The EG coloured smoke grenades emit ~10000 cu.ft. of smoke. For about two dollars extra, the Sport Smoke Tactical line does ~25000 cu.ft. I find anything less than 20000 cu.ft. doesn't provide enough cover for anything... but the small output of the EG line has purposes. I've used them to mark targets on a field and my line lit up the location, dealing with bunkered enemies. Hosts can use them to mark objectives in the field as well.
