Enlisted rates
All warrant and commissioned officer ranks had the same names as their army counterparts. For seamen and petty officers, which were selected from enlisted men or conscripts and given one year of training in the Navy PO Academy, the naming changed in 1942. Both of the names were different from the army names but were equal in rank.

Service branch colors
The branch of the Navy in which non-executive personnel served was indicated by a color code. For officers, including midshipmen, it was the color of cloth placed as background to the cuff stripes, on both sides of the gold lace on the shoulder boards, and as longitudinal piping on the collar patches. Midshipmen and cadets wore a colored anchor on the cap, which cadets wore on the shoulder boards as well.[2] The branch of enlisted men was denoted by the color of the Chrysanthemum flower on their rank patch; line personnel using the default gold.
