If you haven't heard of Wikileaks' recent release of 91,000 classified reports about the war in Afghanistan covering 2004 to 2010, you could start with the links here. I've put the raw data in a Fusion Table to look at it from different angles. The first result is this map showing where the war is taking place. More black means more war. The data also shows that for every 100 enemies killed or detained, about 150 civilians/friendlies were killed or wounded. You can browse the complete dataset in a Google Fusion Table. (The "war logs" at the Guardian only cover about 18% of all reports.)
