==Battle Ratings==
+
==General Information==
Battle ratings are used by War Thunder to determine matchmaking in-game. Battle ratings are calculated by examining how well an aircraft or ground unit fares in different game modes, and they may differ for each game mode for the same vehicle (for example, an aircraft or ground unit may perform considerably better in arcade mode than realistic battles mode, and so will have a higher battle rating in the former). This allows for a balanced game at all ranks and using all vehicles, meaning that certain nations having technological advantages at different periods in the game's timeline is not an issue when playing, and planes that are too powerful do not ruin gameplay for those flying less effective aircraft.

====In Arcade mode====
 
  
For Arcade Air Battles, a formula is in place that calculates your overall Battle Rating, aka the Battle Rating that the Matchmaker will use to match opponents against you, based on the three highest aircraft in your lineup in regards to their individual BR.
+
Battle rating (BR) is used to determine matchmaking in War Thunder. It 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.
  
That said, the important thing for you to know are three short facts:
+
'''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.
* The overall BR can be lowered by a maximum of one BR step (e.g. 5.0 to 4.7, or 3.7 to 3.3) based on the aircraft in your lineup.
 
* Lowering your overall BR only works if you have only one aircraft with the highest BR in your lineup (e.g. one on BR 5.0, all others are at least 4.7 or lower).
 
* The formula takes aircraft of up to 2.0 difference in BR into consideration (e.g. for 5.0, 3.0 is the maximum difference).
 
  
What does that mean for you, as a player? As you progress through the research trees, it may happen that you unlock a new aircraft of considerably higher BR than the other aircraft in your current lineup. This system, to a certain extent, will allow you to use this new aircraft, while keeping your overall lineup competitive against other players you may face.
+
Battle ratings exists in steps of 0.3 or 0.4 starting from 1.0 and ending at 10.3 (i.e. 1.0, 1.3, 1.7, 2.0, 2.3, 2.7,etc.).
  
The maximum amount that you can lower your overall BR is one step. So, as an example, a 5.0 maximum BR based on your highest aircraft can at best be lowered to 4.7, but only if there are no other 5.0 aircraft in your lineup. The same is true for e.g. a 3.7 lineup, which can be lowered by one step to 3.3 at best. Thus, while this system is helpful to stay competitive with an otherwise "weaker" lineup, you will still be better off equipping multiple aircraft of similar BR (e.g. several 5.0 ones) to maximize the combat effectiveness of your overall lineup - if you have such aircraft available.
+
{{Notice|Matchmaking is based solely on battle rating; the tier of a vehicle is irrelevant.}}
  
===== Calculation example =====
+
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.
Basically, that is all you need to know. If you are interested in the calculation itself, however, here we go:
 
  
'''A''' is your aircraft with the highest BR, '''B''' and '''C''' are the two aircraft following '''A''' in regards to BR.
+
The battle rating that the [[Matchmaker]] will use will always be displayed at the top of the screen, underneath "To Battle!".
  
If the difference between '''A''' and '''B''' (the same goes for '''A''' and '''C''') is greater than 2.0, the value of '''A''' will be used instead of '''B''' (or '''C''', respectively).
+
==Aviation==
  
If the difference of '''A''' and '''B''' (the same goes for '''A''' and '''C''') is smaller than 2.0, but greater than or equals 0.6, the value "'''A''' - 0.6" will be used instead of '''B''' (or '''C''', respectively).
+
===Arcade Battles===
  
If the difference of A and B (the same goes for '''A''' and '''C''') is smaller than 0.6, B will be used (or '''C''', respectively).
+
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.
  
After our variables have been established, the following formula applies:
+
In general:
  
Overall BR = '''A'''/2 + '''B'''/4 + '''C'''/4
+
* 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).
  
An example to show how the calculation works:
+
* Total BR can be lowered by a maximum of one BR step below the highest BR aircraft (e.g. if 5.0 to 4.7, 3.7 to 3.3).
  
'''A''' = 6.0; '''B''' = 5.7; '''C''' = 5.0
+
* Only BR differences of up to 2.0 are taken into consideration; otherwise, total BR is taken from the highest BR.
  
