Porcupine C-RAM.

via DefesaGlobal.

Finmeccanica´s Oto Melara SpA has developed the Porcupine (or Porcospino) counter rocket, artillery, and mortar (C-RAM) protected weapon system.

The ground based weapon system is intended to serve as a defensive system for land based military facilities or critical infrastructures against destroy incoming artillery, rockets and mortar rounds in the air before they hit their ground targets, or simply provide early warning capability.

Each remotely controlled firing unit comprises the supporting mount along its protected covers, a General Dynamics Armament & Technical Products (GD ATP) M61A1 Gatling 20mm six-barrel externally powered lightweight cannon, the ammunition handling and feeding system, the drive system, the power management unit, stabilized optronic day/night infra-red tracking system for target engagement and as well as associated mechanical components.

I don't know how effective this system would be if it were mounted on the Marine Personnel Carrier, but if it could be made to work then it should be a winner.

We can expect even insurgents to start getting their hands on rockets...and some groups will get advanced weapons.  I wouldn't be surprised to see them get advanced rockets.  This system or others like it might save a Command Post or two in those vaunted humanitarian missions HQMC is so jazzed about doing.
