The Sontaran baton was a device of Sontaran design.
These long black coloured batons were capable of firing an orange or red beam that was able to stun, injure or kill a target. Furthermore, they were able to repair minor damage to Sontaran technology such as the teleport pod. (TV: The Sontaran Stratagem)
Batons were carried by Group Marshal Stike, (TV: The Two Doctors) Group Marshal Nathan, (HOMEVID: A Fix with Sontarans) and General Staal of the Tenth Sontaran Battle Fleet. (TV: The Sontaran Stratagem / The Poison Sky)
Commander Steg and his troops all carried batons. On his weapons there was a concealed safety catch on the butt of the gun that prevented individuals who were not in possession of this knowledge from firing the gun. (HOMEVID: Shakedown: Return of the Sontarans)
Fleet Marshal Stentor carried a Battle Standard instead of a baton. (PROSE: Lords of the Storm)
Behind the scenes
A number of official magazines licenced by the BBC (Doctor Who DVD Files, Doctor Who Monster Invasion and Doctor Who Magazine) refer to this weapon as a "Sontaran swagger stick".
A variant of blue-armoured Sontarans, named "Carbine Sontaran", is seen wielding a baton identical to Staal's in the video game Legacy.
