ive been thinking about adding a commanders gun to the top of his (i think its cupola, not too sure) and it would rotate as he looked around and the guy would be holding it in the turned out mode, this would definately work, and about marsuitor's post, if you look at the t72 model in oxygen you will see the definitions 'otochlaven' and 'otocvez' otochlaven controls vertical rotation of a gun and otocvez is the horizontal rotation, you cant have 'otochlaven2' or something to define a second rotation for a gun, so having the nsv move wouldnt work, while looking at the t72 model if you switch to the memory lod you will find a vertice with the selection 'kulas' this is basically why this discussion happened, because people have seen that tank guns can fire from two different spots, but all it is is a single vertice, which is attached to the main rotation, now while writing this ive just had an idea...if you put it at the end of the commanders gun and grouped it to the commanders rotation then it would spin round as the commander looked and he would 'aim' it,then if he used manual fire he would be able to fire it, the commanders turret has no vertical rotation so it would only be able to shoot at things on the same level as it, but it is a way of getting a commander to shoot....
