From Michael Yon:
New Year's Eve, 2009
On this small base surrounded by a mixture of enemy and friendly territory, a memorial has been erected just next to the Chapel. Inside the tepee are 21 photos of 21 soldiers killed during the first months of a year-long tour of duty. The fallen will belong forever to the honor rolls of the 1-17th Infantry Battalion, 5th Brigade, 2nd Infantry Division, and they will join the sacred list of names of those who have given their lives in service of the United States of America.
Update: Greyhawk has two posts up with the political backstory on this unit's deployment and some of what's happened since they've been in country.
