A close-quarters melee weapon known by several names, including stun rod, stun stick, stun-stick, or simply stunner, the stun baton functioned by emitting a visible electrical current along its length, causing immobilization in living beings it contacted. Because of the protective nature of armor, specifically that worn by Imperial stormtroopers, these devices proved ineffective against them. The stormtrooper charger was a type of soldier that specialized in the use of stun batons. Furthermore, the rebel group Spectres utilized charging droids carrying stun batons at their secret base, Haven, for training exercises against these troopers.
