The Tenth Sontaran Battle Fleet in the new series consists of a Command Ship and a number of capsules that can be moved into position when Battle Status is enjoined. Sontaran ships are impervious to nuclear missiles. In both the classic and new series, Sontarans are depicted using spherical or semi-spherical single-occupant spacecraft known as capsules. Each capsule is small enough to avoid detection by radar and is piloted by an individual Sontaran. "The Sontaran Stratagem" also saw the introduction of a large mothership from which the small Sontaran capsules could be seen to originate. The Doctor notes that the one ship by itself is enough to completely wipe out Earth. The Sontarans have a variety of weapons. Their distinctive weapon is a small rod with two handles and a plunger at one end, giving it a syringe style. This is so it can be held and fired using three fingers. This weapon fires a disabling beam that can temporarily render a person useless and emits an energy pulse that can repair systems like the teleport, and has appeared in every Sontaran story except "The Sontaran Experiment". When first used by Commander Linx in "The Time Warrior", it shows the ability to fire a beam which can disarm by knocking the weapon out of the wielder's hand, hypnotise, as well as cutting through wood, disabling limbs and killing. In "The Sontaran Experiment", Field Major Styre instead used a small red laser pistol which only killed (although it did not kill the Doctor, because of a small metal plate the Doctor had been keeping in his inside pocket). "The Invasion of Time" saw Commander Stor using the small rod again, but also in episode six, a Sontaran trooper uses a short black rifle-like laser to try to burn through a lock on a door inside the TARDIS. "The Two Doctors" introduced a weapon called the Meson Gun (as named in the Jim'll Fix It Sketch, "A Fix with Sontarans"), a large silver rifle with a red fuel tank in the centre which was used by Group Marshal Stike and Varl in the third episode. It seemed to be some kind of flamethrower as it fired a jet of flames very briefly. Group Marshal Stike was also seen carrying a baton. It would not be until "The Sontaran Stratagem" that General Staal would show that the baton can fire an orange beam that could stun the target.
