A small group of Army Rangers—the elite unit of ground troops—were testing out the beta version of a “see through walls” (STW) sensor at Eiler Hall, an old maintenance facility converted into a training site. One soldier pointed the sensor, housed inside a big, bright-orange suitcase, directly at the target: a windowless building that might contain the enemy. Several yards behind him, another took a reading off a laptop.
On the screen: a simple graph charting time and distance. A single red dot moved down the grid. Movement behind the wall!"
Up until now, the only way to see through the wall was to blow a hole in it and stick your head in,” says Maj. Bill Kembley, our tour guide for the training exercise.

It will be at least a couple years before the Army actually uses this STW technology, and by then it will look a lot different. The sensor, for instance will be the size of a Palm Pilot, not a 14-pound suitcase. And it won’t be orange.
