I've found a very minor issue, but I love this period so much and this game looks so awesome that I'd like to help make it even more perfect!
I've noticed that in every HQ unit there's an element called like "Hospital", "Lazaret" or "Médicale"...despite that the element is always something different from a real Field Hospital...for French it's a heavy artillery, while for the Allies it's usually an engineer or pioneer element. Please check the attached screenshot.
I suppose that at some point the Medical Service ability was moved to the HQ element itself, but the names didn't change. Also, please notice that in the same screenshot the Engineer element has a "Transmission" name...
