Sua Sponte: The Forging of a Modern American Ranger by Dick Couch. Still reading about the elite Army units. This book is new and focuses on the selection and training. It helps an outsider like myself understand more about how the U.S. Army is more complex than might initially appear.
Chosen Soldier: The Making of a Special Forces Warrior by Dick Couch. Very similar to Sua Sponte. I preferred Sua Sponte because it is more recent. This book about the Special Forces helps one understand the difference between two elite Army units. They may choose soldiers from the same pool, but their goals are quite different. I think many people do not understand the role special forces have and this book, along with The Only Thing Worth Dying For: How Eleven Green Berets Fought for a New Afghanistan (P.S.) give a clearer picture.
Extra Virginity: The Sublime and Scandalous World of Olive Oil by Tom Mueller — I learned so much about the olive oil industry from this book. It was a delight to read and led me down to a new olive oil store just to better understand and to sample what is considered good quality olive oil.
