United States Public Health Service Commissioned Corps

The United States Public Health Service Commissioned Corps (PHSCC) is the federal uniformed service of the United States Public Health Service (PHS) and is one of the seven uniformed services of the United States.

The Public Health Service Commissioned Corps is one of two uniformed services that only consist of commissioned officers and has no enlisted or warrant officer ranks, although warrant officers have been authorized for use within the service. Officers of the PHS are classified as noncombatants, unless directed to serve as part of the armed forces by the President or detailed to a service branch of the armed forces. Members of the PHSCC wear the same uniforms as the United States Navy with special corps insignia, and hold ranks equivalent to those of naval officers. Officers of the PHSCC receive their commissions through the PHSCC's direct commissioning program.
