What is the fuse delay of the M84 stun grenade?

• A. 1.0 -2.3 second fuse delay
• B. 0.1 - 0.3 second fuse delay
• C. 3.0 - 4.0 seconds
• D. 5.0 - 6.0 seconds

Answer: (A)

Fuse timing is the interval between arming the device and detonation, and for the M84 stun grenade that window is designed to be brief but allows the operator to move to a safe position before the flash and bang. The typical fuse delay is about 1.0 to 2.3 seconds after activation. This duration balances giving the operator a moment to retreat and ensuring the device explodes at a moment that maximizes disruption while minimizing risk to the operator. Delays much shorter would feel almost immediate and reduce the operator’s safety margin, while delays much longer would unnecessarily extend exposure and complicate control of the situation. So the 1.0–2.3 second range best fits the device’s purpose and design.
