Porcupine RPG countermeasure
assembly, under development at Northrop Grumman, integrates
a pack of interceptors (4 or 8) mounted on remotely controlled
weapon station side by side with an XM307 crew served weapon.
These countermeasures utilize modified LAW rockets, which are
aimed and programmed to explode near the incoming rocket, thus
neutralizing its warhead at a stand-off distance form the protected
vehicle.
