I've known them to be called "Yellow Shirts", not yellow jackets.... I've been on a couple aircraft carriers and have never heard the term, and I've also been around alot of other countries special combat arms and never heard the term....
No, that's "Yellow Jackets". The term was used in the Air Force but I can't remember wich country.
There is three possibilities...
1 - An Elite Squadron
2 - A term to designate the "Reccon." pilots
3 - A second term to designate a rookie pilot (knowing that they're called "Green" in English and "Blue" in French).
