Artillery smoke availability

[chuckfourth]

Hello
It seems all in-game off map and on-map aritllery can fire smoke. However probably half or more of these guns didnt have a smoke round. As an example look at http://www.tarrif.net/ This site only shows smoke for the German 105mm standard divisional field piece, one of the 150mm guns and the 120mm mortar. Leaving the German 75mm, 77mm, 17cm, 21cm guns and 81mm mortar all without smoke, which they do have in-game.
It would seem sensible that the smaller guns wouldn't have a smoke round as these small shells wouldnt produce much smoke. The larger calibre corps type artillery, usually 15cm and up wouldnt have smoke rounds either as they dont conduct this sort of fire mission. Corps artillery fire missions are typically counterbattery, interdiction or targets deep in the enemy rear ie smoke not required. Also the chain of command is longer to the corps weapons. Laying of smoke normally needs to be coordinated with an infantry advance and so we would want a good direct link with the units firing, ie using our "own" divisions guns
For on-board artillery, this site lists these weapons as not having smoke rounds. Youll need to sign in to see it.

Russian 50mm Mortar
Italian brixia Mortar
German 5cm Mortar
German 75mm infantry gun
Japanese 70mm infantry gun.
in-game they have smoke.
Also from a russian site currently offline, see
http://www.battlefield.ru/guns/project_4.html
http://www.battlefield.ru/guns/project_1.html
http://www.battlefield.ru/guns/project_2.html
But when they were up they show no smoke for the Russian guns calibres 122mm, 152mm 210mm and 280mm
Some other points,
Rocket units in the game can fire smoke. As far as I can make out smoke rockets actually weren't made (nebelwerferfer may be the exception). This makes sense to me as Rockets lack accuraccy, a prerequisite for smoke delivery.
I think currently smoke persistence is related to visibility? Actually I think it should be related to wind speed. As wind speed is not modelled in the game then maybe the value of smoke persistence should be random rather than related to visibility?
Happy to supply a list of which guns did and did not have a smoke round of course.
Maybe it would be possible for off board artillery to have a total of say 80 shells and fire them as either smoke or HE as required? ie can fire 80 HE or 80 smoke.
