Using technical data provided by the Axis and their own line of research, Imperial Japanese scientists have created devices that generate a field capable of temporarily phasing objects or people out of sync with the world around them. The land-based military implementation of this research – the Ghost Attack Squads – has proven adept at surprising Allied forces, literally appearing from the shadows to attack from unlikely directions or through the heaviest terrain. Armed with Shiboru compression rifles, a squad of ambushing Ghost soldiers can lay down a significant weight of fire before vanishing back into dense terrain, making attempts at pursuit futile.
