And I'm eager to finally release this sometime.
Regarding the Colour Sjt sub-class idea, which is a new unit in the Infantry-tab regiment. It seems 6 *ranks* being Ranker, Ensign, Colour Serjeant, Officer, Drummer, Fifer is great and works as intended but there is an annoying side-effect being the Glengarry Light Infantryman unit moved to the end of selectable Voltigeur Canadiens. Then when I click on the Light Infantryman unit it brings the highlighted regiment to GLI section and moves the 1 Player notification of which regiment you have selected from Voltigeurs to GLI.
So tl;dr back to the drawing board on this one.
Without the presentations for rank_6 the new class appears but the fifer is out of the picture in the menu, literally.
Trying this again.
