->''"The second rule for surviving Zombieland: The Double Tap. In those moments when you're not sure if the undead are really dead-dead, don't get all stingy with your bullets..."''
-->--'''Columbus''', ''Film/{{Zombieland}}''

An amateur only shoots once. A ''professional'' always shoots twice. A subtrope of BoomHeadshot, this is the difference between a sniper and a more up close and personal silenced pistol assassin. [[MakeSureHesDead Better safe than sorry, after all]]. The Double Tap seems like [[ThereIsNoKillLikeOverKill overkill]], but it's actually a heavy example of [[CombatPragmatist pragmatism]]. People surviving a headshot are rare, [[TisOnlyABulletInTheBrain but they happen]], and there's nothing like someone surviving a headshot to ruin your carefully laid plans. Similarly, there have been occasions where despite shots to the chest, people have continued to be coherent and capable of retaliation for some time there after. However, two to the head is much more likely to be certain. Some training methods insist on at least one shot to the torso and two to the head (still not overkill, really: even if you survived two shots to the head, a fatal shot to the heart means that you now have ''two'' life-threatening injuries to recover from, and most people die from either one), but two to the head tend to be just as effective... [[VideoGame/FalloutNewVegas Usually.]]

Contrast OnceIsNotEnough. Compare and contrast KickThemWhileTheyAreDown, which is similar in confirming a kill but usually is seen as having more negative connotations.

[[folder: Anime and Manga ]]

* Batou double taps a surprised Special Forces fighter near the end of ''GhostInTheShellStandAloneComplex''.
** In a stand alone episode in the middle, he quickdraws and neatly double taps three targets in a row before they can get a shot off.
* In ''{{Change 123}}'', Fujiko was trained by her father to shoot every target twice; once in the head and once in the heart.
* Referenced by name and perforned by [[{{Otaku}} Gun nut Kohta Hirano]] in ''HighSchoolOfTheDead''. He doesn't even wait for the first bullet to finish [[BoomHeadshot its faithful journey]] before firing the second.
* When Vanessa learns to shoot in ''Anime/{{Madlax}}'', the eponymous heroine explains that double-tapping is more efficient than single shots.
* Specifically emphasized by Tenma's trainer in ''{{Anime/Monster}}''.

[[folder: Film ]]

* ''Film/{{Zombieland}}'' has this as Rule #2 for surviving the ZombieApocalypse. Despite the zombies in the movie being of the [[TechnicallyLivingZombie Technically Living]] variety, the characters frequently make sure to [[RemovingTheHeadOrDestroyingTheBrain Remove The Head Or Destroy The Brain]]. This is seen performed with guns, [[DropTheHammer giant mallets]], and even a [[CarFu car]] at one point.
* Near the beginning of ''BeverlyHillsCop'' Mikey Tandino is executed by two shots in the back of the head. Axel Foley's captain notes that it was a professional hit.
* Seems to be favored by Keyser Soze in ''The Usual Suspects''; although he doesn't make the connection as he says it, Kujan reveals that this is also how [[spoiler: Edie Fineran]] was killed.
* ''Film/TheGodfather'': When Michael goes to kill Solozzo and his bodyguard [[DirtyCop McCluskey]] at a meeting, Sonny instructs him "Two shots in the head apiece."
* There's a Hong Kong action movie ''named'' Double Tap, about a series of murders where the victim always had two bullet holes in the head, ''[[ImprobableAimingSkills close enough to form an '8'.]]''
* In ''TheBoondockSaints'', a Boston detective is able to distinguish the target of a hit from the assorted dead mooks because he was offed this way:
-->'''Duffy:''' He was the only one done right. Double tap, back of the head.
* Vincent from ''{{Collateral}}'' shoots the chest twice and the head once (the Mozambique Drill, mentioned below in the RealLife section).
* The robbers in ''{{Film/Heat}}'' shoot their victims twice in the chest and then once in the head. Detective Vincent Hanna notes this as one of several things that marks them out as serious professionals.
* MorganFreeman's character Charlie in ''NurseBetty'' lives by this:
-->''"Two in the head, you know they're dead."''
* ''Film/PacificRim'': Taken to ThereIsNoKillLikeOverkill levels. With a plasma cannon. Into the chest of a {{Kaiju}}. Justified because [[spoiler: his failing to do so earlier cost him his brother Yancy.]]
-->'''Raleigh''': Let's check for a pulse. ''[fires plasma cannon into its chest until most of the internal organs are ash]'' No pulse.
* AntiHero Danny Archer from ''Film/BloodDiamond'', who is former South African special forces turned mercenary, does this regularly. [[http://www.youtube.com/watch?v=BstunZN_e7g This]] is probably the most notable example.
* Film/PansLabyrinth: Whenever a battle is won, the winning side always takes the time to shoot the fallen enemies in the head, be they rebels or fascists. Vidal even has a moment where he points his gun at a soldier who's been shot in the trachea and he can only weakly bat away his gun, Vidal resets the position and it happens back and forth until he executes him.

