A weapon or ability that is effective against basic infantry units. Typically involves KillItWithFire, if not specialized munitions or MoreDakka. HerdHittingAttack-style weapons or abilities are also often used.

For the sake of CompetitiveBalance and TacticalRockPaperScissors, many anti-infantry-specific weapons are near useless against sufficiently armored enemies.

SubTrope of WeaponOfXSlaying. See also AntiAir, AntiArmor, AntiCavalry, AntiVehicle and AntiStructure.

!!Examples:
[[foldercontrol]]
[[folder:Anime & Manga]]
* ''Manga/TheFiveStarStories'': Exaggerated. See all those little divots in the average Mortar Headds' armor? Chances are each one has an anti-personnel laser and/or grenade launcher inside it.
* ''Anime/MobileSuitGundam'':
** Most Gundam designs carry Vulcan Cannons on their helmets, designated as both point-defense and anti-infantry weapons.
** ''Anime/MobileSuitGundamThe08thMSTeam'' shows both the Apsalus and Zaku II are armed with "anti-personnel weapons", specifically bounding mines that spread shrapnel over anyone [[ColossusClimb trying to assault the cockpit without a vehicle]] but bounce harmlessly off the suit's armor. [[spoiler:When Shiro takes out the legs of Topp's Zaku to spare her life, the guerrilla he was working with [[SinkTheLifeboats rush in to kill her anyway]]. Topp uses the anti-personnel weapons to slaughter them all, then Shiro ends up killing her anyway.]]
** ''Anime/MobileSuitGundamSEED'': The 105 Dagger has small-calibre vulcans mounted in its ''feet''. They're shown being used (with very visceral results) in the OVA ''Anime/MobileSuitGundamSEEDCE73Stargazer''.
[[/folder]]

[[folder:Literature]]
* ''Literature/{{Bolo}}'': The stories sometimes mention anti-personnel weapons meant to be used against enemy infantry.
* ''Literature/HammersSlammers'': The panzers have anti-personnel mines attached to their armor. Since infantry can still sneak up on a hovertank and take it out with a cheap buzzbomb, these mines are necessary.
[[/folder]]

[[folder:Tabletop Games]]
* ''Tabletopgame/BattleTech'':
** While they have their usefulness in HumongousMecha combat (for example, by overheating an enemy 'Mech and thus disabling it), flamethrowers and machine guns are much more typically equipped to deal with attacking infantry. Among other Battlemechs designed around such capability, there's the appropriately-named "Firestarter" series. Anti-personnel Gauss Rifles are also fearsome infantry-killing weapons that fire [[FlechetteStorm gobs of small projectiles]] that carve up conventional infantry formations at three times the range of a machine gun.
** Battle Armor are banes to unarmored infantry. Clan Elementals are 10 ft juggernauts capable of surviving hits from mech weapons, and will easily mow down infantry with flamers, machine guns, and anti-personnel weapons (typically a sub-machine gun of some sort). Some suits also mount fearsome infantry-killing melee weapons like [[VibroWeapon Vibro-Claws]]
* ''TabletopGame/CarWars'' has this as a limitation on most pedestrians' weapons. After all, if a car is built to handle a few seconds of 7.62mm machinegun fire, it likely won't be as hurt by, say, a 9mm handgun. There are a few pedestrian weapons that are effective on cars, though; notably, the axe and hatchet, for those who feel like going into melee.
* ''TabletopGame/{{Ogre}}'': The titular cybernetic tank has anti-personnel weapons used against the armored-suit infantry of its opponents.
* ''TabletopGame/{{Paranoia}}'' had several gas grenade types (and cone rifle warheads) that only affect people.
** Poison: does physical damage, can kill.
** Vomit: causes uncontrollable retching.
** Hallucinogenic: "Oh look, there's a unicorn! And my flashlight is talking to me!"
* ''TabletopGame/Warhammer40000'' has several vehicle variants on each faction that the fluff describes as more effective against infantry. Alongside specialized weaponry or ammunition that works best at taking care of several infantry at once.
** The Hellhound Tank and its Banewolf variant are a series of light tanks that provide fast fire support for the Imperial Guard and take care of anything that's hiding in cover. The Hellhound is armed with the Inferno Cannon, a unique vehicle-mounted flamer that can project its fiery payload over a both a considerable distance and a wide area. The Banewolf has the Chem Cannon which are toxic waste-throwers, spraying a highly concentrated and poisonous toxic cocktail that can even affect PowerArmor. Both are very effective against massed infantry.
** The ''Devastator''-Pattern Leman Russ tank has dual autocannons effective against anything with light armor, but again the fluff describes as an "anti-personnel" variant of the tank... which says a lot about the kind of monsters commonly considered "enemy personnel", actually. The ''Punisher''-Pattern Leman Russ tank is instead armed with an enormous gatling gun capable of turning a massive enemy army into red mist.
** The Space Marines' handheld missile launchers and the Ork Kannons are good examples of the difference between anti-infantry and anti-armor, since they both allow to choose between two kinds of ammo: one is a single-target high-power round ("krak" missiles), while the other is weaker but with an AreaOfEffect (frag missiles).
** Attilan hunting lances can be fitted with frag tips, which detonate in clouds of shrapnel designed to clear crowds of enemy infantry.
* ''TabletopGame/{{Warmachine}}'' has plenty of Warjacks that excel in mowing down infantry. The Cygnar Cyclone for one has pair of [[GatlingGood chain guns]] as its weapons.
[[/folder]]

