraft can participate in the battles at a slightly lower BR where it is more comfortable to research its modifications.

=== Averaging formula ===
To get the average BR in such matchmaking only 3 aircraft will be counted with the highest BR from the whole player’s setup (vehicles from crew slots).

It will be calculated with the following this formula: BR=A/2+B/4+C/4

* A — vehicle with highest BR..
* B and C — 2 vehicles with bit lower BR.

A final value will be rounded up to the nearest tenth from the list of values 0.3 or 0.7 (steps of BR in the game).

=== Additional rules ===

* If the difference in the BR between the vehicle with highest BR (A) and one of the top vehicles (B or C) is higher than 0.6, so in matchmaking the BR for this top vehicle will be calculated as A-0.6. It means that if A-B(C) > 0.6 so B(C) = A - 0.6.
* If the difference in the BR between the vehicle with highest BR (A) and one of the top vehicles (B or C) is equal to or higher than 2.0, so in matchmaking the BR of such a top vehicle will be replaced by BR of vehicle A. It means that if A-B(C) ⩾ 2.0, so B(C) = A.
* If you want to send less than 3 vehicles into battle (specifically the number of serviceable aircraft in the crew slots is less than 3), so the BR values for the missing aircraft in the formula will be counted as A-0.6.

== Matching based on the highest BR ==
The matchmaker takes the vehicle with the highest BR from the whole player’s setup or the BR of the single vehicle selected for battle and matches it to a game session based on such a vehicle.

Such a method of selection is optimal for ground vehicles and naval vessels where the differences in the technical characteristics and the battle capabilities play a bigger role than in only aircraft battles.

{{Notice
|For the convenience of participation in different game modes we have a mechanism of “vehicle presets” which allows us to save several variants for vehicle arrangement in the crew slots.
|+
}}

== Matching based on the BR range ==
In this matchmaking mode the rule of BR spread +/- 1.0 isn’t operating. The player will join the game session with fixed BR ranges, from minimum to maximum BR , which can be wider than +/- 1.0.

Determining which range the player enters is based on the rule of “Matching based on the highest BR”. This means with the vehicle with the highest BR from the crew slots.

{{Notice
|Such kind of matchmaking will be used in SB. At the very beginning of the battle the player can only use the vehicle with a minimum BR that is equal to the initial BR in the range. More advanced vehicles will open for Respawn Points which can be earned in the game session.
|!
}}

BR distribution based on the range looks like the following:

* [1] Enduring Confrontation: 1.0 — 2.0
* [2] Enduring Confrontation: 2.3 — 3.3
* [3] Enduring Confrontation: 3.7 — 4.7
* [4] Enduring Confrontation: 5.0 — 6.3
* [5] Enduring Confrontation: 6.7 — 7.7
* [6] Enduring Confrontation: 8.0 — 9.3
* [7] Enduring Confrontation: 9.7 — 11.0
