Query: Excellent book for someone interested in military.

As a United States Marine myself I am honored to have served in the same service as Lt General Lewis Puller. Reading this book will give you an appreciation of the hardships Marines endured in the wars. Chesty Puller was an exceptional Marine, he led by example. The book examines his 37 years in the Corps. It goes into great detail and the author definitely used many resources to put this together. It's a must read. It will motivate anyone, military or civilian.