[[folder:Video Games]]
* Infantry in ''VideoGame/AdvanceWars'' are individually the weakest units, but can be deployed ''[[ZergRush en masse]]'' at little cost (albeit standard Infantry are better at blocking the enemy than doing damage). Thus, Infantry is best dealt with by units that can do it quickly ''and'' on the cheap.
** Recon vehicles are barely stronger than Infantry, but are almost as cheap, resistant to Infantry machine guns, and ''very'' mobile on roads and properties. When not scouting in FogOfWar, they're usually sent off to attack Infantry trying to capture properties, especially in the early game before there will be other units to protect them.
** The [[AntiAir Anti-Air]] vehicle unit is poor against land armor, but compared to anything else in its price range does moderately higher damage to Infantry--often just enough for a OneHitKill.
** Though [[GlassCannon Mechanized Infantry]] bazookas can severely damage most land vehicles, they can only attack air vehicles with their much weaker machine guns, leaving them almost defenseless against Battle Copters.
* ''VideoGame/AztecWars'': The bears and jaguars do wonders against infantry, but are rather useless against buildings and vehicles.
* ''VideoGame/BrothersInArms'':
** The Browning [=M1919=] and the MG-42 are fixed machine-guns capable of killing enemy infantry in [[OneHitKill one hit]]. In ''Hell's Highway'', portable versions of these machine-guns appear, and are the standard-issue weapon for machine-gun teams of both the Americans and Germans.
** In terms of artillery, there's the 88mm Flak 36 gun. While normally used in the AntiAir or AntiArmor role, the gun can also be used to attack infantry, as demonstrated late in ''Earned in Blood'' and well into its sequel.
* ''VideoGame/CommandAndConquer'':
** ''VideoGame/CommandAndConquerTiberianDawn'' has the flame tank from the Brotherhood of Nod. GDI have the Wolverine to fill this role for them.
** ''VideoGame/CommandAndConquerRedAlert'': The first game has the Yak, a plane that strafed targets with machine guns and earned the nickname "Infantry Eraser".
** In addition to [[CarFu all vehicles being able to run over enemy infantry]], ''VideoGame/CommandAndConquerGenerals'' has each three sides having at least one or two units that excel in this (and one unit each to instantly clear out GarrisonableStructures). The USA has [[ColdSniper infantry-sniping Pathfinders]], Rangers with flashbang grenades, and Humvees[[note]]that can be occupied with anti-infantry infantry units[[/note]]; China has the [[FireBreathingWeapon Dragon]] and [[MoreDakka Gatling]] tanks; and the GLA has the Toxin Tractor, the Technical, the Quad Cannon and [[HeroUnit Jarmen Kell]].
* ''VideoGame/CompanyOfHeroes'' has most units use a weapon that will be at least usable against infantry, if not especially good at it (the especially good ones usually either having a [[MoreDakka high rate-of-fire]] or [[HerdHittingAttack simply explodes over a large area]]). The minority that aren't are anti-vehicle specialized weapons, which ''can'' kill unfortunate infantryman in a single hit [[ChunkySalsaRule due to their power]], but are encumbered from being particularly useful in that regard by a low fire-rate and abysmal accuracy against man-sized targets and make actually killing them in most cases a miracle.
* ''VideoGame/DarkReignTheFutureOfWar'': Each side has one that specialize in this. The Imperium have their Shredder that instantly kills infantry it can hit with its blades. The Freedom Guard have their Sniper that can snipe infantry from afar.
* ''VideoGame/DawnOfWar'': The game divides its infantry into regular (Guardsmen, orks...) and heavy infantry (SpaceMarines). A good rule of thumb is that the higher the rate of fire, the better against regular infantry (heavy infantry is best taken out with plasma weapons), although artillery is remarkably effective at scattering and killing infantry. The Orks have Flash Gitz that excel in shredding infantry, and heavy infantry with lots of dakka. They can easily gun down infantry from afar but they are bad in melee.
* ''VideoGame/EnemyTerritoryQuakeWars'': Engineers can place an anti-personnel defensive turret (a machine gun). It will only attack soldiers, though-which means that it's possible to attack it freely with a vehicle if it's undefended.
* ''VideoGame/FireEmblem'':
