Carnival of Cordite
The Carnival of Cordite is up. I esp. liked the link to this story, on how the military is considering long-overdue replacement of the 5.56 mm with something more potent. The traditional assault rifle was optimized for the 200-300 yard battles likely to take place in Europe. We're now finding, while fighting in deserts and mountains, that longer-ranged firefights are likely.
While we're on carnivals, here's the Carnival of Homeschooling.
