Military Pigs in Armor

The U.S. Army used pigs dressed in body armor and strapped them into scary-sounding "Humvee simulators" to explore the effects of various types of blasts.

After 11 months and 200 explosions, the researchers concluded body armor doesn't lead to worse head injuries, as had been feared. Also: "The research also shows that body armor protects troops' lungs and is critical to surviving blasts." Science!
