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 (literally 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.