At first, we check if the difference between '''A''' and '''B''' or '''C''' is greater than 2.0 - if that would be the case, we would use the value of '''A''' instead. Neither the difference of '''A''' and '''B''' (0.3) or '''A''' and '''C''' (1.0) is greater than 2.0.
+
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.
  
Now, we check if the difference between '''A''' and '''B''' or '''C''' is smaller than 2.0 but greater than or equals 0.6 - if that would be the case, we would use the value of "'''A''' - 0.6" instead. This is not the case for '''A''' and '''B''' (0.3), but for '''A''' and '''C''' (1.0) it is true. So for '''C''', we use the value of "'''A''' - 0.6", which is 5.4.
+
=====Calculation=====
  
As the difference of '''A''' and '''B''' is smaller than 0.6, we use the regular value of '''B''', which is 5.7.
+
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:
  
So, for our formula, we use:
+
:'''Total BR''' = ('''A''' ÷ 2) + ('''X''' ÷ 4) + ('''Y''' ÷ 4)
  
Overall BR = ('''6.0''' / 2) + ('''5.7''' / 4) + ('''5.4''' / 4) = 5.775
+
where:
  
Our value will be rounded to the next BR step. For clarification: Values like 3.15 will be rounded to 3.3, or 3.85 will be rounded to 4.0, while e.g. 3.45 will be rounded to 3.3. If the calculated value results in a number right in the middle of two BR steps (e.g. 3.85, which lies between 3.7 and 4.0), it will always be rounded up.
+
* If '''A''' - '''B''' < 0.6, then:
 +
:: '''X''' = '''B'''
  
As a result, our overall BR for our Arcade Air Battles lineup of "6.0, 5.7 and 5.0" is now '''5.7'''.
+
* If 0.6 ≤ '''A''' - '''B''' ≤ 2.0, then:
 +
:: '''X''' = '''A''' - 0.6
  
===== Table example =====
+
* If '''A''' - '''B''' > 2.0, then:
Some more lineups as an example:
+
:: '''X''' = '''A'''
 +
 
 +
* If '''A''' - '''C''' < 0.6, then:
 +
:: '''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'''.

===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.
 +
 +
===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 vehicle 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 Assault===
 +
 +
In Air 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==
 +
 +
===Arcade Battles===
 +
 +
In Ground Forces Arcade Battles, the battle rating of the highest BR ground unit, 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.
 +
 +
===Realistic Battles===
 +
 +
In Ground Forces Realistic Battles, the batting rating of the highest BR ground unit or aircraft 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.
 +
 +
===Simulator Battles===
 +
 +
In Ground Forces 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.
 +
 +
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 Assault===
 +
 +
In Ground 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 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.
  
====In [[Realistic_Battles|Realistic]] and [[Simulator Battles|Simulator battle]] modes====
+
==Naval Forces==
In these two modes, the battle rating system works the same, however as the player is only using one aircraft or ground unit, the battle rating system will not take in to account the other aircraft in their lineup, and they will only fight enemies with aircraft or ground units within the battle rating range of the one they have selected.
+
 
</div>
+
===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 2.0 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.
 +
 
 +
===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.
 +

General Information

Battle rating (BR) is used to determine matchmaking in War Thunder. It 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 10.3 (i.e. 1.0, 1.3, 1.7, 2.0, 2.3, 2.7,etc.).

Msg-info.png Matchmaking is based solely on battle rating; the tier 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!".

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. if 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:
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.

Tablular Examples

Some example lineups:

A B C Overall BR
8.0 7.7 7.7 8.0
5.0 4.3 4.0 4.7
4.0 4.0 2.0 4.0
3.7 3.0 2.7 3.3
5.0 1.0 1.0 5.0

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.

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 vehicle 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 Assault

In Air 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

Arcade Battles

In Ground Forces Arcade Battles, the battle rating of the highest BR ground unit, 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.

Realistic Battles

In Ground Forces Realistic Battles, the batting rating of the highest BR ground unit or aircraft 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.

Simulator Battles

In Ground Forces 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.

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 Assault

In Ground 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 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

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 2.0 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.

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 2.0 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.
