### Description of the bug

USCM squad specific beret was black, instead of what was shown in the character creation menu

### What's the difference with what should have happened?

Black Beret, rather than a fully red beret

This is what it shows you would get. And instead, in game it is entirely black (I did not have a screenshot for this)


### How do we reproduce this bug?

1. Make character with loadout points in squad specific beret
2. Become alpha rifleman
3. Watch as you have a beret that is nothing like what your loadout screen suggested you'd get
