E-4 to E-6 are considered to be
non-commissioned officers (NCOs), and are specifically called
petty officers in the Coast Guard. Their sleeve insignia is a perched eagle with spread wings (also referred to as a "crow") atop a
rating mark (a symbol denoting their job category), with red
chevron(s) denoting their relative rank below. The Coast Guard does not follow the Navy's practice of awarding gold chevrons for twelve years of good conduct, rather all petty officer rank chevrons and service hash marks are red, whereas gold is reserved for chief petty officers. However, the rank insignia worn on collars have yellow chevrons. Onboard
cutters, the first class petty officers become members of the First Class
Mess which serves as a recognition of their status at the top of the junior enlisted ranks. This manifests itself on small cutters as a few reserved tables in the
galley, but may be a separate seating area or space on board a large cutter. The food is the same as that in the galley from which the other junior ranks eat. It also is a precursor to the Chief's mess. All ranks from petty officer third class and above (Including warrant and commissioned officers) also have the ability to perform an arrest while on duty. ==E-7 to E-9==
