It's smoke grenades this time in this Golandec Airsoft video... "Look how thick the smoke can come from one airsoft smoke signal. For the first time it began to be used actively on games airsoft smoke grenades (smoke bombs), I made a conclusion that it is very convenient and useful piece with no wind. :)

Excellent work on the approach to the building before you go under the building unnoticed, to throw on both sides of the two smoke bombs, and after half a minute to run up and begin to storm the building.

For myself saw such a thing, that before to throw smoke, you need to hand trotted grenade so that it better start to smoke. For when it falls, it could immediately envelope in smoke nearly everything."
