I wondering if you still get a unlock when ranking up to a First sergeant.
You should. I'm pretty sure. Why?
Well on the UBAR ranking it said that Master Sergeant has the Unlock available, but since I have all the basic badges for First Sergeant I was curious since it doesn't say unlock available for first sergeant and only the awards you needed.
Oh, I see. Probably just a typo. You still get an unlock. I remember I had the "advanced" rank from having all the badges and still got one.
