What is the author's style in The Forgotten Soldier by Guy Sajer?

The Forgotten Soldier is written from the first-person, subjective point of view common to most autobiographies. The author does not attempt to provide a precise history, or even chronology, but rather focuses on his subjective experiences during the period described. Chronologically, the book is organized in a typical fashion but numerous entries return to time periods already covered in summary and explore them in greater detail.
