The Mk 2 grenade (sometimes referred to as the M2 Fragmentation Grenade) was a fragmentation hand grenade commonly used by the American soldiers during World War II. It appears throughout all the World War II-themed Call of Duty games, as well as the DS version of Call of Duty: Black Ops, the DS spinoff of Modern Warfare 3, Defiance, and Call of Duty: Black Ops III.
Call of Duty and United Offensive
- "Fragmentation grenades are very effective anti-personnel devices. The high explosive charges reduce their metal casing to flying fragments, causing considerable blast damage. Though they're ineffective against armoured vehicles, they are extremely useful for clearing out entrenched infantry positions."
- — Call of Duty manual description.
The M2 fragmentation grenade, AKA "frag", is the American grenade of choice. It has fairly good throwing range and blast radius, but its ammo is very limited, and replaced by the Stielhandgranate.
The Mk 2 Grenade is issued to the Americans. In Call of Duty and its expansion pack Call of Duty: United Offensive, all grenades are statistically similar. They have a damage range of 250-10 in single-player, and 120-5 in multiplayer, with a fuse of five seconds. They also have a melee attack that deals 50 damage, with an animation similar to a pistol whip. The maximum number of grenades one can hold is 10, although in practice this only occurs in single-player. In multiplayer, grenade distribution is determined by the weapon the player spawns with. Those equipped with a Springfield receive one grenade; those with the Thompson or BAR receive two; and those with the M1 Carbine or M1 Garand receive three. Importantly, in Call of Duty, players cannot be shellshocked by grenades.
In Call of Duty: United Offensive, the damage and the maximum number of grenades stays constant, but a few changes are enacted. Players can be shellshocked by grenades. Grenades also have the ability to be cooked, where the grenade is armed but kept in the player's hand so that the fuse is shortened when thrown. Grenade distribution is totally changed as well; instead of being determined by the weapon equipped, it is determined by rank. Privates spawn with one grenade, Riflemen with two, and Platoon Sergeants with three.
Call of Duty: Finest Hour
This grenade is used by British and American soldiers. However, it has a smaller blast radius and less damage when compared to the Stielhandgranate.
Call of Duty 2
This weapon is the American grenade of choice. It is uncommon, and is exactly the same as the other grenades. It cannot be cooked just like the other grenades in the game, but can be held in hand (fuse doesn't change).
This weapon is issued to the American team. It is exactly the same as the other grenades. In Call of Duty 2, one Mk 2 Grenade is issued to those equipped with the Grease Gun, M1897 Trenchgun, or Thompson, two for those with the BAR, M1 Carbine, or M1 Garand, and three for those with the Springfield.
Call of Duty 2: Big Red One
- "This fragmentation grenade was commonly known as the "pineapple" due to its distinctive shape. Blast radius of over 30ft."
- — Description
The M2 Frag Grenade (referred to as US MK2 Grenade in the Bonus Materials) is the standard American grenade. In campaign, up to ten MK2 grenades can be carried by the player (or ten lethal grenades in total if both the MK2 and the Stielhandgranaten are combined in the player's inventory).
Call of Duty 3
- "Hand grenade often referred to as a "pineapple" because of its cross-hatched exterior. Pulling the pin and releasing the spoon allows some time to "cook" the grenade before it explodes."
- — In-game description
The Frag Grenade (listed as Mark II A1 "Pineapple" in the bonus materials) returns in Call of Duty 3. It is the standard grenade used in the American campaign, and is used by the Allied team in multiplayer. There is an on-screen counter which notifies the player as to when the grenade will explode. In multiplayer, it performs identically to the Stielhandgranate.
In campaign, the player can carry Mk 2 grenades and Stielhandgranaten in the same slot. While they can carry a maximum of four Mk 2 grenades, up to six lethal grenades in total (Mk 2 and Stielhandgranaten) can be held.
Call of Duty: World at War
In Call of Duty: World at War, during the campaign, the Mk 2 is the standard fragmentation grenade for the United States Marine Corps. The player will always have four at the start of an American mission, but they almost never are found in the actual level to be picked up.
There is a perk called Toss Back that allows these grenades to be picked up and have their fuse reset so they can be effectively thrown back.
Call of Duty: World at War (Nintendo DS)
The Mk 2 Grenade appears in Call of Duty: World at War (Nintendo DS) as one of the two grenades available in game, the other being the German Stielhandgranate. Though meant for use by Americans, the Mk 2 is used by the Red Army and the Imperial Army as well. It also differs slightly in appearance compared to the console versions, sporting a gray color scheme as opposed to a green one.
In the campaign, the Mk 2 is a starting grenade for the USMC, the SAS, and the Red Army. The player always starts with five grenades, the maximum, but can resupply from grenades found on the bodies of enemies or from ammunition crates. As mentioned before, the Mk 2 is also used by members of the Imperial Army and the Red Army.
In multiplayer, the Mk 2 is used by all factions with the exception of the Germans, which use the Model 24 Stielhandgranate. Unlike multiplayer on the consoles, all players are equipped with five Mk 2s (or Stielhandgranaten for the Germans) when they spawn. Though grenades cannot be resupplied from the bodies of enemies or from ammunition crates, the five provided grenades encourages grenade spamming.
Call of Duty: World at War: Final Fronts
The Mk 2 Grenade is used by all allied divisions depending on what kind of grenade is picked up. It shared the appearance of its Call of Duty: World at War counterpart. It can be cooked for six seconds before exploding and killing the player. Sometimes even cooking and then throwing after four seconds can still kill the player. It is advised to cook the grenade when clearing out a fortification as the enemy can attempt to throw back the grenade. On some levels, cooking grenades is best used as an unexpected enemy attack that happen at random times, which renders primary and secondary weapons a poor defense, requiring for the player to use explosive weapons.
Call of Duty: Black Ops
Call of Duty: Black Ops (Nintendo DS)
The Fragmentation Grenade appears in Call of Duty: Black Ops (Nintendo DS), in use by all teams. It is used like a separate weapon, so the player must take it out and manually throw it.
Fragmentation Grenades appear as the main grenade in the Zombies mode. It is also purchasable from the walls. It is not very effective, because as was stated before, it has to be taken out manually.
Call of Duty: Modern Warfare 3: Defiance
The Grenade is featured in Call of Duty: Modern Warfare 3: Defiance and retains the same stats of the Mk. 2 from Call of Duty: Black Ops (DS), only it now has a metallic color.
In the campaign, the Mk. 2 Fragmentation Grenade is the only grenade available to use and can only be resupplied at ammunition crates and dropped by some enemies. The player can have up to five grenades maximum.
In multiplayer, the Mk. 2 is one of the starting weapons and automatically unlocked, along with its counterpart, the Flashbang Grenades. The grenade has the same statistics as single-player.
Call of Duty: Ghosts
The Mk 2 was briefly seen in Call of Duty: Ghosts in the introduction cutscene for the Extinction map Awakening. One of the soldiers with David Archer pulls it out but drops it after a Gargoyle attacks him. Archer uses another soldier as a shield, to which the blast from the grenade kills him.
Call of Duty: Black Ops III