[[folder: Literature ]]

* [[ActionGirl Murphy]] mentions (and does) this several times over the course of ''Literature/TheDresdenFiles''.
* In the book 'Vengeance' (the basis for the film ''Munich''), the author recounts his shooting lessons during Mossad training. The instructor told the class to always fire two shots at a time. "Always BANG BANG...Never just god-damned BANG!"
* John Kelly of Creator/TomClancy's ''Literature/JackRyan'' series uses this technique extensively in ''Without Remorse'', largely because of his SOG[=/=]SEAL training, with his Colt .45. When he configures it as a .22 with a home-built suppressor, his especial reliance on the double-tap headshot is mentioned as particularly necessary given the .22's relative weakness--and as an indicator to the investigating policemen that they're dealing with an experienced professional. When he switches it over to .45 configuration, he changes to two in the chest, one in the head, a sign that he's discarding subtlety for the last push.
* In ''Literature/ArtemisFowl'', [[BattleButler Butler's]] preferred technique is two to the chest, three between the eyes.
* In SergeyLukyanenko's ''Literature/AutumnVisits'', one of the characters is a contract killer. When another character gets thrown from a roof to be ImpaledWithExtremePrejudice, he follows up with a headshot, just to be sure. Especially, since the killed character is [[spoiler:not entirely human]].

[[folder: Live Action TV ]]

* The Mozambique Drill (see RealLife) has also been used in ''Series/{{Dexter}}''.
* The Mozambique Drill is also excellently demonstrated by Jim Zubiena in the MiamiVice episode "Calderon's return."
* In ''Series/{{Revenge}}'' this is used by [[spoiler: Takeda]] to execute a wounded [[spoiler: Tyler]] on the beach. Also used by [[spoiler: Daniel]], who shoots Emily twice in the stomach and lets her fall overboard during her honeymoon cruise.
* In ''Series/TheWire'', this tends to be the preferred method for the enforcers of the notorious Stansfield drug empire. [[TheDragon Chris Partlow]] tends to execute with two shots to the head, and new soldiers are trained to either shoot for the head if they're at point blank range, or to disable by shooting under a potential BulletProofVest and then finish with a head shot. That said, they're sometimes sloppy about actually following this.

[[folder: Tabletop Games ]]

* In D20Modern, there is a feat called DoubleTap, allowing you to deal one extra die of damage to your opponent, but giving you a -2 penalty to your attack roll. It requires two bullets to use.

[[/folder]]

[[folder: Video Games ]]

