In general, officer ranks are those used in the Prussian and pre-1945 German armies. Officer rank insignia are worn on shoulder straps or shoulder boards. Army ("Heer") and air force ("Luftwaffe") junior officers' insignia are four pointed silver stars while field grade officers wear silver (black or white on camouflage uniforms) stars and an oak wreath around the lowest star. The stars and wreath are gold for general officers. In the case of naval ("Marine") officers, rank is indicated by gold stripes on the lower sleeve of the blue service jacket and on shoulder boards of the white uniform.
