What is the author's style in Rogue Warrior by Richard Marcinko?

The perspective of the book is that of an autobiography of an intensely combative military man, Richard Marcinko. Richard is extremely hard-line as a person and in the military. He deliberately projects a so-called macho personality of a man who from an early age pursues fighting and adventure, and from adolescence, women. In his home there is little interest in academics. Richard quickly learns to make money and pursue female conquests.
