You've probably already seen Michael Yon's latest dispatch, "Gates of Fire." If you haven't read it, do so. Wow. One of the best lines: "I was going to run into the shop and shoot every man with a gun. And I was scared to death."
LTC Kurilla was wounded in the firefight Yon describes. He is currently doing well, but no word on when/if he'll return. Here is one of the speeches Kurilla gave at a memorial for some of his soldiers. (HT: Blackfive)
Where does the courage exemplified by Yon and Kurilla come from? It is an amazing thing.
