The M84 device is best described as which type of grenade?

• A. M7A2 CS/Tear Gas
• B. M84 Stun Grenade
• C. Fragmentation Grenades
• D. M18 Smoke Grenade

Answer: (B)

Understanding how flash-bang stun grenades work and how they differ from other grenade types is what this item tests. The M84 is designed to momentarily disorient and stun targets with a bright flash and a loud noise, without producing fragmentation that could injure people in the vicinity. This non-fragmentation behavior is what makes it a stun grenade.

Because it relies on a brief, intense blast of light and sound rather than chemicals or shrapnel, it is used to gain control of a doorway or room during entry or to create a temporary distraction. In contrast, a tear gas device releases CS irritant gas to incapacitate through chemical exposure, which is a different mechanism and has its own risks and limitations. A fragmentation grenade is designed to project shrapnel over a distance, causing injuries, which is not the intended purpose of the M84. A smoke grenade produces dense smoke for concealment or signaling, but it does not provide the focal, disorienting flash and bang of a stun grenade.

So, the M84 is best described as a stun grenade.
