Replay Analysis Part 4: Vehicle Class

Welcome to Part 4 of my Replay Analysis where I analyse over 66,000 replays sent to me by you. Today we’ll be focusing on the Vehicle Class.

I’ve spent some time adding the Vehicle Class and Nation to my data sheet, so Part 5 will focus on the Nation of the vehicle the player in the replay was driving, and Part 6 will focus on the Range. Part 6 will conclude the first round of analysis before I take a deeper look into specific areas. You can read all other parts of the Replay Analysis here.

When referring to Vehicle Class in this analysis, at all times I am referring to the vehicle the player was driving in the replay. i.e. if I have a replay where the player in focus was driving the Type 64, the class of that replay is considered to be a Light Tank. I have been tinkering with an older replay analyser recently and hope to be able to get statistics of other players within the battle, which will enable me to look deeper into some statistics, such as, how many battles had 0, 2, 4, or 6 SPG’s, or does the number of Tank Destroyers in a Battle and the Battle Duration correlate at all?

But first, some quick definitions:

  • HT = Heavy Tank
  • MT = Medium Tank
  • LT = Light Tank
  • TD = Tank Destroyer
  • SPG = Artillery / SPG

The colors used for the charts in this post correspond with the vehicle colors used in Aslains Modpack (Heavy, Medium, Light, Tank Destroyer, SPG) with the exception of the Spread chart, which utilizes the common XVM Red to Purple color scheme for spreads -2 to +2.


50,253 Standard, Random Battle Replays had the complete data and were included in this part of the Analysis. 29,475 (59%) were from the EU Region and 20,778 (41%) from the NA Region.

64.67% of all battles from the NA Region were played in SPG's, with the EU Region being more diverse, but still with a leading majority in Medium Tanks (36.37%). Light Tanks were the least played vehicle for NA (5.12% of all NA battles), and SPGs were the least played for EU (7.92%).

14.83% of all battles were in Heavy Tanks, 25.13% in Medium Tanks, 11.31% in Light Tanks, 17.34% in Tank Destroyers, and 31.39% in SPG's.

How do I define Matchmaking Spread? - Click to expand

There are six possible spreads: -2, -1, -1/+1, =, +1 and +2. At all times during the analysis, -2 means in the replay analysed, the player was bottom tier by two; -1: bottom tier by one; -1/+1: mid tier; =: same tier; +1: top tier by one; and +2: top tier by two. For example, -2 could mean the player was in their Tier 8 vehicle matched with Tier 9's and 10's and = could mean the player was in their Tier 6 vehicle matched with only Tier 6's.

By coincidence, there are six main colors in XVM: Red, Orange, Yellow, Green, Cyan and Purple. In the infographics, the spreads will be colored the same for continuity: -2: Red, -1: Orange, -1/+1: Yellow, =: Green, +1: Cyan and +2: Purple.

Unique Conditions

In Random Battles, it is not possible for:

  • Tier 1 to be +1
  • Tier 1, 2, and 3 to be -2, -1/+1, or +2
  • Tier 10 to be -1 or -1/+1
  • Tier 9 and 10 to be -2

Low tiers do not play on every map. Wargaming change the map rotation every so often and don't shout about it, making it very difficult to separate these battles from the data. However, I feel this is not vitally important, as the focus is likely to be on Tier 6 and above.

The least common spread for each class was:

  • Heavy: +2 (8.31% of all Heavy Tank Battles were of +2 Spread)
  • Medium: +2 (7.22%)
  • Light: +2 (2.66%)
  • Tank Destroyer: +2 (7.86%)
  • SPG: -2 (2.46%)*

Equal Spread was the most common for all classes.

