Yesterday there was a change of command between top generals in Iraq…GEN David Petraeus passed command to GEN Ray Odierno. As I was reading about what was said during that ceremony, my mind wandered back to the numerous images I've had sent my way since 2003 when Operation Iraqi Freedom began. This has been a very long war and many things have changed over time, some for the better, some for the worse. And, we've still got a ways to go. Here are some of those images with no captions or photo credit.
