The M78 PIG (Phased-plasma Infantry Gun) is a man-portable anti-armor weapon. Weighing 15.2 kg in its entirety, the PIG consists of two parts: the gun and its power pack. The M78 is a 15 mW phased plasma system firing vaporized Cadmium Telluride pellets from a 30 round feed. The fast-discharge system powering the gun's laser and magnetic coil is fed from a 4 mW hydrogen fuel cell in the power pack. The firing cycle takes 3 seconds, most of which time is taken up by the powering up of the discharge generator. The penetrating power of the system is considerable, and it is claimed to be able to breach the flank armor of a heavy tank at 1,000 m.

“Meet mah friend PIG. He’s big an’ fat an’ a bitch to carry, an’ he don’ look like much y’know. But `f I point him at yo’ an’ pull this trigger, then he’ll blow a hole through yo’ big `nuff to drive a panzer thru’. No use hiding in an APC either: Mister PIG say `snuff’ an’ your armoured baby carriage suddenly acquire some new air conditioning, stak? So, say `hello’ to Mister PIG befo’ he get upset. Oink, oink.”
