Just for part of the interest and conversation not just on this product but...
I love the idea of innovations and realism, but lets just look at the game we play going back say two years or so.
flash bangs, distraction devises, grenades etc. all have there place in the "real" world for sure, re enactments or specialized training they would be a must. but first for safety sake, anything that go's boom, snap crackle or pop has to be deemed safe in a "controlled" situation, again seriously, could you see giving a hand full of those things to a group of noobs nuf said.
we have been using smoke canisters for years now, I could count on one hand how many times they have been used effectively! cool to pop and through but most sit out in the middle of know where with the wind blowing the smoke in the wrong direction
people could be trained but when was the last time we saw all players call their hits, wear a kill rag and know what the game rules are! but were still running around shooting at people and these people are training every week for months!
but yes it would be cool to be able to toss a device that was safe, made some noise and presented a definite kill with in a radius when it went off that people had to honor as a kill.
