If you have run into Es Gratis in Rainbow Six Siege and moved on without quite understanding it, this is the explanation.

Short answer

Short version — it is exactly what it looks like, and the confusion comes from a similarly named thing nearby.

  • Ask what it is for before asking how to get it.
  • Ignore the myth attached to it; it has never held up.
  • Region and platform change more than people expect, so confirm both.

Siege rewards knowing the building more than knowing the gun, which is why map knowledge outranks aim here. The wiki entry is thorough and buries the actually useful part six paragraphs down. Community shorthand around it has drifted far enough from the original meaning to cause arguments.

What it is

Rainbow Six Siege is not shy about hiding useful information two menus deep, so some of this is simply knowing where to look. Two similarly named things exist, and mixing them up explains a lot of contradictory advice. It shows up in more places than its introduction suggests, once you know to look. It helps to understand why a step exists, because then you can adapt it when your situation is slightly different.

Its role has changed across updates, so older discussion describes something slightly different. It is more consequential in the late game than the early one, which is why first impressions mislead. There is no hidden trick here that the game is keeping from you.

How it connects to the rest of Rainbow Six Siege

Knowing this does not make you better at Rainbow Six Siege, but it does make the rest of it legible. The in-game description is technically accurate and practically useless. The awkward part is rarely the step itself, it is knowing which step comes first.

  • Expect its role to have shifted at least once across updates.
  • Read the in-game description once, then ignore it.
  • Prefer the in-game option over an external tool when both exist.
  • It rewards attention rather than preparation.

Where you encounter it

It is the kind of thing veterans forget they ever had to learn. It became noticeably more relevant after a change the patch notes barely mentioned. The developers have changed their mind about this at least once, which explains the older advice. The name is descriptive if you already know what it does, and opaque if you do not.

There is a persistent myth attached to it that has never been true in any version. A single check up front replaces a lot of guessing later. Whether it is worth going out of your way for depends entirely on how you are playing.

Common misunderstandings

If you only remember one thing about it, remember where it appears. If a step reads as obvious, do it anyway — the obvious ones are the ones people skip and then wonder about. Early impressions of it are usually wrong in the same specific way.

Its practical value is narrow and real, rather than broad and theoretical. Anything that behaves differently on console than on PC is flagged where it matters. Most guides mention it in passing and none of them stop to define it.

What it changes in practice

It appears in supplementary material in more detail than it does in the game itself. There is usually a fast way and a reliable way, and it is worth knowing which one you are choosing. It rewards understanding rather than grinding, which is unusual for Rainbow Six Siege.

Where people go wrong

  • Skipping the prerequisite because it looked optional in someone else's summary.
  • Grinding a method that was patched months ago because a thread still ranks well.
  • Rushing the last step, which is usually the one with the actual requirement in it.
  • Assuming a guide from an older season still describes the current version.

Siege FAQ

What if none of this works for me?

Then something in your setup differs from the assumption — version, region or platform. Check those three before anything else.

Do I need any mods or third-party tools for this?

No. Everything described here works with the base game on any supported platform.

Where can I read more?

The official material covers it in more depth than the game does, and considerably more reliably than aggregated fan pages.

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.

That is the whole of it — if something here stops matching Rainbow Six Siege, the game changed, not the method.
