What is the author's tone in Lone Survivor: The Eyewitness Account of Operation Redwing and the Lost' by Marcus Luttrell?

The tone of this book is subjective. Lone Survivor: The Eyewitness Account of Operation Redwing and the Lost Heroes of SEAL Team 10 is a narration of the events that happened to Navy SEAL Marcus Luttrell and his team members. Even though the topic is very serious, the book is readable, moving along without becoming too depressing. The individuals highlighted are not glorified, nor are they unjustly disregarded, even in the case of the enemy.
