I was thinking about the non-pyro grenade issue, as that is a incredible omission of a tactical tool in the way milsims are played. Unfortunately, I don't have any good answers to that problem.
However, as grenades can not only be tossed, but rigged with trip wires to form a trap I was reminded of this gadget.
Or likewise, here.
Basically, a device that when a trip wire is pulled it activates a glowstick.
There would certainly be no bang, but the light given off would show that the trap had been sprung. Rules could be decided beforehand for the effective radius of the "explosive."
Or do people already use these and I'm just a newbie. :grin:
