I was bored and was surfing YouTube when I came across this "Rules of Engagement" video. It's in french with subtitles, and certain specific rules (FPS related and some others) don't pertain to the rules a number of fields here have, but nonetheless it still has the proper basic ideologies of airsoft being displayed; i.e. don't be a cunt.
I did giggle a couple times during the video as well.
