I have to ask this question,how do I get the UN small flag icon on my profile?

Go to the Milforum PX (link at the top), and go into the "other Flags and Custom Gear" shop.
It costs 50 MilBucks there..

Darn,I don't have 50 milibucks!!! I only have 25 bucks!But I want that UN flag.... Thanks for the help...