If we transpose the data to focus on the Spread first, we can see the most common vehicle class to feature in each Spread:

  • -2: Medium (37.28% of all -2 Spread battles were in Medium Tanks)
  • -1: Medium (32.64%)
  • -1 / +1: Medium (34.58%)
  • =: SPG (42.51%)**
  • +1: SPG (31.09%)
  • +2: SPG (62.51%)

The least common vehicle to feature in each Spread was:

  • -2: SPG (7.57% of all -2 Spread battles were in SPG's)***
  • -1: SPG (9.85%)
  • -1 / +1: Light (10.41%)
  • =: Light (11.38%), closely followed by Heavy (11.70%)
  • +1: Light (7.69%)
  • +2: Light (2.39%)

*The majority of SPG battles submitted were in Tier 10, meaning it was not possible to be -1 / +1, -1 or -2. So, if we ignore those spreads, the least common spread for SPG's was +1 (16.25% of all SPG battles were of +1 Spread).
**Ignoring SPG's again, the most common vehicle to feature in =, +1 and +2 Spreads were Medium (20.86%), Tank Destroyer (23.32%) and Medium (14.45%) respectively.
***And again, the least common vehicle to feature in -2 and -1 Spreads were Heavy Tanks (17.69%) and Light Tanks (17.56%) respectively.


With a focus on Tier 6 and above...

The most common vehicle class for each Tier was:

  • Tier 6: Medium (39.97% of all Tier 6 battles were in Medium Tanks)
  • Tier 7: Medium (26.26%)
  • Tier 8: Medium (41.20%)
  • Tier 9: Medium (29.93%)
  • Tier 10: SPG (73.73%)

The least common vehicle class for each Tier was:

  • Tier 6: Tank Destroyer (9.42% of all Tier 6 battles were in Tank Destroyers)
  • Tier 7: SPG (12.60%)
  • Tier 8: SPG (5.24%)
  • Tier 9: Light (8.12%)
  • Tier 10: Light (3.72%)

If we transpose the data to focus on the Tier first, we can see the most common Tier for each vehicle class:

  • Heavy: Tier 8 (33.26% of all Heavy battles were at Tier 8)
  • Medium: Tier 8 (40.26%)
  • Light: Tier 6 (22.13%)
  • Tank Destroyer: Tier 8 (33.81%)
  • SPG: Tier 10 (82.98%)

And the least common:

  • Heavy: Tier 6 (9.38% of all Heavy battles were at Tier 6)
  • Medium: Tier 7 (5.95%)
  • Light: Tier 7 (10.04%)
  • Tank Destroyer Tier 6 (5.21%)
  • SPG: Tier 7 (2.29%)

The values on a per-map basis are fairly representative of the number of total battle for each class, but we can cross-examine them to see the exceptions. These exceptions are italicised as lower than average in the most common list, and higher than average in the least common list.

A reminder: Of all 50,253 battles, Heavy Tanks accounted for 14.83%, Mediums 25.13%, Lights 11.31%, Tank Destroyers 17.34% and SPG's 31.39%.

The least common vehicle class for each map was:

  • Abbey: Heavy (14.35% of all battles on Abbey were in Heavy Tanks)
  • Airfield: Light (9.34%)
  • Berlin: SPG (12.06%)
  • Cliff: Light (9.19%)

  • Studzianki: Light (11.02%)
  • Tundra: Light (8.64%)
  • Westfield: Light (8.59%)
  • Widepark: SPG (7.49%)

If we transpose the data to focus on the Map first, we can see the most common Map for each vehicle class:
Not including Province and Widepark, as they are exclusive to low tiers, and Safe Haven as it is a new map...

  • Heavy: Mountain Pass (3.26% of all Heavy Tank battles, excluding Province, Widepark and Safe Haven, were on Mountain Pass)
  • Medium: Live Oaks (3.31%)
  • Light: Mines (5.22%)
  • Tank Destroyer: Steppes (4.10%)
  • SPG: Live Oaks (3.62%)

And the least common:

  • Heavy: Himmelsdorf (1.64% of all Heavy Tank battles, excluding Province, Widepark and Safe Haven, were on Himmelsdorf)
  • Medium: Ensk (1.54%)
  • Light: Ghost Town (1.44%)
  • Tank Destroyer: Erlenberg (1.49%)
  • SPG: Berlin (0.55%)

