A sapper (also called an EMP clamp) is a type of destructive device meant to be planted on another device, android, etc. in order to produce directed and repeated EMP pulses into it in order to disable or destroy it. Most sappers contain some means of triggering it and one or more short prongs that can breach through a device's EMP shielding. When placed on an android, the part of their body that the sapper is placed on will be completely disabled until it is taken off or the sapper runs out of power. If the sapper is placed on their limb, that limb will be disabled, and if it is placed on their torso they will be paralyzed. If placed near their core, it may knock them unconscious.
