<P> The SMA's cap device, worn on the front of the blue service cap (and, formerly, the white service cap; and, until 2011 the green service cap) is a gold - colored rendering of the United States' coat of arms, surrounded by a wreath . The cap device for all other U.S. Army enlisted soldiers is a gold - colored rendering of the United States' coat of arms on a gold - colored disk (males) or surrounded by a gold colored ring (females). The chief master sergeant of the Air Force has the same cap device as the SMA, but in silver - colored metal . </P> <P> The Sergeant Major of the Army, Chief Master Sergeant of the Air Force and the Senior Enlisted Advisor to the Chairman are the only members of the United States armed forces below the rank of brigadier general / rear admiral, lower half to be authorized a positional color (flag). First considered in 1992, the SMA's color has been authorized since 22 March 1999 . It is based on the design of his collar insignia and the positional flag of the Chief of Staff, Army . Like the SEAC's collar brass, the SEAC's positional color was patterned after the SMA's color . </P> <Table> <Tr> <Th> #</Th> <Th> Photo </Th> <Th> SMA </Th> <Th> Tenure </Th> </Tr> <Tr> <Td> 1 . </Td> <Td> </Td> <Td> William O.
