Yes, it's true and was
confirmed by the official media sources like TASS for example.
But as usual, the devil is in the details. Some TG channels claim that this is the first time something like this is going to happen.
But it looks like it isn't the first time for such a "massive emergency drill".
Here we can read that it also happened on 6th of October 2021. There was no such drill in 2022.
Here's an official press release on Ministry of Emergencies and Disaster Relief site dated 6th of October 2021.
Another claim is that this time it's going to be special with an emphasis on the possibility of the nuclear or chemical fallout, or large amount of casualties. But this is also not the first time, and it was part of the drill also back in 2021. Here's a photographic evidence from
this post in TG.

It doesn't mean that there is no real reason for such trainings, but we should be careful about looking for "synchronicities" or strangeness without doing the necessary research that will put things in perspective. This way we will also have a more clear idea.
Having said that, apparently various astrologers talk about October being a particularly intense month. The most intense moth of the year. So we will see how it will actually manifest in the world.
Svetlana Dragan also predits a very challenging time for Russia. Here's a translation of her analysis for October on her TG channel.
It was written in the end of June this year. Will see if and how it will actually happen, because right now it's hard to see that the situation will be that dire only in 3 weeks. Maybe as usual the dates will shift.
So it's quite possible that there is a good and prudent reason for training. Maybe not for now, but for later.
