“Quite a few years ago (late eighties) a SEAL was tossing a grenade, the fuse had been changed out for instantaneous detonation”

Why would an instantaneous detonation fuse be made to fit a hand grenade?

Why would an instantaneous detonation fuse be made to fit a hand grenade?

For use as a booby-trap, removing the 4-5 sec delay, one of the "old ways" was to insert smoke grenade fuses which had an almost instantaneous firing train... set up a trip line, pull the pin, boom.

Haven't kept track of the newer devices as they have gotten smaller, so I don't know if they can have or even accept different types of fuses.

Guess they still do have some "short fused" devices running around... and still causing problems... “We were training with Afgan privates using prototype smoke grenades. The intent of the grenade is to set-off a smoke screen for sniper fire. Some of the grenades have short fuses. Mine was a short fuse but it wasn’t marked.”
