Steiner-Bisley 329-Series MPRS

Steiner-Bisley's 329-Series Man-Portable Rocket System (MPRS) is a dual-purpose anti-armor/anti-aircraft rocket launcher. The base system is dumb-fire only, but an optional upgrade includes a heat/RFID-seeking target lock computer. The targeting computer is a unique modification that costs 5,000 credits and takes up the Left Side upgrade slot.

If the targeting computer is attached, the weapon can lock on to targets using an Electronics roll versuss the target's maneuvering skill (Boating, Driving, or Piloting, as appropriate). Success means the targeting system has locked on to the target and can be fired. Unless the target evades the missile (requiring a maneuvering roll at -4) the missile hits automatically. A Critical Failure means the craft goes Out of Control (SWAdE 119).
