This mod replaces the USAF Flight Jacket with the Royal Showstopper Suit (Yes, pun intended).
This includes both the icons and the localization files.

Supports all the characters, however some pants might clip but that's a very minor thing. I spent 7-8 hours on this and I am really proud of it.
It also works Online!

Installation Notes:
Drop the folder with the mod from the archive to your mod_overrides folder, if you don't have it then you need to create one.

Example Path:
E:\Steam\steamapps\common\RAID World War II\assets\mod_overrides

Requires RAID WWII BLT

Enjoy.
