Firearm

A firearm, commonly known as a "gun", was a term encompassing a variety of weapons which used a projectile fired from the weapon relying on chemical explosives to propel the projectile at high velocities from the firearm. In the words of Silurian scientist K'to, "It project[ed] a small piece of metal at high speed." (TV: Doctor Who and the Silurians) They were typically used to penetrate surfaces to maim or kill and were a favoured weapon of humans.

Most firearms were ineffective against armoured races such as Daleks and Cybermen, (TV: Army of Ghosts/Doomsday) though specifically designed bullets were produced to take advantage of alien races' weaknesses (Gold in the Cybermen's case). (TV: Battlefield) Standard bullets were effective against unarmoured humanoids, such as the Ood, (TV: Planet of the Ood), Silents (TV: Day of the Moon, The Wedding of River Song) and Sontarans. (TV: The Poison Sky) Although bullets would not work on armoured races such as the Cybermen and Stingray swarm, rockets and missiles were used to defeat these species. (TV: Doomsday, Planet of the Dead)

Firearms, as a relatively primitive technology, could be neutralised by more advanced technology. For example, Sontaran soldiers employed a cordolaine field that affected metals such as copper, causing weapons using copper casings on their projectiles not to fire. (TV: The Sontaran Stratagem/The Poison Sky)

Technological improvements such as the Bastic bullet made firearms more effective, a viable weapon even against a Dalek. (TV: Revelation of the Daleks, The Parting of the Ways)

UNIT and other military personnel usually used weapons from the G36 weapons family. Officers usually carried pistols or revolvers. In future centuries future soldiers like the Anglican soldiers and soldiers in the Human-Hath War seem to carry modified P90s. One practical limit on the use of firearms was that they were usually lethal. While it was possible to use a firearm to incapacitate rather than kill, this could be done only by inflicting serious injury and pain. While there were forms of ammunition called "less than lethal" intended for incapacitation, such as rubber bullets, they still inflicted great pain, and were lethal under certain circumstances. For this reason, individuals such as the Doctor and Sarah Jane Smith often refused to use them on moral grounds (TV: The Stolen Earth, Journey's End, The End of Time (TV story), The Doctor's Daughter; TV: Invasion of the Bane) — although there were exceptions. (TV: The Seeds of Doom, The Time of Angels)

Despite their limitations, humans were known to use firearms well into the 2001st century and beyond. (TV: The Parting of the Ways, Utopia)

An appreciation of the usefulness of firearms was not limited to humanity. Upon landing on the planet Exxilon a Dalek taskforce's weapons were rendered inoperable, forcing them to replace their energy weapons with semi-automatic ballistic weapons. (TV: Death to the Daleks)
