They're not. Read the preface, while the intended audience is all soldiers, the manual is geared towards trainers. The value isn't in the content of the publication (hence why it's public), it's in the training that soldiers undergo to make the information 1st-hand nature. Example--you can read about the OODA loop. Reading about it doesn't make you good at using it. That takes training, and the Army has specific exercises that helps a baseline soldier know the fundamentals. Like with nearly all skills, start with first principles, ingrain them with drills and repetation, then build advanced skills based on those fundamentals.
