Smoke "spotting"

[joe_oppenheimer]

The rules for the use of smoke state " So a 12-turn game allows for two rounds of smoke/illumination, while a 36-turn game would allow four turns. To track usage, place either a Smoke or Illumination marker under the firing unit to indicate one usage, or note off-board artillery's usage on a piece of paper". It would seem that "rounds" would mean only 2 smoke firings in a 12-turn game, whereas "turns" would imply that all units capable of firing smoke rounds could each fire smoke in a given turn, and do so for one other turn. Should this be two rounds fired in a 12-turn game, or e.g. 6 rounds fired in two separate turns if one had three 16 OBA?

I've always played that it's one use of smoke or illumination per ten turns.

I recently played a 22 turn night scenario from Black Panthers. When the American tanks closed with the German held town German officers called in star shells three times to give a nearby 88 a chance to shoot at the tanks.
