This is coolbert:

Yet one more uniformed branch of the U.S government until recently I was not aware of.

"National Oceanic and Atmospheric Administration Commissioned Officer Corps"

As with the Public Health Service consists strictly of those of officer rank. No enlisted personnel or warrant ranks.

"The National Oceanic and Atmospheric Administration Commissioned Officer Corps, known informally as the NOAA Corps, is one of eight federal uniformed services of the United States, and operates under the National Oceanic and Atmospheric Administration (NOAA), a scientific agency overseen by the Department of Commerce. The NOAA Corps is made up of scientifically and technically trained officers. The NOAA Corps and the United States Public Health Service Commissioned Corps are the only U.S. uniformed services that consist only of commissioned officers, with no enlisted or warrant officer ranks."

"NOAA Corps officers can be militarized by the President of the United States under the provisions of 33 U.S.C. § 3061"

Mission and duty of NOAA:

"The National Oceanic and Atmospheric Administration is a Washington, D.C.–based scientific and regulatory agency within the United States."