** Subverted by TutorialFailure in the GBA games. The handful of weapons labeled as "effective against infantry" are actually AntiArmor and AntiCavalry. How this is supposed to add up to "infantry" is never explained.
** ''VideoGame/FireEmblemHeroes'': The Poison Dagger weapon inflicts bonus damage against infantry units.
* ''VideoGame/HaloWars'': The UNSC has Hellbringers, marines equipped with flamethrowers, while the Covenant has Jackal. Hellbringers are close-range units while Jackals are suited for long-range.
** ''VideoGame/HaloWars2'': The UNSC has Hellbringers just like before, but also adds Snipers. Snipers can engage enemies while obscured by the FogOfWar, but are limited in that they can only attack infantry units and nothing else, not even buildings. The Banished have Suicide Grunts and Elite Rangers, the latter of whom can attack any type of enemy.
* ''VideoGame/MastermindWorldConqueror'': The [[FireBreathingWeapon flamethrower upgrade]]. Not very useful on its own, but the only type of enemy that attacks the Moonbase is infantry.
* ''[[VideoGame/MasterOfOrion Master of Orion 2]]'' give the Neutron Beam and Deathray the attribute of killing the crew on an enemy ship in addition to their standard damage to a ship's hull. The intense radiation of these weapons is lethal to living organisms and a few shots from these will make it easy for your own commandos to board a ship and commandeer it.
* ''VideoGame/MechCommander'' and its sequel have both standard and PoweredArmor infantry, carrying small lasers, machine guns, and missiles. Unlike [[TabletopGame/BattleTech the source material]], you have to target each trooper individually. Weapons with fast fire rates tended to be the best option, since any one hit would take one trooper out, but it needed to ''hit'' a trooper first. Sheer volume of fire means that [[BeamSpam pulse lasers]] and [[MoreDakka rapid-fire autocannons]] worked best against infantry.
* ''VideoGame/MechWarrior'': In the ''Mech Warrior: Living Legends'' fangame, most AntiAir assets also double as AntiInfantry against the PersonalSpaceInvader [[PoweredArmor Battlearmor]], courtesy of their [[MoreDakka high-powered, rapid-fire autocannons]] being able to shred battlearmor with only a few shots. LB-X buckshot shotguns carried by some of the anti-air assets also create a satisfying [[LudicrousGibs spray of blood and gibs]] and are much easier to use against battlearmor currently using their JetPack. The best anti-infantry weapon is the Short Ranged Missile, which sprays up to 6 missiles towards the crosshair with enough damage and splash to rip a battlearmor player to pieces -- although they are nigh-unusable against clever battlearmor who never lands within the SRM's firing arc.
* ''VideoGame/StarCraftI'': The game has anti-infantry measures among the three factions, but some aren't heavily restricted to just Infantry targets. Terran Firebats are excellent for killing swarms of Zerglings with their flamethrowers or raiding worker units, but do poor damage against non-light targets and have very limited attack range. The Zerg have Lurkers who are effective against swarms of tiny units too, but they also do their full damage to any unit. The Protoss have Reavers and High Templar for dealing with swarms of units or any large targets of opportunity, the former being well suited to the task thanks to the ability keep firing as long as the player keeps commanding them to build more scarabs to launch.
* ''VideoGame/WarcraftIIIReignOfChaos'': Averted in that armor and damage types are distributed among all units, so an orc grunt and a siege catapult can be weak to the same type of damage. Some melee units take more damage from melee than from ranged, some have the inverse, some take more damage from magic, etc.
* ''VideoGame/WorldInConflict'' has a few:
** The Sniper is extremely deadly to infantry of all kinds, especially if he is well hidden in the woods or perched atop a tall building.
** Napalm and gas canister Tactical Aids are pretty much the only efficient ways to flush out enemy infantry hidden in the woods or inside the buildings (only gas works on infantry in the buildings, but it helpfully leaves the buildings intact).
** Heavy artillery Tactical Aid has universal effect but works best on infantry standing in the open (heavier units can generally escape the bombardment area before dying; infantry can't).
