Youtube video about a NATO wargame

An Australian YouTuber got invited to a NATO wargame and made this very interesting video about it.

The section that starts at 3m30s (10 minutes long) discusses the military history of wargaming which I found fascinating.

The rest of it is also well worth a watch.

It's not new (it sat in my watch later list for a month since it's 65 minutes long) so apologies if you've already seen it.
