Interesting article on military.com (courtesy of Engadget) about a possible replacement for the M-16 series of rifles. Made by Heckler & Koch, the modular design of the XM-8 (interchangeable barrels!) makes a perfect weapon for any modernized army. And it just plain looks futuristic, like something out of Starship Troopers. Alas, the guns in that movie do not even approach the guns from the book.