How do I define Range? - Click to Expand
  • The number of surviving team members minus the number of surviving enemies (e.g. A 15-5 win would have a range of 10, whereas a 7-10 defeat would have a range of -3)
  • It is possible to have a negative range in a victory (e.g. if your team captures the base to win the battle, but has less remaining vehicles than the enemy)
  • The Range has been tricky for me to define. For the purpose of this post, we are only looking at one aspect (Vehicle Class), which is why I have included it. The issue I have here is it only approaches it at a surface level: a 15-14 win has a range of 1, but so does a 3-2 win. This is why I need to approach the Range in a different way in the future, I just need to work out an efficient method. It is likely the Range will be the last area I explore before revisiting all areas and looking closer at the stats.

The most common Range for each vehicle class was:

  • Heavy: +10 (6.27% of all Heavy battles ended with a +10 Range)
  • Medium: +9 (5.93%)
  • Light: -9 (5.68%)
  • Tank Destroyer: +8 (6.16%)
  • SPG: +8 (5.89%)

The least common Range for each vehicle class was:

  • Heavy: -15 (0.25% of all Heavy battles ended with a -15 Range)
  • Medium: -15 (0.23%)
  • Light: +15 (0.13%)
  • Tank Destroyer: -15 (0.17%)
  • SPG: -15 (0.23%)

Due to how I still haven't figured out how to better portray the Range (see the drop-down above) I'm not going to explore it any further in the context of Vehicle Class. However, if we change the table to show a rank (lowest to highest frequency) we can better visualise the clusters surrounding 15-5 battles.


The most common battle duration for all vehicle classes was six minutes (23.19% of all 35,030 battles with the battle duration data lasted for six minutes). In fact, for all vehicle classes it was less likely to take a minute longer each minute after six, with the exception of fifteen minute battles. It is likely battles ending in a draw account for the increase in number of 15 minute battles, as draws are most likely to occur due to the battle timer expiring, as we found out in Part 3: Battle Duration.

The average battle duration for each vehicle was:
(Figures are decimals, not minutes:seconds. i.e. 7.15 minutes = 7 point 15 minutes, not 7 minutes and 15 seconds, which would be 7.25)

  • Heavy: 6.95 minutes
  • Medium: 6.96 minutes
  • Light: 6.75 minutes
  • Tank Destroyer: 7.15 minutes
  • SPG: 7.54 minutes

Interestingly, but unsurprisingly, SPG's were more likely to have longer battles. (53.62% of all 14 minute battles and 54.00% of all 15 minute battles were in SPG's). I say unsurprisingly, because when a player is eliminated from the battle, it is common to leave the battle so they can enter a new battle in a different vehicle. It is unlikely they will watch to the very end and be automatically returned to the garage once the win/draw/defeat condition is met. These replays do not have the battle duration data, and as SPGs tend to be some of the last vehicles to be destroyed, we can see that their battle duration will be, on average, longer.


Heavy Tanks had exactly the same number of Defeats as Victories and the greatest variation was Medium Tanks, with 180 less Defeats than Victories.

The Defeat rates for each class were:

  • Heavy: 49.45% (49.45% of all Heavy battles ended in a defeat)
  • Medium: 48.29%
  • Light: 49.15%
  • Tank Destroyer: 47.96%
  • SPG: 48.65%

The Draw rates for each class were:

  • Heavy: 1.10% (1.10% of all Heavy battles ended in a draw)
  • Medium: 1.16%
  • Light: 0.90%
  • Tank Destroyer: 1.54%
  • SPG: 1.85%

The Victory rates for each class were:

  • Heavy: 49.45% (49.45% of all Heavy battles ended in a victory)
  • Medium: 50.55%
  • Light: 49.95%
  • Tank Destroyer: 50.50%
  • SPG: 49.51%

Finally, we have the Nation of the vehicle which was featured in the replay. As I was adding the class data, I thought it would be interesting to also take a brief look at the Nation, to see if there is anything that correlates. Part 5 of the Replay Analysis will cover all areas with the focus on the Nation.

