PHSCC.

This is coolbert:

"Along with the NOAA Commissioned Officer Corps, the Public Health Service Commissioned Corps is one of two uniformed services that consist only of commissioned officers and has no enlisted or warrant officer ranks, although warrant officers have been authorized for use within the service"

Until just a short time ago was not aware the United States has eight uniformed services. Consider:

"United States Public Health Service Commissioned Corps"

"The United States Public Health Service Commissioned Corps (US PHSCC), also referred to as the Commissioned Corps of the United States Public Health Service, is the uniformed service branch of the U.S. Public Health Service (PHS) and one of the eight uniformed services of the United States alongside the United States Army, Navy, Marine Corps, Coast Guard, Air Force, Space Force, and the NOAA Corps. The commissioned corps' primary mission is the protection, promotion, and advancement of health and safety of the general public."

"According to 5 U.S.C. § 8331, service in the U.S. Public Health Service Commissioned Corps after June 30, 1960, is considered military service for retirement purposes. Under 42 U.S.C. § 213, active service in the U.S. Public Health Service Commissioned Corps is considered active military service for the purposes of most veterans' benefits and for anti-discrimination laws."

Public health service has their own decorations and are encouraged to wear military dress. Serve with titles of military rank.

Public health service even having a Presidential Unit Citation award. Distinct and unique decoration not to be confused with the Presidential Unit Citation as is awarded to the conventional war-making military services.

"On 24 September 2015, President Barack Obama presented the Presidential Unit Citation to the officers of the United States Public Health Service Commissioned Corps for the 2013–2016 Ebola epidemic in West Africa and the United States. On 19 January 2021, President Donald Trump presented the citation to all Commissioned Corps officers serving from 2020 to 2021, for their extraordinary performance of duty during the COVID-19 pandemic.

Only officers, no enlisted or warrants. Who waxes and buffs the floors?
