Erusean 156th Tactical Fighter Wing 'Yellow Squadron' (Su-27)

Based on the Ace Combat 7 version of Yellow 13's livery.

Includes 3 skins
- Blank/Custom Board Number
- Yellow 13
- Yellow 4

***WARNING***

The Yellow 13 and Yellow 4 skins use relative paths to reuse shared textures from the blank/custom board number skin to help reduce file size, so the "roy_yellow" skin folder must be present if either are in use
