I know this is a new one, but I was approched by HarperCollins to sponsor our lan. They are promoting the book Executive Intent from the Author Dale Brown. They think that Dale's war writings would be a great match for you guys.
Click the image and take a look at the book. We will be giving away a copy of his last book Rogue Forces to each person at the LAN along with half of our attendees getting a hard back copy of his newest book! In total, around 1500 bucks in books. I am excited to see what everyone thinks of them
