Ok, some answers to the various topics mentioned in the few last posts...
Asuser: you are right... things are a bit "overloaded" now, and I sometimes try to make much in little time... This is not a good recipe for making quality work... So lets put that Konig Tiger in the freeze for awhile and focus in the previous work. I was asking because I do not like very much the look of the stock game icon for that tank (specially the turret, the hull I guess is ok). You are rifgt also about the modern Do-24... something looked different about those wing tips! You are like an eagle!
Also, thanks for the nice words about the Flamm Hetzer!
Rezaf: No problem with people posting stuff here... The only thing I ask anybody here is to be repecful and friendly to the other users. Graphics, technical/doctrinal data, etc... any knowledge is always welcomed. I am a perpetual learner of Second World War stuff...
T2_2112: Thanks for the pictures, they can be useful. But, I don't like very much the looks of that Porsche turret front armor and gun mantlet... The big pictures are beautiful, on the other hand!
Uhu: The main concept I imagined for the direct fire versions of Wespe, Hummel, and all SP artillery in general is not to go with those vehicles in a tank hunting happy hour (a low enough initiative value, plus the low armor values of those units should make that tactic suicidal), but to be used, in an emergency, as direct fire assault guns against fixed targets (like fortifications) and infantry, and also in a desesperate self-defense scenario... It would be great if sometime in the future, fortifications could be "discriminated" from tanks and other armoured vehicles by introdicing a new category of target: "Fort" or maybe "Structure"... With the same idea, units would add a new attack value... "fort attack". This way units with heavy, hard hitting guns could be very effective against forts but not against tanks, a good example of this could be the mentioned Sp Arty, and of course, railroad guns.
For example, US forces used the "Long Tom" self-propelled 155 mm guns in direct fire against the Siegfried line fortifications, and the soviets used heavy SP and towed artillery in direct fire mode when attacking Berlin,as it was already mentioned.
That adition would be nice, because tanks and field fortifications are very different kind of targets indeed.
Having checked my main reference book (Encyclopedia of World war Two German tanks by Camberlain, Doyle and Jentz) all of the three mentioned vehicles (Wespe, Hummel, sIG 38(t) could depress their guns to zero degrees, but it is not mentioned if the guns could be fired when in that position, but I asume that they could...
Stan23: Some new and original bunker units are in the working, by Asuser and also by me. The Flak bunkers, for example are sitting from a long time ago in my "to do" list. Expect some news in the not so distant future. If I am not mistaken, in the "Afrika Korps" mod made by the DMP modding team, there was a unit that switched into an airfield...
About Flamm Hetzer: Asuser, Horst, Nikivdd, Stan23... Thanks guys for the nice words! This is the "fuel" that makes the icon-converter machine go on "turbo-mode"
I appreciate you a lot, friends, and I am very glad to help modders and gamers to improve this gaming experience!!!
Asuser: It is true, my friend the idea was taken from some Puma icons I downloaded... By the way, the smoke plume should look familiar to you... as it was "borrowed" from your very nice german locomotive icons (BR50 and BR52)
I could not help to "recycle" things!
where might I find it
