Notes: This grenade produces a dense cloud of white smoke without the intense incendiary effects of WP grenades (although it is hot enough to occasionally ignite easily combustible substances like hay or dry grass).

The Model 308-1 White Smoke Grenade is a modified ANM-8 designed and produced by Naval Warfare Center China Lake. It is the same size and weight as the ANM-8, and also produces white smoke, but has a longer burn time. The Model 308-1 burns for four times as long as a standard smoke grenade (including the periods of less dense smoke). The Model 308-1 is generally found in use only by US special operations forces.

Notes: This is a thermite grenade. Thermite is a chemical composition, which produces extremely high heat when ignited. Grenades of this type are used to destroy equipment (it will destroy a gun breech or engine block within minutes) or to ignite fires or ammunition (the grenade burns at 2200ºC). The ANM-14 burns for 9 combat phases (45 seconds). The burst represents sputters of molten metal scattered in random directions and is treated as a burn.

Notes: This irritant gas grenade is based on perhaps the most severe form of irritant gas, known as DM, and also contains CN. DM (also known as Adamsite), is a far more powerful irritant than CS or even CN; it straddles the line between irritants and damaging chemical agents, as it can be toxic and even lethal with too long an exposure. The M-6A1 grenade’s cloud produces incapacitation unless the victim makes an Impossible: Constitution roll successfully; there is no panic roll, since the gas is instantly incapacitating without a successful Constitution roll. Incapacitation produces symptoms similar to irritant gas for the first minute; the next two minutes produce sneezing and coughing as well as irritant gas symptoms. These all increase in severity for another two minutes, and then severe headaches, sharp pain in the nose and chest, and nausea and violent vomiting join the symptoms. At this final stage, no further Constitution rolls are possible to allow the victim to continue or resume functioning, but an Easy: Constitution roll is required every further minute in the cloud to avoid taking one point of damage to the head and chest. Once removed from the cloud, incapacitation rolls at Difficult: Constitution must be made every ten minutes for the next 4 hours, or all the symptoms begin anew. Once one such roll is made, the victim will suffer no further incapacitating effects, though some minor symptoms may remain as long as 12 hours.

These grenades are rare, and are primarily used by US, NATO and Israeli special operations forces.

Notes: This grenade is similar to the much more common M-7A3 shown below, but uses CN instead of CS gas. CN is a much stronger, more concentrated form of tear gas, which produces quicker and more severe results. It is also an earlier form of tear gas, pre-dating CS by about a decade. Like the M-7A3, it can produce fires as it burns in a very hot manner. The same adapter which can project an M-7A3 grenade may also project an M-7A1 grenade; they are virtually identical in size and shape (except for the striker mechanism atop the grenade). Those who are in a CN gas cloud react in a similar manner to those in a standard irritant gas cloud, but the character must make a FOR: Constitution check to avoid being overcome by the gas. In addition, the initial panic roll is at -3. A victim who is overcome by CN continues to suffer the effects for 15 minutes instead of 10, and is probably vomiting as well as feeling the effects of burning skin, stinging, heavily watering eyes, and burning mucous membranes.

CN grenades like the M-7A1 are primarily used by the military, as they are much too powerful for use in riot control (CN can actually kill victims with compromised respiratory systems, such as those with asthma). It should be noted that the first sign a victim may have of CN gas is a brief burst of an apple blossom-type smell.

Notes: This grenade, the bane of US military basic trainees and rioters alike, is a grenade containing CS irritant gas. It is similar to the M-18 colored smoke grenade, but is a hazardous weapon that burns very hot as it discharges its gas, often producing fire in combustible materials it lands on, and many buildings have been set on fire when this grenade was thrown into the building by police during hostage situations. An adapter exists to use this grenade as a rifle grenade. The M-7A3 actively produces a gas cloud for 12 phases (60 seconds). It was superseded by the non-flammable M-25A2, but hundreds of thousands exist in military and police arsenals.

Notes: This is a bursting-type WP smoke grenade, able to be used for signaling, screening, to destroy flammable objects, and produce casualties. Due to the inherent danger, it was replaced for smoke purposes by the M-18 and ANM-8, and was replaced for destroying things by the ANM-14 and as an antipersonnel weapon by the more stable M-34. Many other countries had stocks of them, and they were also re-issued or never went out of use there. The smoke from this grenade builds and disperses rapidly, and only one phase of thin smoke is produced when the grenade is triggered.

Twilight 2000 Notes: The M-15 was retained in storage, and was re-issued in the Twilight War starting in late 1996.

Notes: The cloud of smoke produced by this grenade depends on the chemicals included and can be red, green, yellow, or violet (the famous "purple haze"). A colored band on the grenade indicates the smoke color. The M-18 produces very little heat, and can actually be held in a gloved hand during and after detonation (detonation merely ruptures a small hole in the base).

