Chaff grenades are a miniature chaff dispenser.
Operation and function
Chaff consists of small aluminum strips that are specifically designed to confuse radar frequencies, and normally used by aircraft to fool missile radar. The individual strips are cut in such a way that they wreak havoc with radar's transmitted frequencies. The chaff grenade is a combination of a wide-dispersal system for such strips and an electronic jamming system similar in effect to a magnetic pulse; it fools most electronic devices in the current room, including security cameras, radios, and some types of UAV.

Solid Snake managed to procure some chaff grenades while sneaking on board the U.S.S. Discovery tanker to take photographs of the Metal Gear RAY prototype. Two years later, Raiden managed to procure some, and used them to fight the Metal Gear RAYs guarding Arsenal Gear, as their weapons systems were not adapted to be anti-personnel.
Behind the scenes
Chaff grenades first appear in Metal Gear Solid. Along with disabling electonic equipment, they can also interfere with radio signals and prevent enemies from calling in reinforcements temporarily. In addition, the Chaff Grenades are also the only weapons capable of damaging Gray Fox. If they are used during the fistfight portion of the boss fight against Gray Fox, the latter, in addition to being damaged, will also chastise Snake for fighting cheaply, and then attempt to cut down Snake with his sword. In Metal Gear Solid 3: Snake Eater, chaff grenades are implied to be of Soviet origin, and can be used to disrupt Colonel Volgin's electrical field during Naked Snake's battle against him. If the player detonates a chaff grenade in front of TNT or radios, the red lights on each of them will start to flash rainbow colors. Something similar occurs in Metal Gear Solid: Portable Ops. It weighs 0.8 kg during the 1960s.
Metal Gear Solid 4: Guns of the Patriots
Chaff grenades are a very limited and a hard-to-find weapon in Metal Gear Solid 4. They can be found in 5 locations in the game:
- Act 1, Advent Palace escape. Equip a chaff grenade (assuming this is a continued play) and stand in front of Akiba/Johnny. He will throw out two of them.
- Act 2, Confinement Facility, in the middle house. A tip is to take the left road after blowing up the Power Station, then go back to the right after you reach the Salt Hills. This will save you some time and effort.
- Act 2, Marketplace. Equip rations, then stand in front of the last Gekko at the fence. Head directly left behind a stall. (You can shoot down the Gekko first.)
- Act 3, When you get to the area with the searchlights (above the sewers) turn north and open up the map. The chaff grenades are in the top-left area between a bench and a plant.
- Act 4, Helipad. In an act of nostalgia, they are located at the center of the helipad, the same spot where they were found when Snake first infiltrated the Shadow Moses facility.
Chaff grenades can be used to confuse Scarab unmanned weapons, though they are less effective against Gekko. The design of the chaff grenades in Metal Gear Solid 4 are based on a grenade-shaped gas bottle for Airsoft guns. The "M363" marking is actually the code for an obsolete canister round for tank cannons.
Metal Gear Rising: Revengeance
The Chaff grenades were split into separate grenade types that emphasized certain characteristics of chaff grenades. One of these was the EMP Grenade, which, besides having the properties of stun grenades for cyborgs, also temporarily disabled unmanned gears. The other was called the jamming grenade, which prevented radio transmissions from being sent or received by enemy cyborgs.
In-game weapon descriptions
- "A electronics jamming grenade developed by the Soviet Union. Upon detonation, scatters a large quantity of metal fragments into the air, jamming radio signals and rendering electronic devices inoperative."
- ―Chaff grenade description in Metal Gear Solid 3: Snake Eater
- "A non-lethal grenade that temporarily disables any electronic devices in the area by releasing a cloud of signal-jamming metal fragments upon detonation."
- ―Chaff grenade description in Metal Gear Solid: Portable Ops
- "A non-lethal weapon that scatters a cloud of metal strips when detonated, scrambling nearby electronic devices. When surrounded by unmanned weapons, a chaff grenade can turn the tables in an instant. The chaff can also temporarily block the user's own radio and sensor signals, so these grenades are best saved for when the time is right."
- ―Chaff grenade description in Metal Gear Solid: Peace Walker
- "A disposable EA [electronic attack] device that employs an internal battery to barrage jam a wide range of frequencies. Capable of cutting off communications of most any wavelength, as well as temporarily disabling remote-controlled UGs."
