The U.S. Special Operations Forces will soon be able to see through walls
Playing games and dealing with the villains and vampires popping out from behind walls and bookcases is the theme for horror movies, but for U.S. special operation forces, hidden compartments are not entertainment. In the world of special forces, they are representing obstacles to a successful mission. The mission objective is to capture bad guys or seize documents and weapons. And on a house raid in hostile territory, there isn’t a lot of time to go tapping on walls to find a hidden stash.
That’s why U.S. Special Operations Command (SOCOM) works on a detector that can quickly spot where the loot is hidden. The goal of the research project is to develop a handheld device that can detect hidden chambers in an average-sized room (168 square feet) and at a range of about 6.5 feet during sensitive site exploitation, or SSE, operations.
