After my wife and I first viewed Rogue One we both walked away and mutually we had one question hanging around. What are these two stick/sword things hanging from Jyn's back?
To my recollection, she never uses them in the film so as a prop-piece it seemed like an odd thing to have put on a costume. This made my wife and I speculate that something must have been cut from the film that would have explained their purpose.
Further details that might be spoilers:
I am aware that she's wearing this outfit because she and the other rebels have taken out a few Imperial troopers and that they are wearing their uniforms as disguise. She appears to be wearing a gunner's uniform, though I'm not 100% sure that is what the outfit is. I assume this could be part of the uniform. Regardless, I see no example of a gunner wearing these devices, so I'm not sure that she is, in fact, wearing a gunner's outfit.
My main problem is that I've never seen these devices before, nor do I recall seeing their use in the movie.
So... what are they?