Notes: Grenades containing incapacitating agents such as CS or CN are used for riot control or in situations where prisoners need to be taken.

Notes: The M-26A1 replaced the Mk2 as standard fragmentation grenade with US forces and most of her allies. The M-26A2 is similar, but has a contact fuse that explodes when it hits its target.

Nicknamed "Willie Peter" from its initials, this grenade scatters fragments of burning white phosphorus throughout its burst radius, producing a dense cloud of smoke and igniting any combustibles in the area. The Geneva Accords of

1928 prohibit the use of this grenade against personnel, a restriction usually ignored in the heat of battle.

Notes: This grenade was designed to be about the size and shape of a baseball. A (probably apocryphal) story states that the grenade was made this way on the assumption that "every red-blooded American boy knows how to throw a baseball," and training would be much easier. It is slightly lighter than the M-26A1 (and slightly heavier than a baseball). The M-68 is similar, but uses a fuse that causes the grenade to explode on impact instead of after a delay.

Notes: Initially designed as a training device, US special operations personnel quickly discovered that it could also be used as a flash-bang type of grenade, and it quickly became one of the first of these devices used by US and NATO forces. The Kilgore/Schermuly grenade is shaped similar to the M-26A1 fragmentation grenade, but the body is plastic and in the interior is a paper-wrapped pyrotechnic device which produces the flash-bang effects. The blast produces a 175-decibel bang as well as a 1-million-candlepower flash of light, which produce 24 combat phases of disorientation when used in an enclosed area, or 8 phases if used in an open area. This disorientation follows the standard rules presented in Merc 2000. Being an early flash-bang grenade, it has a number of defects which were partially or totally solved by later grenades: The fuze mechanism has a highly-variable delay (0.7-3 seconds) which is not controllable by the thrower, and the flash can ignite combustibles within a 1-meter radius (20% chance), including the paper within the grenade.

Notes: The Mk 1 is an illumination hand grenade, consisting of an egg-shaped body with a central band, and containing a magnesium mix that produces intense light and heat when it bursts. The fuze delay is a full 7 seconds; it will thus go off in the middle of the combat phase after which it is thrown. The Mk 1 Mod 2 produces a 55,000-candlepower flaring light for 25 seconds (5 combat phases); it bursts suddenly and the light extinguishes quickly after the 25 seconds of burn time. The grenade burning is hot and may ignite combustibles within 3 meters of the burst area. There were three Mods of the Mk 1 produced, Mod 1, 2, and 3; Mod 1 and 2 differ primarily in the fuze used, with the fuze on the Mod 2 being a much simpler affair. The Mod 3 version is the same as the Mod 2 except that the Mod 3 uses two plastic shell halves instead of steel. All three Mods are still in stock and used by SEALs and other special operations units.

Notes: Known as the "pineapple" due to its notched-body design, this WWII-vintage fragmentation grenade can still be found in some armories. A nearly identical grenade, the Mills Bomb, was the standard British grenade during WWII, and a Soviet design, the F-1, is also similar. It was discovered that the notches in the grenade body had nothing to do with fragment size and merely led to unpredictable fragment dispersion, and this led to its withdrawal.

Notes: This is a concussion grenade. They are less lethal than fragmentation grenades (in the sense that their lethality radius is smaller) and are used by hostage rescue teams and in urban combat situations where close-quarters fighting is likely.

Notes: Though the ANM-14 thermite grenade was quite effective at destroying materiel and generally starting fires, the SEALs discovered in Vietnam that it was inadequate for killing personnel or starting fires on wet substances. To this end, China Lake developed the Model 308-1 Napalm Grenade. It was essentially an ANM-8-type grenade body filled with napalm and gasoline, and modified to accept a different fuze, producing a small napalm bomb. It was made in small numbers, and usually issued as a kit, allowing the SEALs to vary the mix of gasoline and napalm. (The statistics below are for an average sort of mix.) Objects and personnel caught in the burst radius of a Model 308-1 suffer effects similar to those of being hit by a flamethrower with regards to whether they burn and the damage they take. If the person carrying the Model 308-1 is hit by gunfire or fragments, there is a 1 in 20 chance per such grenade carried that one of them will explode, with all the possible secondary effects.

The fuze delay of the Model 308-1 is an entire combat phase, to help ensure that the thrower and his friends don’t get caught in the burst area. The burning time of the napalm in the Model 308-1 is one minute.

Notes: The HAAG (Hand Anti-Armor Grenade) is a rare example of a Soviet weapon being "reverse-engineered" by the US. It is an improved version of the Soviet RPG-43 (a predecessor of the RKG-3). The XM-78 was produced as an experiment and is quite rare.
