So after spending numorus days getting the bronze stars, and not getting the insignia i went for silver stars thinking there was one for getting all weapon silver stars too and seeing if maybe my stats screwed up as why i was not getting the bronze star one.
after getting all silver after, i noticed there was no insiginia for doing that lol. so then i googled and i guess it is the M1 screwing up getting the bronze star insignia so everyone thinks.
as lots of other have all bronze and nothing on M1
So if your wasting your time like i did dont feel bad when you dont yours either.
hopefully its fixed soon
