Design
Design
The M84 features a pyrotechnic metal-oxidant mix of magnesium and ammonium nitrate inside a thin aluminium case, contained within a perforated cast steel body. Unlike the high explosives (HE) used in traditional ordnance, the pyrotechnic charge produces a subsonic deflagration, not a supersonic detonation, minimizing the blast effects. On initiation, the auditory and visual elements of the deflagration are permitted to escape via the perforations in the cast outer body. This design minimizes the risk of collateral damage due to flame, blast, and unconsumed fragments of the inner case. Upon deflagration, it emits an intensely loud "bang" of 170–180 decibels and a blinding flash of 4.5 million candelas within 5 ft of initiation, sufficient to cause immediate flash blindness, deafness, tinnitus, and inner ear disturbance. Exposed personnel experience disorientation, confusion and loss of coordination and balance. While these effects are all intended to be temporary, there is risk of permanent injury. Consequently, the M84 is classified as a less-lethal weapon. It is intended to be thrown into enclosed spaces to distract and temporarily incapacitate enemy personnel for easier capture, or when risk of collateral damage during urban warfare or hostage rescue operations contravenes the employment of traditionally lethal and destructive fragmenting high explosive ordnance. While the M84 is generally incapable of igniting paper or cloth, it can still ignite extremely flammable liquids or vapors (such as concentrated gasoline or ether fumes) in the immediate area of the grenade.
Adoption
Adoption
US Army doctrine calls for the M84 to be deployed "during building and room clearing operations, when the presence of noncombatants is likely or expected and the assault element is attempting to achieve surprise."

U.S. Marine Corps Lance Cpl. Thomas Echols uses some down time to clean his weapon as his fellow Marines establish a command post in Ramadi, Iraq, on Oct. 29, 2006. Echols is attached to the 1st Battalion, 6th Marine Regiment.
