      For use with trip wires or as a booby traps. Most grenades are designed to use a variety of fuzes.

      This article has an example.

      From my experience most incendiary grenades don’t have a time delay either. They’re meat to be put on an item for destruction, pin pulled, and then leave. We used to set them off remotely by placing a blasting cap under the spoon after pulling the pin and taping down the spoon.

      Generally, a grenade that explodes immediately with no delay would be useful for trapping an area. I can’t think of any other uses off the top of my head. It could also have been an old or incorrectly installed fuse in the grenade.

      Not advice

      Think of a doorway of an indoor area. Take the grenade, hold the lever, pull the safety pin, and slip it into a tin can. Wedge the can somewhere near the doorway out of sight. The can holds the lever in place which keeps the primer from igniting the fuse. Now tie some clear fishing line to the grenade itself and make a trip wire across the doorway low to the ground. Now, if the wire gets kicked, it pulls the grenade out of the can and it instantly explodes rather than a 3~5 second delay.
