I'm a former US Army Infantry Officer. The Balmorals label Ariborne Maroon or SF Green are just a marketing thing. I do not believe that there is a register color for Airborne Maroon or SF Green. In the US market words like Airborne and Special Forces are used all the time to sell things that often have nothing to do with the individual that are have to earned their wings or the militrary units they serve in. IMHO Dark Green, Bottle Green, Rifle Green don't have the same marketing value as SF Green in the US. It is simply a way for the shops and manufactures to identify the color to the US market. Some day I may own a Dark Green or a Maroon Balmoral but I would not describe them as being SF or Airborne just Green or Maroon.
