Ask about B2 in War Thunder and you get five confident answers, three of which describe an older version.

Short answer

It is worth understanding once properly, because a lot of other things in War Thunder refer back to it.

  • Ask what it is for before asking how to get it.
  • Read the in-game description once, then ignore it.
  • Region and platform change more than people expect, so confirm both.

War Thunder models more of the vehicle than it tells you about, and the grind punishes guessing. Most guides mention it in passing and none of them stop to define it. Whether it is worth going out of your way for depends entirely on how you are playing.

What it is

There is usually a fast way and a reliable way, and it is worth knowing which one you are choosing. It became noticeably more relevant after a change the patch notes barely mentioned. It appears in supplementary material in more detail than it does in the game itself. What follows assumes you are on a current install and have not modified it.

If you only remember one thing about it, remember where it appears. The wiki entry is thorough and buries the actually useful part six paragraphs down. The community wisdom on this is roughly half right, and the half that is wrong costs the most time.

What it changes in practice

Early impressions of it are usually wrong in the same specific way. Two similarly named things exist, and mixing them up explains a lot of contradictory advice. None of this needs a paid tool, a third-party launcher or an account on a site you have never heard of.

  • Treat wiki trivia sections as trivia rather than mechanics.
  • Note where it first appears, so you can go back if you need to.
  • Prefer the in-game option over an external tool when both exist.
  • Check which version of War Thunder any discussion of it is describing.
  • Do not build a plan around it before you have seen it work.
  • Write down what you changed, so you can undo exactly one thing if it goes sideways.

Where you encounter it

It rewards understanding rather than grinding, which is unusual for War Thunder. The name is descriptive if you already know what it does, and opaque if you do not. If you are coming to this after a long break, the terminology has probably moved on. It shows up in more places than its introduction suggests, once you know to look.

It is more consequential in the late game than the early one, which is why first impressions mislead. Treat anything stated without a version number as provisional. The game introduces it quickly and assumes you picked it up, which is where the confusion starts.

What to do once you have it

Knowing this does not make you better at War Thunder, but it does make the rest of it legible. The developers have changed their mind about this at least once, which explains the older advice. Community shorthand around it has drifted far enough from the original meaning to cause arguments.

There is a persistent myth attached to it that has never been true in any version. The awkward part is rarely the step itself, it is knowing which step comes first. Its practical value is narrow and real, rather than broad and theoretical.

How it connects to the rest of War Thunder

Its role has changed across updates, so older discussion describes something slightly different. A single check up front replaces a lot of guessing later. The in-game description is technically accurate and practically useless.

Where people go wrong

  • Ignoring the platform-specific note and then wondering why the steps do not line up.
  • Downloading a helper tool for something the game already does in its own menu.
  • Trusting a video thumbnail that promises a result the video never actually shows.

War Thunder FAQ

Why do other guides describe this differently?

Most were written for an earlier version and never revisited. Compare the steps against what your build actually shows.

Why do people disagree about it?

Usually because they are describing different versions, and occasionally because a similarly named thing exists alongside it.

Does this work the same on console and PC?

The logic is identical. Menu paths and button prompts differ, and any real difference is flagged above.

Is this still accurate after the latest War Thunder update?

The method is; individual numbers may not be. If a value on your screen differs, trust the screen and keep the sequence.

Come back to the caveats list if it does not work first time — the answer is almost always in there.
