Not to get too far off the topic...
A friend of mine is an under cover drug agent, and trains DEA, spec warriors, and others of that type operator. On another board we frequent, he puts up photo sequence progressions (PSPs) to share his knowledge in "real world applications of force". One of the other guys took them and made a pdf out of all the files. In my opinion, this is a real modern day fightbook, written by someone of the kind of caliber of the old "man at arms", and written for the modern fighting class.
A couple of things I noticed about it that may have some application with the old fight books:
1) There is no way to write something like this and not to assume the reader has at least
some prior knowledge of the subject when you are writing at this level and;
2) Even in modern English with photos in sequence, it is very difficult to convey dynamic action in writing.
It is well worth reading for real world instruction from and for people that have been there and done that for real.
