Hi all, it seems to me that sub-machine guns never fire a round. I made several checks with the german MP-40 (same Estab values as for the american's, but fires a different ammo from rifle and MGs) and the figure for ammo never gets reduced, unless randomly when some losses occur. I think it has something to do with the extremely short range of the weapons (<150m) and the low precision. However this happens in any terrain, even where SMGs were the most effective weapons (say urban, industrial...Stalingrad). Engagement ranges are almost always within 100-150m (measured front to front of opposing units) whereas in such dense environments I would say that should be a few tens of meters.
