This is a Brazilian Air Force (FAB) livery using the HAVEGLASS style of coating. Thanks to Yae Sakura and M A C H 3 D S for helping me in the Livery Art Group discord.
You'll encounter 4 different bort numbers within the file for this livery. 4618, 4627, 4644, 4659.
Brazil does not, and never has, bought or employed the F-16C. This livery is purely fictional and made for fun.
UPDATE: I noticed the wrong roundel on the left wing and corrected it.
