Fellow tankers,

After diving deep into how modern MBTs are represented in War Thunder, one recurring issue stands out: the way main gun dispersion is modelled.
It indeed seems modern MBTs currently have accuracy levels of early cold war MBTs.

Let’s take the Leclerc as a concrete example, which is a MBT built around a doctrine relying on precision of engagements.

For instance, multiple documents mandates ≤ 0.1 mils spread for the CN120-26 on the move and ≤ 0.08 mils spread while being still.
This level of accuracy is a fundamental design choice from GIAT (now NEXTER) engineers as the Leclerc was designed to fight against a numerically greater force. In this context, missing shots was simply not an option for engineers of the Leclerc program.

  • Stéphane Ferrard and Gérard Turbé, The Leclerc System (Saint-Germain-du-Puy: l’Imprimerie Tardy Quercy S.A, 1992). S. Ferrard is known for his knowledge when it comes to French weapon and armour: “[…] All these figures apply for a cross country speed of 36 km/h and for practical firing ranges varying between 300-4,000m with an H+L of 60 cm […]”;

  • Pierre Chiquet, La Gabegie (Paris: Éditions Albin Michel, 1997). P. Chiquet was president of Giat Industries from 1990 to 1995: “[…] The Leclerc shoots at a target 4,000 meters away, with an accuracy of just a few dozen centimetres […]”;

However, in-game testing paints a whole different picture: rigorous testing shows an average 0.48 mils spread, a 4.8x deviation from the historical 0.1 mils.

Actually, since we are talking about spread, and thus area, the difference is much more than that.

→ 0.1 mils: 0.126 m² at 2000m
→ 0.48 mils: 2.89 m² at 2000m

We end up with an average spread in the form of a 2,89 m² circle instead of a 0,126 m² circle. 0,126 / 2,89 = 23,04.

It means Leclercs have a whopping 23,04x times worse accuracy than they should.

Here is a visual representation of the issue, the red circle being the current spread and the blue circle being the historically accurate spread:

It’s not only a numbers issue, but also a gameplay issue since at 1,500m, this reduces hit probability against a 1.35m target (L.3-33) from ~92% (expected) to ~61% (tested).

We can see that means sometimes completely missing your target as shown in the screenshot below.

For a tank designed around precision, that’s not a minor discrepancy, it’s a fundamental historical misrepresentation.

I invite players to check if the same applies to other modern MBTs: I wouldn’t be surprised to learn the same goes for Leopard 2s or Abrams.

If the goal is to offer historically grounded and competitive MBT gameplay, this is something worth looking into. Not just for the Leclerc, but for modern NATO designs in general.

For these reasons, I urge Gaijin to adjust spread to 0.1 mils per technical manuals and review the gun’s behavior against historical documentation and investigate for other MBTs.

Having early cold war MBTs spread on modern MBTs is not a good look for a game that prides itself in its historical representation of vehicles.

Let’s ensure Gaijin sees this. Our top tier flagship MBTs deserves their documented accuracy.

Happy hunting!

Danke.
Und das Video ist cool.

Sie sollten wirklich die Streuung der Waffe verbessern. Beim Abrams sollte ein T-80UD aus 1562 m Entfernung nicht viel danebengehen.

They really should fix the gun dispersion Shooting a T-80UD 1562m away should not miss a lot in abrams

Hell yeah!

Was this test done using an aced crew with spaded tank?

I appreciate the answer.
You have my support in this regard then.

It’s unbelievable that we have to put a vote on something that developers should be doing within the first minute of developing the game.

they ignore all documents proving this mechanics broken. We need to let gaijin know all tanks need historical spread rework!

I support your idea and I’m impressed with the effort to research and present the facts here. Though, moving this further will require even more work, one being from Gaijin, will they implement?

Prior to this the community—we all live in houses in the same garden, some players say the flowers in their exclusive garden’s part are more beautiful, but others say otherwise.

What I mean is, will the community, specially ground battles players work together for the good of the game showing enough support and voice to force Gaijin to change something? In my opinion that’s the most hard part of any major change in this game.

I personally think this is very important to implement for top tier tanks. The current META heavily favors well armored MBTs at range since the current spread of say the Leclerc makes it very unreliable at hitting weak spots of Leo 2A5 (breach) and T series (driver port/breach) in long range map. IRL the superior FCS system of the Leclerc compared to Soviet tanks was to allow a Leclerc to engage those tanks beyond their detection/firing range more reliably than they could, but what we see happening in game is the opposite. And the lack of armor of the Leclerc makes it easy to destroy at any range.

The worst about all this is that, for each MBT, we are only a value away from each vehicle’s code being historically accurate …

They’re made inaccurate on purpose to necessitate “adjustment of fire” and “elevation mechanic” module grind

And they’re accounted for the sub 1km engagements. Also I think gaijin makes accuracy based on caliber so KV-2 has less spread than long 50mm guns and 17 pounder

Testing was made with Ace crew and Spaded vehicle (all modifications researched) as provided here: Main gun spread of modern MBTs should be modelled more accurately - #7 by totolescargo
