Your very correct it's much more effective online and by the way I'm seeing alot more smoke users in socom3 than there were in 2, probably due to the larger area the smoke covers. I usually carry 2 sets of smokes and they add no load at all. For offline I wouldn't advise using smoke because with the CPU AI the whole smoke distraction probably won't work, you can try. Although if it does attract their attention it would proove useful when trying to sneak past enemies like in missions that it is suggested that you don't engage at all. For single player what should work with smokes is to provide cover for snipers.
great work guys,now everyone knows these tactics.so when people like me want to use tactics we have come up with,everyone will know them and will slaughter us on the field.
