hmmmm.....well the problem with that is that by changing the skins in game it will not only alter your unit but it will alter all the units that use that uniform due to the way N&S is set up 1 uniform (hat, pants, shirt) could be used on all sorts of different units in all sorts of combinations.
Now, I think a thread should be made where regiments leave their reg name, what they want (what uniform), and an image of the uniform so that for the next update if we choose to even add new uniforms we can see what the public would like to see.
ALSO
I have made a new troops file which has many the bug fixes / new units (DOSE NOT REPLACE ANY OLD UNITS ONLY ADDS)
In order to get it message 1stDE_TheDoctor on steam or wait for me to release a full thread explaining it and having a link for it.
I could rename an existing unit for you to your regiments so name just pick a unit (find a unit that looks the most like them), or in the new update (if approved by the others and if they server at the beginning of the civil war) I might be able to assemble the unit with new or current items in the mod.
