|There is more information available on this subject at 40mm grenade on the English Wikipedia.|
The 40mm grenade has two detonation modes, depending upon the way it is detonated after firing. The first detonation mode, upon being fired, bounces off a surface once, or when it strikes an organic target, will detonate almost immediately, causing an instant kill. The second detonation mode results in a delayed detonation, usually when the user takes their finger off the trigger after holding it down for a time. Additionally, the grenade is capable of emitting an electromagnetic pulse, so when detonated in close proximity to a mechanical target, like a Wraith, a Ghost, or a Revenant, the targeted vehicle will power down temporarily.
