This is the first of a series of books that will try to explain the essentials of combat. It is intended for use by airsoft & paintball players, and also for those who simply wish to gain insight on how certain tactical procedures are performed. The book is fundamentally based on REAL techniques and tactics that are used around the world, and are therefore procedures that are similar to those used in various army and military units. Due to this the book may be of interest both to fans of the war-games as well as those interested in military activities. The book uses language that may not be to every reader's liking, but it is intended to provide understanding. There is regular use of the words "weapon", "enemy", "opponent". I hope this doesn't limit enjoyment for those who will find the content useful and of interest. Due to the author's ethics, these books will never contain any information or sensitive material that could be misused. For this reason there will be no mention or reference made to the manufacturing of explosives or weapons, or procedures that could be used against those that protect us from violence and terrorist acts. Our aim is to encourage those who wish to learn more about these concepts, update those who already have some knowledge of them and in particular support and educate Airsoft and Paintball players by sharing the information we have.
