Knife

For the similar weapons in Battlefield 1943, see bayonet or Type 94 Shin Gunto.

For the cut weapon in Battlefield Vietnam, see Commando knife

A Knife, or known primarily as a Combat Knife or Fighting Knife is a cutting weapon designed for military use, specifically for close combat; however, since the end of trench warfare, most military knives have been primarily designed for utility/tool use (clearing foliage, chopping branches for cover, opening ammunition crates, etc.).

Battlefield 1942
In Battlefield 1942, the Knife is issued to every kit. The Allied and Axis knives are considered to be different weapons, and as such have different skins. However, they are identical in terms of functions and stats.

Battlefield 1942: The Road to Rome
The Combat Knife is issued to the new factions and is replaced by the Bayonet for the Engineer kit's bolt-action rifle, which, when equipped, uses the aim button to thrust.

Battlefield 1942: Secret Weapons of WWII
In Battlefield 1942: Secret Weapons of WWII, the Commando Knife and the German Elite Knife are new weapons issued to the Special Air Service and to the Waffen-SS respectively. They replace the standard combat knife from the base game for these factions. They act like a normal combat knife, except they can be thrown with the primary fire key, or used as a melee weapon with the secondary fire key. Each kit comes with five knives.



Battlefield Vietnam
In Battlefield Vietnam, the Knife is issued to all American and South Vietnamese kits. Its appearance is drastically different from the 1942 version, being much larger, and held with the blade down and to the side, rather than upright. However, it does the same damage. The Axis knife was also redesigned, into the Machete.

WWII mod
In Battlefield Vietnam ' s official WWII mod, the Knife is issued to every kit. Like in Battlefield 1942, the knife's model varies between factions, with an Allied knife issued to the US Marines and an Axis knife issued to the Imperial Japanese Army. It uses the same models as those from the previous game, though uses very different animations. Its performance and stats are identical to those from its counterpart from the previous game.

Battlefield 2
In Battlefield 2, the Knife is issued to every kit, and can kill in a single hit. Unlike previous games, the combat knife's skin does not change between factions: there is a single game file related to the knife, which is used for all soldiers, rather than multiple for each faction.

Battlefield 2: Modern Combat
In Battlefield 2: Modern Combat, a Combat Knife is issued to the Spec-Ops kit, and kills in one hit, much like other Battlefield games. USMC and EU soldiers will be issued with a Model 15 Combat Knife, while PLA kits will have a Type 95 Combat Knife, and MEC kits will have the Kukri. Although they differ in appearance, they all perform similarly.

Battlefield 2142
The BJ-2 Combat Knife is issued to every kit. It kills with a single hit, and a kill will award the player with the victim's dogtag.After fifty kills with the knife, the player earns the Dogtagger Dagger, a knife replacement with a dogtag attached to the handle and is purely a cosmetic item.

Battlefield: Bad Company
The Kniv-1 combat knife is available for use for every type of kit, and can be used to attack enemies to claim their Dog Tag and break open wooden doors and fences. A hit will result in an assured one hit kill. However, it will probably take about 2 hits to kill friendlies.

Battlefield Heroes
In Battlefield Heroes, a combat knife is issued to members of the Royal and National armies utilizing the Commando class. Rather then bullet-like damage fixed on a crosshair, the knife inflicts splash-like damage, spread in an area in front of the wielder.

Battlefield: Bad Company 2


"Ideal for close quarters when the 'continuum of force' has been reduced to hand to hand combat. For optimum performance, the leading edge, 'pointy end', should be applied to the enemy and thrust into vital regions. This should be repeated as necessary."

