I'd be interested. Mainly because I'm also working on my own book that cover this type of things.
I don't have your experience of the real world, but I have a lot of expenrience on the field.
I bought a book that is very much like what you are doing.
Light Infantry Tactics: For Small Teams: Amazon.ca: Christopher E. Larsen: Books
It was very well made and helpfull. Well illustrated and to the point.
I want to make something even more specialised toward airsoft, like I did for snipers.
