IMO infantry smoke is excessive, although there's an item at lonesentry.com which indicates German infantry, at least, had smoke grenades and "candles." There's also a discussion at theminiaturespage.com which suggests other grunts had it. Maybe you can use the editor to tone it down a bit.

I recall reading accounts of German and British tanks using smoke in David Irving's The Trail of the Fox and Stuart Hills' By Tank Into Normandy. You can Google "tank smoke shells ww2" for a little more info, but there doesn't seem to be a whole lot.
