Flag of an unknown United Balkan nation/alliance from Call of Duty: Modern Warfare
from /r/vexillology Top comment: This flag can be very faintly seen on the arm patch of the "Balkan ATU" mil-sim character skin in COD: Modern Warfare, and I did my best to re-create it here. It is unknown if this is a country, alliance, economic union or other form of union between the Balkan nations, and no information on this region's political affairs in the COD Universe is provided in the game. EDIT: I couldn't tell if the islands off the coast of Greece and Croatia were on the patch or not due to how small it is on the character, but I assumed it would be best to include them.
