Wraith grenades are egg-shaped explosive devices used by Wraith warriors.
Description[]
When twisted and armed, they set off a timer, resulting in detonation after several seconds. They can also be used as pressure sensitive mines, though it's unclear if this is a standard feature or just an unconventional use of their triggering mechanism, as only Major John Sheppard was seen using them this way. The weapon is somewhat out of character for the Wraith, as it has the potential to damage valuable "food". They seem to be used primarily to damage structures. (SGA: "The Defiant One", "The Siege, Part 3")
At least one Wraith hunter was seen carrying several of these when he was chasing Ronon Dex on P3M-736, indicating that the Wraith may also use these when hunting for runners, although this does not appear to be a common usage. (SGA: "Runner")
Notes[]
- It's not made clear how Sheppard was able to determine that the grenades could also be used as pressure sensitive mines, given he never encountered them before. In the scene where he activates the first grenade, the grenade's lights glow red and emit a high pitch sound, which seems to indicate indicate arming, which remain constant as long as he squeezes the grenade. The blinking countdown only starts after he moves the grenade. It's possible Sheppard must have realized that as long as the grenade stays restless after arming, the timer doesn't activate.
