Nowadays i know that almost all armoured vehicles (tanks, armoured personnel carriers etc.) carry on their turrets small tubes, usually bunched up in threes, to launch smoke in front of them so other tanks, anti tank soldiers etc. cant see them if they need to pull out if damaged, or the crew need to bail out etc u get the point. I was wondering if these smoke grenades/launchers were present on the armoured vehicles during ww2, and if so they could be fitted to give an even more tactical element to the gameplay.
