I spent some time and made a few British line infantry rank icons for starters.
Firstly I may consider doing different historical rank icons for various different companies and countries. I will base the scheme of the colour of the units and the colours they have on their shoulder plates.
Secondly, I'll try and put time into these icons so they're usable and I'll be making a British company pack, with the same base of rank to keep it simple, and it will be helpful for armies etc that have the many detachments and so on.
Note: The icons will sit in the middle section of the 1st page, under thread designs.
I will come to a conclusion over the coming weeks to come up with other icons to change the shape of the rank icon base, to either make it smaller or larger. For anyone who takes interest or would like to use them because they couldn't find any of their own, then feel free to use them. If you wish, you can comment down on which icons you're using.
