Recently I finished writing a complete Airsoft Tactics Manual that I've been spreading via the internet. It is heavily researched and rewritten in an easy to understand way for both beginners and experienced players. It goes over everything an airsofter would want to know regarding tactics to help improve their or their teams game.
As I wanted as many people as possible to be able to get it and read it I've put it online as Pay what you want.
If you'd like to check it out, you can find it at the URL below.