* In ''VideoGame/{{Borderlands}}'' fourth DLC, the Claptrap Ninja Assassin [[spoiler: does this to the arms merchant just before the final boss battle]]. Also, the Jacob's brand of weapons (which have the highest damage) uses the lack of this as their selling point; "If it took more than one shot, you weren't using a Jacobs".
* ''VideoGame/MassEffect1'':
** If [[spoiler: Wrex dies on Virmire,]] his killer ([[spoiler: either Shepard or Ashley]]) will shoot him ''three'' times when he's already on the ground. [[spoiler: This is a pretty good practice with krogan enemies in regular gameplay, too; if you don't see the XP payout, they're still coming.]]
** At the end, Shepard tells his / her companions to check if [[spoiler: Saren]] is really, absolutely dead after he has already either [[spoiler: shot ''himself'' [[BetterToDieThanBeKilled in his last lucid moment]]]] or [[spoiler: been impaled through the chest]]. One of them will give the body another shot to the head. [[spoiler:But anyone being slightly GenreSavvy knows right away that if the developers added that scene, the body will get up again.]]
* In the opening level of ''VideoGame/MassEffect3'', Liara suspends a few Cerberus troopers in the air with Singularity, shoots them, then puts a few more rounds in them when they're on the ground.
* The protagonist of ''VideoGame/FalloutNewVegas'' gets doubletapped at the beginning of the game - and ''survives''.
** Follows-Chalk shot a White Leg in the head twice after bludgeoning him with his club the first time you meet him. Apparently, Joshua Graham has trained the Dead Horses tribals to do this, as can be seen in the final battle.
** The Ghost People in the Dead Money DLC require this treatment, due to their unique ability to continuously come back to life unless they've lost a body part.
* In ''[[VideoGame/CallOfDutyWorldAtWar World at War]]'' and ''[[VideoGame/CallOfDutyBlackOps Black Ops]]'' [[NaziZombies zombie mode]] there is the Double Tap Root Beer item, which causes every pull of the trigger to fire two rounds, even when using pump action shotguns or bolt action rifles. While doubling your rate of fire sounds fun, scarcity of ammo can to push this into AwesomeButImpractical.
** ''[[VideoGame/CallOfDutyBlackOps 2]] changed it to Double Tap II Root Beer, which now doubles your bullet mid-flight.
* A Sniper with the "Croc-O-Style" item set in ''VideoGame/TeamFortress2'' will not be killed by headshots and thus will require a double-tap to kill.
** A Spy wielding the [[HandCannon Ambassador]] can kill weaker classes in as few as 2 shots.
** Most weapons in general take at least two shots to kill any class at (standard) full health: point blank the Rocket Launcher, Scattergun, and the Grenade Launcher all do just under 125 damage (health of the Scout, Sniper, Engineer, and Spy) in one hit.
* In ''VideoGame/SpecOpsTheLine'', one of your {{Finishing Move}}s is this.
* In ''VideoGame/{{Thwaite}}'', a balloon or MIRV that has split into three pieces may require more than one missile to destroy. The reliable way to blow them up is to put one missile between two of them and another in front of the third.
* In ''VideoGame/SaintsRowTheThird'', this is one of the {{Finishing Move}}s on Brutes - backhand the GiantMook onto the ground, then shoot it in the head repeatedly until it explodes.

[[folder: Webcomics ]]

* PlayedForLaughs in ''Webcomic/{{Homestuck}}''. Caliborn use a double tap with a Machine gun on Gamzee's corpse... after blazing at him with full auto for an [[BottomlessMagazines indeterminate amount of time]], at least several panels straight.
** Made even funnier by the fact that Gamzee ISN'T EVEN DEAD after all that, because he's a MonsterClown and They. Never. Die.

[[folder: Western Animation ]]

* ''JonnyQuest'' episode "A Small Matter of Pygmies". After downing a black leopard, Race Bannon shoots it again to make sure it's dead.

[[/folder]]

[[folder: Real Life ]]

* There's the Mozambique Drill, which is a quick double tap to the chest followed by an aimed shot at the head, designed for close-range encounters.
* British Special forces [[http://www.youtube.com/watch?v=XHzElqfzMtc are taught]] to double-tap the head, if possible in the "T" (a line from temple to temple, then down the nose), because body armor has become an awful lot easier to get hold of nowadays.
* Osama Bin Laden reportedly took one to the chest, one to the eye.
* Many firearms instructors now teach students to shoot until the threat is neutralized, regardless of how many rounds that is, so some people now shoot triple taps or just punch out five or six rounds rapidly per target.
* Standard police training in most American districts is that if you are in a situation where you're actually shooting at someone, you '''always''' pull the trigger twice. Sometimes cops will end up firing much more than that, if it's not clear that the suspect is dead (such as if he ends up falling against a wall or a vehicle), hence the meme of trigger-happy cops [[ThereIsNoKillLikeOverkill unloading dozens of rounds into some poor bad guy.]]
* A tactic used by American pilots in the UsefulNotes/VietnamWar was "ripple fire", lobbing off one missile followed by another at a target. This was due to the [[ReliablyUnreliableGuns less than spectacular]] performance of most of the guided missiles of the time.
