Note that, unlike the woman in the center, they are wearing male uniforms and insignia (shoulder boards and collar patches); the uniform of the one on the right is even badged for an Unteroffizier (and appears to be several sizes too large). Also, her hairdo and shoes are not what I would expect to see worn by an auxiliary on duty.
Even if there was a shortage of female uniforms necessitating them to be issued ill-fitting, hand-me-down male uniforms, I would at least expect the rank insignia to be removed.
I suspect there's a story there which we will never know.
I am speculating here, but could it be that they were kitted out like this - plus helmets - in the hope of blending in with a mass of soldiers (note the many man in the background) to avoid rape? Or were the outfits staged for the photograph and if so, why?
Us and them - and after all we’re only ordinary men. Me, and you - God only knows it’s not what we would choose to do. Forward he cried from the rear, and the front rank died, and the general sat and the lines on the map moved from side to side.

Note the narrow "political" shoulder boards as worn by the NSKK as well as the type of his breast eagle: Judging from its outlines and its dark backing, I would say this is an NSKK sleeve eagle with the scroll on top removed.
