Marshal (Portuguese: Marechal) is the highest rank in both the Brazilian Army and the Brazilian Air Force, although the latter is titled marechal-do-ar (lit. 'marshal of the air'). These ranks are equivalent to that of admiral in the navy. A marshal is distinguished by using five stars, which for a marshal of the air are in the approximate position of Southern Cross and for a marshal in the army, in the form of "X". The five stars of admiral are in the shape of a pentagon.
