I was playing a Scenario game of like 125 V 125 and soem guy threw a smoke in this village area and it really mixed things up but we just had our automatic men fire into it and our RPG men fire there stuff in there and just threw paint grenades when they got to any bunker near us didnt work for them but it was one of the highlights of the day it was talked about for hours. I mean sure it doesnt help your team but wouldnt you wanna be the guy saying, "Bro I threw that smoke grenade".
Anywho I get all my smoke grenades at my local grocery store But i looked this site up just for you
For all of your tactical smoke grenade training needs!
