I'll try again.  The leggings look much different from those I remember.  And there are no rating badges.  When did those appear?  And (gasp!) no hearing or eye protection, although they might have cotton balls stuffed in their ears.

It is difficult to tell for sure, but are these African American sailors?  The closest could be and the next closest appears to be.  Could be shadows. I ask because I thought that African Americans were limited to non combat roles. Just to be clear, I believe that was wrong no matter the time in history. I'm just trying to put the photograph in historical perspective. Would non combat sailors be trained to shoot a rifle?
