Thanks so much for the mod. It's annoying how few insignias have been added by Paradox so mods like these are a god send. If you need more British/Commonwealth insignia; this site has pretty much everything covered http://www.petergh.f2s.com/flashes.html
I don't know if you're able to add theatre icons but it would be nice to have the 21st and 15th Army Groups as a theatre icons and maybe the likes of AFHQ, SHAEF and SACSEA icons for the Brits and US. The base game offers one for the British which sucks big time.Thanks again.