- In-game description

Singleplayer
In Battlefield: Bad Company 2's singleplayer, the knife is the first usable weapon in the game, and can be equipped upon three occasions. The first time is after the opening cutscene of Operation Aurora where the player loses their Thompson, the player pulls out the knife and kills a Japanese guard with it. Soon after, the player receives a Type 100 and the combat knife can no longer be equipped as a stand-alone. The second time is at the beginning of the mission Upriver, when the player must use the combat knife to quietly take out a sentry at an outpost overlooking a Bolivian Militia base without raising the alarm. The third time it is used is in the beginning of Airborne, where the player is equipped with a combat knife again, this time in order to kill a Russian soldier. The player immediately picks up the soldier's AKS-74U, however, and can no longer equip the knife as a standalone weapon. Throughout most of the campaign, the player can only use the knife in an attack sequence.

Multiplayer
In multiplayer, the Combat Knife is the standard melee weapon, usable by all kits. When using the knife on an enemy within its range, roughly five feet, it will cause the player to lunge forward against the enemy and perform a stabbing attack. An attack without an enemy target will instead cause the player to slash with the knife. It will kill an enemy player in a single strike but  the weapon can be heard when utilized as the player often yells and makes a distinct noise. Players can kill certain enemies in vehicles if they are in an exposed position.

The knife is also a useful tool for knocking away certain destructible barriers, such as windows, fences, barbed wire, wooden doors, wooden railings, and many other light physical barriers in the player's path.

When players knife an enemy player in the game, they receive that player's dogtag as an award. These appear as bronze, silver or golden dogtags, depending on the victim's rank, with their name written below them. There are also several awards related to knife kills which the player can acquire. The dogtags from all of a player's past victims can be viewed in the Main Menu, providing a running tally of how many individual dogtags players have acquired as well as player-specific ones.

Battlefield Play4Free
In Battlefield Play4Free, the Combat Knife is issued to every kit. It cannot be equipped, as it works like in Battlefield: Bad Company 2, performing a slash animation when used. The knife always results in a one hit kill, providing the player with the "Close Quarters Kill" bonus for 20 points.

Battlefield 3
In Battlefield 3, the Knife is a melee weapon, providing two ways to utilize it, the standard knife slash or the new takedown method.The weapon can also be used in all three modes in the game (singleplayer, co-op, and multiplayer).

Knife attacks (whether quick or standard) can destroy chain link fences and window glass with a single blow, allowing passage through them (although there are some exceptions such as the Russian spawn building windows in Operation Metro).

Singleplayer
In singleplayer, Blackburn's and Dima's knifes are different cosmetically, Blackburn's being an M9 bayonet and Dima's being a Spetsnaz Machete. Some enemies will try to perform takedowns on players if they get close enough to them. To counter it, simply press the attack button and the enemy trying to kill you will be killed instead.

Multiplayer
In multiplayer, the game utilizes the quick knife, which reduces 50% of health per slash, and an all new takedown action which kills instantly.

Takedown
"A melee attack is always more successful from behind an opponent"

- A loading screen tip regarding Knife Takedown



Holding the button while behind or beside an anemy will perform a fatal Takedown attack. When in range of a takedown target, the knife is raised to a vertical 'ready' position—the knife is held horizontally when equipped if there is no target, or if the target is not in range. Players have to decide whether the extra time and exposure during a takedown are worth the risk, especially when other alert enemies are nearby. There are nine takedown animations in all, three for each stance.

When a takedown is performed, the knife user is awarded the victim's Dogtags which is unobtainable in any other way. When attacking with a knife, you do not appear on the radar; however, knife sound effects may reveal your position.

Battlefield Premium


The ACB-90, is a melee weapon that was based off the United Cutlery M48 Kommando Survivor Guthook Knife and is available to Premium members. It replaces the standard knife yet it only differs aesthetically, albeit using a crosshair reticle as opposed to the standard knife's dot reticle. Those killed by it will still be counted as 'knife' kills.

Singleplayer
The Knife returns in Battlefield 4 as it is seen in the 17-minute gameplay reveal trailer being wielded by Recker and is used to takedown attack a Russian soldier.

