Shoot to Protect describes a new anti-RPG device:
In another few years, Hummers’ roofs could be covered with a dozen tubes, each filled with a foot-long mini-rocket called the FCLAS — short for Full Spectrum Active Protection Close-In Shield.Every FCLAS would have a pair of radio-frequency sensors inside. One in the nose would detect incoming RPGs and fire off a counterstrike. A second sensor, in the rocket’s side, would go off when the RPG comes within range. The FCLAS would then detonate, letting loose a hail of explosive fragments, destroying the grenade in the process. The whole attack and response would take no more than a few seconds.
I think I can see a downside:
“And we have to make sure that if someone throws a rock, or a bird flies by, that it doesn’t go off.”
