I just ordered The Good Soldiers by David Finkel.

Fifteen months later, the soldiers returned home — forever changed. The chronicle of their tour is gripping, devastating, and deeply illuminating for anyone with an interest in human conflict. With The Good Soldiers, Pulitzer Prize-winning reporter David Finkel has produced an eternal story — not just of the Iraq War, but of all wars, for all time.
Finkel spent over a year with the American infantry battalion, the 2-16 Rangers (whose average age is 19), as they deployed from Fort Riley in Kansas to one of the most dangerous, war-ravaged areas of Baghdad. Carefully detailing the experiences of the 2-16 and its commanding officer, Lt. Col. Ralph Kauzlarich, Finkel has crafted a wartime account so visceral and so emotionally wrenching that it will leave many readers stunned.
This sounds like an amazing story! Listen to Finkel speak about The Good Soldiers here.
