im not sure if this is the correct forum to ask this but today i took out my great grandfathers WWII navy uniform. Its black with no insignia or other markings except for a golden eagle inside of a gold cirle on the upper portion of your right chest. I've searched all over the internet and have come up empty handed on what the symbol means and the significance of the black uniform. Previously my uncle back in the early 70's tried to find out information on what he did and it was classified. Does anyone know the significance to this uniform and/or the insignia?
