“…SOCOM is asking for proposals that’d “reduce the warfighter’s facial signature” in marine environments, to minimize their risk of heat-based detection by infrared sensors or motion-based spotting via electro-optical surveillance.

Sounds crazy, but they just might have a shot. In 2008, the Army Military Research Office boasted that they were a mere two or three years away from developing metamaterials that could deflect light to conceal a given object.

Since then, experts at various institutions have made impressive progress. Researchers from the University of Texas at Dallas have shown off an invisibility cloak that harnesses the “mirage effect,” defense company BAE Systems has developed a system that renders vehicles invisible to the entire infrared spectrum and physicists from St. Andrews University broke new ground with a meta-material that comes even closer to all-out undetectability.”

“The U.S. military can see you breathing on the other side of that wall. It can even see your heartbeat racing while you crouch behind the door. But if you think running farther away or hiding in a crowd will make you invisible to the Defense Department’s sensors, you might be in for a surprise. The Pentagon’s geeks are looking to tweak their life-form finder so they can spot your tell-tale heart no matter what you do.

Darpa, the Pentagon’s mad-science shop, announced last week that it’s looking to improve on technologies that sniff out biometric signatures like heartbeats from behind walls. Dubbed “Biometrics-at-a-distance,” the program seeks to build sensors that can remotely identify humans from farther away and tell them apart in a crowd.”

“Twice in the span of a month, the Taliban has unleashed human waves on one of the U.S. Army’s most isolated Afghan outposts. Twice, the American soldiers guarding the tiny fort have beat back the attackers, killing scores of extremists while suffering no losses of their own.

The U.S. troops’ skill, and luck, have been remarkable. They’re going to need both, as more large-scale attacks seem likely.

…Once the shooting starts, the Taliban know they probably have only a few minutes before the Apache helicopters and Air Force jet fighters arrive overhead and unleash Hell.”
