It's a big claim, I don't believe it. As other posters mentioned, no other sources confirming.

The video he doesn't even say anything specific like this.

Sounds like he mentioned the name Feulmich, or however I spell it, the Corona committee guy, who just separated from them, is this perhaps from one of their exercises, mock things they do?

I sure hope no one is sharing this out to normies without further validation and vetting, will look silly otherwise.
