Frag Grenade

The Hand Grenade is a small, light-weight, timed explosive device. Grenades can inflict severe damage against infantry and other soft targets, but do not inflict much damage on armored vehicles such as Tanks. Most hand grenades used are fragmentation grenades, often abbreviated to "frags", which litter an area with shrapnel, inflicting severe damage on infantry and lightly armored targets. Another type of hand grenades is the Concussion grenade, which is - filled with High Explosives - more effective on armored targets but slightly less effective against infantry when compared to a fragmentation grenade, and are as such usually used by soldiers as a weapon against vehicles. Hand grenades have been featured in every Battlefield game to date.

Battlefield 1942
In Battlefield 1942, Grenades are issued to all classes, except the Engineer Kit. They can cause a large amount of damage over a large radius, easily killing infantry in a single blast, but it takes 3 seconds before detonating, so tracking a target is required to kill. Throwing them in bottle neck positions, such as bridges or in buildings, can easily clear a large amount of infantry.

They are also quite effective against vehicles. Only two grenades are needed to destroy light vehicles like a Willys MB or a Katyusha, and the blast can also throw these vehicles off and deviate them. They are not so effective against tanks, but they can cause a substantial amount of damage if they explode under the tanks.

The grenades come in the Mk.II or Stielhandgranate variants, depending if the player is on the Allies or Axis respectively. The German and Italian Stielhandgranates will have German writing on them, whilst the Japanese ones will have Japanese kanji on them.

Each Kit with hand grenades carries a maximum of 3.

Battlefield Vietnam
In Battlefield Vietnam, Grenades are almost always issued to the Assault Kit of any faction and an option for the Heavy Assault Kit of the NVA. The only exception is when the hand grenades are replaced by the XM148 grenade launcher on a CAR-15. They act as they do in Battlefield 1942. The Americans and South Vietnamese use the Mk.II Hand Grenades, whilst the North Vietnamese and Viet Cong use the M24 Stielhandgranate.

Each Kit with hand grenades carries a maximum of 4 grenades.

WWII mod
In Battlefield Vietnam ' s WWII mod, Grenades are issued to the Assault, Heavy Assault, Scout and Flamethrower kits. They have the same stats and performance from the base game, and use the same models; the NVA grenades are used by the Imperial Japanese Army, whilst the American grenades are used by the US Marines.

Battlefield 2
In Battlefield 2, Hand Grenades are standard issue to each playable faction. They are found on all Kits except the Assault Kit, which replaces them with an under-barrel grenade launcher, and the Anti-Tank Kit, which uses a rocket launcher instead. As the G3 unlock for Assault has no grenade launcher, the Kit comes with grenades when it is used. They have the same stats for each team, as well as using the same model (an M67 Fragmentation Grenade).

All Kits except the Assault and Anti-Tank Kits receives 4 grenades.

Battlefield 2: Modern Combat
in Battlefield 2: Modern Combat, Grenades are issued to every kit except the Assault Kit which has an underbarrel grenade launcher in their place, much like in Battlefield 2.

Battlefield 2142
In Battlefield 2142, two FRG-1s are made available as the first non-kit unlock. If a player has unlocked the "Extra Grenade" ability, they will have three grenades when spawning. They have a decent amount of power, easily killing lightly armored infantry. Heavy armored infantry can still be killed by them, but they will need to be closer to the blast. Both the European Union Army and the Pan-Asian Coalition Army use the same model for the grenade.

Battlefield: Bad Company
In Battlefield: Bad Company, HG-2s are given to the Assault, Specialist Kit and Demolition Kit. It is a secondary weapon, so one must switch to it and then throw it. It inflicts high damage to infantry, often killing with a single grenade, but has relatively no effect to vehicles. With the amount and effectiveness of grenades, many players simply throw grenades at enemy bases until they get a kill; this is known as grenade spamming.

Each Kit has a maximum of 5 grenades.

Battlefield 1943
In Battlefield 1943, Hand Grenades are given to the Rifleman Kit and Infantry Kit for the IJN (Type 97) and the USMC (Mk.2). Their performance is exactly the same as in Battlefield: Bad Company, only the player isn't obligated to switch to them, the simple press of the button will immediately cook and the release of the button will throw it.

Each Kit has a maximum of 3 grenades (once all used, the amount "regenerates").

Battlefield Heroes
In Battlefield Heroes, there are two varieties of the hand grenade. The grenade can only be used by the Soldier Class, either using it as an explosive weapon or through the ability "Grenade Spam". The "Grenade Spam" ability allows the user to throw multiple grenades at once. The National Army's grenade is similar to a World War II-era German M24 Stielhandgranate while a Royal Army grenade is similar to the Allies most widely-used grenades; the Mk 2 and the Mills Bomb.

Battlefield: Bad Company 2
In Battlefield: Bad Company 2, the grenades are always given to the player, in both single and multiplayer.

