In the Company of Soldiers: A Chronicle of Combat by Rick Atkinson
Atkinson is the best-selling author of the WWII in Europe trilogy, An Army at Dawn, The Day of Battle, and The Guns at Last Light. During the invasion of Iraq, he was embedded with the 101srt Airbourne division, specifically with the CO, MGen David Petraeus. This put him close to both command and the action. His take on Petraeus is very interesting. For those who want to know more about how it feels at the sharp end, I recommend this book.
