I thought I would try some Sport Smoke Tactical Airsoft - Paintball Smoke Grenades (TSG) and show you how they work out in an open area and also when in an enclosed area (indoors). These Tactical Smoke Grenades put out a lot of smoke but will require either a non windy day or an area where the smoke can accumulate to give you good coverage. Either way they do a greta job of causing a distraction that will allow you to get into a better position.
