Rheon carbine

Rheon carbines, also known as swagger sticks, (AUDIO: Starlight Robbery, PROSE: The Two Doctors, Lords of the Storm) were wand-like Sontaran weapons of choice. (PROSE: Lords of the Storm)

Characteristics and functionality
While consistently wand-like in shape, (TV: The Time Warrior, The Two Doctors, The Sontaran Stratagem, et al.) other details could vary in appearance, such as some models looking like long, clear tubes with silver caps, (HOMEVID: A Fix with Sontarans) complete with "bulbous flash-eliminators" (PROSE: The Two Doctors) Other models were black, with one of the ends having a larger ball-like object on it than the other. (TV: The Sontaran Stratagem/The Poison Sky)

Rheon carbines fired pockets of charged (PROSE: Lords of the Storm) rheon particles (PROSE: A Soldier's Education) orange or red in colour, capable of stuning, injuring or killing a target, (HOMEVID: Shakedown: Return of the Sontarans, TV: The Sontaran Stratagem/The Poison Sky) even through armour. (PROSE: Lords of the Storm, Shakedown) Furthermore, they were able to repair minor damage to Sontaran technology such as the teleport pod. (TV: The Sontaran Stratagem) There was a concealed safety catch on the butt of the weapon that prevented individuals who were not in possession of this knowledge from firing it; (HOMEVID: Shakedown: Return of the Sontarans) the safety catch also prevented the carbine from being accidentally discharged. The Rutan Host could resist the effects of a single weapon's fire for a certain amount of time, but multiple bursts would defeat the Rutan's defences. (PROSE: Lords of the Storm, Shakedown)

History
The weapon was carried by Group Marshal Stike, (TV: The Two Doctors) Group Marshal Nathan, (HOMEVID: A Fix with Sontarans) Commander Steg and his troops, (HOMEVID: Shakedown: Return of the Sontarans) and General Staal of the Tenth Sontaran Battle Fleet. (TV: The Sontaran Stratagem / The Poison Sky) Fleet Marshal Stentor carried a Battle Standard instead of a baton, however. (PROSE: Lords of the Storm)

Behind the scenes
A variant of blue-armoured Sontarans, named "Carbine Sontaran", is seen wielding a baton identical to Staal's in the video game Legacy.
