where's the Army?
I'm not sure if you know it or not but all of those with the exception of the Navy are trademarked. The "Hap Arnold Wings" are not being licensed at all and are strictly only used in Pentagon approved material. The Marine Corps not only trademarked the EGA but ALL terms associated with the Corps such as Semper Fi, USMC, Marines and United States Marine Corps. It is quite expensive to get licensed and all products need to be approved prior to putting them on the market. If the Blank maker is licensed you are covered...if not you can get into legal trouble making and selling them.
Just a heads up!