In singleplayer, the player starts off with four grenades as default, and can refill them from dead enemies, ammunition boxes or Supply Crates. The hand grenades are very useful against AI soldiers, as the AI infantry have low health and commonly don't react to grenades thrown near them, and can also be useful at creating easy fire zones or "rat-runs", which can be very useful in levels such as Sangre del Toro and Snowblind, where buildings are commonly present. However, against vehicles and other structures such as bridges and towers, the M2 Carl Gustav and C4 satchels are much more effective than the hand grenade.

In Multiplayer the player only spawns with a single grenade without the Grenade Vest specialization, though this can be refilled through the use of ammunition boxes. Even though it can be thrown a considerable distance, throwing one accurately at long range requires practice. Grenades have a long fuse, so the movement of enemy players must be accounted for along with the surface the grenade will land on, because it may roll and bounce if it lands on a slanted surface. It can be held indefinitely and even canceled if the opportunity disappears. Though generally more useful to unskilled players who may pull a grenade before entering any enemy appears, it also presents a disadvantage to more skilled players who are thus prevented from cooking the grenade to create an air burst effect.

A single grenade can kill an enemy at full health, although the target needs to be in close proximity to the grenade for this to happen. However, the wide 2.9 metre blast radius of the grenade makes it a good assault weapon, injuring hostile players, eliminating soft pieces of cover and generally forcing enemy players to reposition, which can be useful in close-quarter combat, such as on White Pass or Isla Inocentes. When a player throws a grenade at an enemy, the enemy will audibly yell out a warning to team-mates in the area. This allows the player to identify the presence of enemies inside the target zone and potentially injure or kill some of them before breaching. Also, both sides will be alerted of thrown grenades with a small orange grenade shaped symbol with a flashing arrow under it when a grenade is thrown near their position.

Grenades can work well against vehicles such as the ATV or Personal Watercraft, due to their lack of armour and low damage threshold, as well as even larger wheeled vehicles if the grenade lands directly beneath the vehicle. However, Tanks and APCs take little damage from grenades, so this method is not advisable unless they only have minimal health remaining.

Battlefield Play4Free
The Hand grenade returns in Battlefield Play4Free as a gadget available for every kit. It can be obtained spending points in the Frag grenade training option and its explosion range is about 5 meters; higher levels of the Frag grenade training option increase the number of grenades carried and their damage against vehicles.

In Battlefield Play4Free grenades are a great anti-tank weapon and their use is recommended if there are no Engineers or stationary AT's. Also, after buying all the four levels in the Frag grenade training option one can also purchase Dead Man's Trigger to drop a live grenade with a smaller blast radius.

Battlefield 3
In Battlefield 3, at least one Hand Grenade is available for all classes. Players have the option to immediately throw a grenade (like the "Quick Slash" for the Knife), equip it as a wielded weapon (like in older games), or assign both actions via key binding.

An orange dot indicator marks any active grenade. At close range (where the player can be killed by the blast), the dot is also surrounded by an animated circle. Nearby players will automatically use voice responses when throwing or sighting a grenade.

With the Frostbite 2 engine and Destruction 3.0, hand grenades, and all other weapons, cause more realistic damage. Grenades can kill players through certain kinds of walls due to blast pressure. This can be seen in the "Fault Line" gameplay.

Grenades—and other explosives—take a lot longer to resupply than firearm ammunition, probably to cut down on grenade spam.

Trivia

 * In Battlefield Vietnam ' s WWII mod, the Imperial Japanese Army character models clearly show Type 97 grenades strapped on their belts, despite using Stielhandgranates.
 * With the Frostbite Engine and Destruction 2.0, grenades can cause slight ground deformation and destruction to light environment.
 * In Battlefield 2, the hand grenade is an American M67, no matter which team the player is on.
 * In Battlefield: Bad Company, the grenade had the trademark smiley face pin attached to it, and, despite common statements, it can also be seen in Battlefield: Bad Company 2. If the player just watches the animation of throwing a hand grenade in Battlefield: Bad Company 2 in slow-motion, they can just see the smiley face attached to the pin. It is still on the grenade's model, so the player can see it briefly when throwing it and when it is on the floor before detonating. It can even be seen on grenades during Operation Aurora.
 * Grenades are infamous in the Battlefield games for players' tendency to grenade spam by constantly throwing grenades in the hopes of getting kills. This was a severe problem in Battlefield 2 as players of all Kits (except the Anti-Tank Kit and Assault Kit) were given 4 grenades on spawn, thus allowing many players to grenade spam. It was worsened with the Support Kit as the ammo bags would replenish the used grenades, allowing for an infinite grenade effect.
 * EA had made a short-lived ad campaign for Battlefield: Bad Company 2 called "F.R.A.G.S" ("Friends Really Against Grenade Spam"), starring CC Sabathia and Sweetwater talking about how ineffective randomly thrown grenades are in Battlefield: Bad Company 2.
 * It is possible to shoot a grenade, causing it to detonate early, allowing players to kill an enemy or disable an armed grenade in action.
 * When pressing the grenade throw button while walking, or when jumping right after pushing the throw button, will help the player extend the throwing range, which will help them in killing targets behind cover from further away.