It has the same textures of the M9 Combat Knife featured in Battlefield 3 and the same exact takedown animations. Later in the trailer, Recker uses his knife again to cut part of Dunn's leg off to free him from the rubble near a burning UH-1Y Venom.

Multiplayer
Battlefield 4 marks the first time the player can select the knife type they are going to spawn with.

The standard M9 Bayonet Combat Knife, the Shank, an improvised melee weapon, aswell as the highly requested Machete, are some examples. All knifes are purely cosmetic and don't change any stats

Knife attacks can now be performed while swimming, along with use of sidearms.

Counter Attack
The Takedown mechanic from Battlefield 3 returns in Battlefield 4, albeit with a new feature that allows the potential victim to counterattack his assailant.

This is first seen in the "Battlefield 4: Official "Siege of Shanghai" Multiplayer Trailer". When under attack, the target has one second to press before the attack connects (and the player is killed). An HUD prompt also appears on the target's screen. A successful counter-attack still gives the victor the victim's dogtags.

Counter-knifing, like knifing, can also be done in the water.

Trivia
Battlefield 3= Battlefield: Bad Company 2= Battlefield: Bad Company= Battlefield 4=
 * The takedown animations during alpha were considerably longer. DICE switched to shorter animations that incorporate the removal of the victim's dogtags, and keep the first-person view steadier so the player is more aware of their immediate surroundings.
 * Mortar users are immune to takedown attacks—vehicle operators cannot be taken down, and the mortar is considered a vehicle for gameplay purposes. It is possible to provoke the user into exiting the mortar, although there is a slight risk of being struck by an outbound smoke mortar (the regular HEDP mortar round does not inflict damage until it falls).
 * There is a glitch that occurs when performing a takedown on a victim looking downsight, where the victim's cutscene is shown in magnification equal to the optics on his gun.
 * A complicated glitch allows players to teleport to an arbitrary point above certain maps after performing a takedown, with enough height to safely parachute down.
 * The ACB-90 knife given to Battlefield Premium users is based on the United Cutlery M48 Kommando Survivor Knife.
 * Battlelog tracks knife swings under "shots fired".
 * It is possible to score a headshot with the quick knife attack, which can kill an enemy with full health.
 * A glitch introduced after one of the 2012 patches limited the number of consecutive takedowns to one, causing players to not attack for up to five seconds. It has since been patched in the October 11th server update.
 * If caught in a takedown from certain angles, it is possible to counter the attempt with a Quick Knife attack. Certain animations will place the attacker's body in the victim's crosshairs, allowing the victim's knife attack to kill the attacker if already weakened below 50 health. A few of these even hit the attacker's head, permitting a headshot (2× 50 damage). Takedowns from behind cannot be countered, nor can takedowns on crouching victims.
 * It is possible to score a simultaneous double kill with the knife. This may either be a case of latency causing both enemies to be caught in a takedown, or the "shot" from the takedown on one enemy also striking the second enemy.
 * This is the first Battlefield game where the player does not wield the knife as a weapon—it now functions more as a melee attack option. The player just uses the knife then puts it away instantly, returning back to wielding the previously equipped item. The only exceptions of this are the beginnings of Operation Aurora and Airborne.
 * A glitch can occur when the player is climbing a ladder. If the player starts climbing in mid-slash, they will equip the knife after reaching the top.
 * An update reduced the lunge distance for the combat knife.
 * Occasionally, after slashing with the knife, the player character may hold their knife for a few seconds the same way as in the mission Operation: Aurora, usually during a small lag spike.
 * It is possible to cut down small trees with the knife.
 * -|Battlefield Vietnam=
 * The files for the ARVN and U.S. knives are the same as those used by the allies' knife in Battlefield 1942, with a different model. The axis combat knife still exists in the game files, but goes unused, replaced by the NVA and Viet Cong melee weapons.
 * The knife and takedown animation seen in the 17-minute gameplay trailer could possibly be placeholders for the Pre-Alpha and might be changed later in the game's development.
