Heh, as soon as I woke up this morning I was thinking how I called it USAF... and totally saw that coming! Thanks for not disappointing
It's interesting though, I've been noticing the slightly different markings as I build these things but never paid it much thought.
I read most of that link you gave, but I'm still a bit confused. Is the National Insignia common to all the various groups, but some other markings are specific?
As always thanks for the backstory! I learn as I build.
