Back when I was a little kid, my little group of friends would “play army” and we had set up some hand signals for silent communications. Worked well for a bunch of 8-10 year old kids who learned it from the movies haha.
It’s something we should all take a look at and get a basic idea of how to set up our own for our people/group. Never know when it might come in handy.
