Yes they did have smoke grenades in WWII. They had a whole assortment of grenades.
Fragmentation, concussion, smoke, white phosphorous (nasty stuff! I would burn holes into your skin).
Smoke would have been a nice addition. I would have also loved to have seen a real dark night mission where you have to hold a line of defence and use flares to see the enemy coming. It would have been fun running around in a trench or manning a .30cal on one of the outposts.
