US Special Forces it strikes fear into the hearts of enemies from every corner of the planet, and they benefit from the latest technological innovations to accomplish their missions. Among them are now devices that allow them to identify any person from a distance, the special forces using lasers to accomplish everything.
US Special Forces they use heartbeats for identification because they are at least as unique as fingerprints, for example, only they can be read from a distance. The special forces use infrared lasers to detect the movements of clothing items around the chest of the targets, the measurement distances being long, the technique working through shirts or even jackets.
Special forces they are testing prototypes of devices that allow them to identify people based on heartbeats at distances of up to 200 meters, but everything takes 30 seconds. The measurement duration can be reduced, but the distance can also be increased, as the special forces soldiers need very fast identification, and at long distances, in order to carry out their missions safely.
US special forces are, for now, the only ones testing this truly innovative technology, but we could see even more for it than military applications.
"Everyone's heart is different. Like the iris or fingerprint, our unique cardiac signature can be used as a way to tell us apart. Crucially, it can be done from a distance. It's that last point that has intrigued US Special Forces. Other long-range biometric techniques include gait analysis, which identifies someone by the way he or she walks. This method was supposedly used to identify an infamous ISIS terrorist before a drone strike."