With a focus on Tier 6 and above, due to the lowest Tiers being almost exclusively Light Tanks...

The most common Nation for each Vehicle class was:

  • Heavy: U.S.S.R. (29.45% of all Tier 6 or above Heavy Tank battles were in U.S.S.R. vehicles)
  • Medium: U.S.S.R. (17.50%)
  • Light: France (35.39%)
  • Tank Destroyer: U.S.A. (25.78%)
  • SPG: U.S.A. (42.27%)

The least common Nation for each Vehicle class was:

  • Heavy: Italy (1.23% of all Tier 6 or above Heavy Tank battles were in Italian vehicles)
  • Medium: Czechoslovakia (4.23%)
  • Light: U.K. (5.18%)
  • Tank Destroyer: France (0.19%)
  • SPG: France (5.19%)

I find the least common data interesting, specifically for Heavy Tanks. Italian Heavies entered the game in update 1.11.1 at the end of January 2021, seven months before the Czechoslovakian Heavies (update 1.14, August 2021). The majority of the 66,000+ replays sent to me were sent in December 2021, not five months since 1.14, but Italian Heavies are still the least common Heavy Tank. In fact, the Czechoslovakian Heavies are the fifth least common (seventh most common) Heavy Tank to be played. The second, third and fourth least common are Poland (1.63% of all Tier 6 or above Heavy Tank battles were in Polish vehicles), Japan (2.89%) and China (4.99%) respectively.

If we transpose the data, putting the Nation first, we can see the most common vehicle class for each Nation:

  • China: Medium (38.13% of all replays, where the player was driving a Tier 6 or above Chinese Medium Tank)
  • Czechoslovakia: Medium (52.38%)
  • France: Medium (36.22%)
  • Germany: SPG (48.40%)
  • Italy: Medium (93.01%)
  • Japan: Medium (78.41%)
  • Poland: Medium (83.61%)
  • Sweden: Tank Destroyer (41.23%)
  • U.K.: SPG (39.57%)
  • U.S.A.: (63.07%)
  • U.S.S.R.: SPG (35.92%)

And the least common vehicle class for each Nation:

  • China: Tank Destroyer (12.87% of all replays, where the player was driving a Tier 6 or above Chinese Tank Destroyer)
  • Czechoslovakia: Heavy (47.62%)
  • France: Tank Destroyer (0.28%)
  • Germany: Light (6.34%)
  • Italy: Heavy (6.99%)
  • Japan: Heavy (21.59%)
  • Poland: Heavy (16.39%)
  • Sweden: Heavy (24.00%)
  • U.K.: Light (6.67%)
  • U.S.A.: Light (5.05%)
  • U.S.S.R.: Light (7.60%)

This concludes Part 4 of my Replay analysis. It has been interesting to see the many different data points, especially how SPG's were more likely to have longer battles, and Italian Heavies are the least played vehicle, even though they are eight months older than the Czechoslovakian Heavies.

Part 5 will focus on the Nation of the vehicle in focus from the replay analysed, and Part 6 will finally focus on the Range. I will have a new method to discuss the Range for Part 6.

Part 6 will conclude "phase 1" of the replay analysis. I'll likely re-publish everything in a "part 7" with an updated list of replays, but mainly to focus on the consistency when it comes to describing the data (so far it varies per part). Then, I will move on to look closer at specific aspects of replays, for example, to see if there are any correlations between the Battle Duration and class of vehicle, how having 0, 2, 4 or 6 SPG's effects different aspects of a battle, and more. The software I'm currently using won't do all of what I would like to do, so I'm hoping to work with it's author to update it to spit out more data than it does now. I do have access to an older analyser, which could be an alternative. If not, I'll seriously consider hiring someone to write the code for me, if I can afford such a job of course.

The next few months are crunch-time for university, so Part 5 will hopefully come in the next week or so, with Part 6 likely to take longer. Part 7 / the summary of "phase 1" will likely drop in the summer - this will take a considerable amount of time to put together - we're probably talking over ten thousand words alone!

Thank you for your support so far! And remember, you can still send me your replays!
