Stun rod

A Stun Rod is a device used to incapacitate enemies. It is charged with a million and a half volts, enough to knock someone on the receiving end out cold. The Militaires Sans Frontieres often used these devices in the event that they go into battle, and apparently mastering the use of one is part of the training regiment, as the tutorial has the soldiers training in the use of Stun Rods (although they used mock stun rods during training sessions, requiring the partner to act as if it's the real deal.)
