clean battlefield Browsing for links to use in a previous post I came upon some hair-raising videos produced by Textron to advertise their Sensor Fuzed Weapon, a 1,000-pound bomb containing 40 separate, self-guided warheads. One of the great things about the SFW, we are told, is that it leaves a “clean” battlefield. Isn’t that special? And what a bargain — only $360,000 for the base model! The Air Force plans to buy 5,000 of them.
