Warrant officer (United States) in the context of "Chuck Yeager"

The United States Public Health Service Commissioned Corps (USPHSCC; also referred to as the Commissioned Corps of the United States Public Health Service) is the uniformed service branch of the United States Public Health Service and one of the eight uniformed services of the United States (along with the Army, Navy, Marine Corps, Coast Guard, Air Force, Space Force, and NOAA Commissioned Officer Corps). The commissioned corps' primary mission is the protection, promotion, and advancement of health and safety of the general public.

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. Officers of the commissioned corps are classified as noncombatants, unless directed to serve as part of the military by the president or detailed to a service branch of the military. Members of the commissioned corps wear uniforms modeled after the United States Navy and the United States Coast Guard, with special Public Health Service Commissioned Corps insignia, and hold naval ranks equivalent to officers of the Navy and Coast Guard, along with corresponding in-service medical titles. Commissioned corps officers typically receive their commissions through the commissioned corps's direct commissioning program.

The National Oceanic and Atmospheric Administration Commissioned Officer Corps (informally 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. The NOAA Corps' primary mission is to monitor oceanic conditions, support major waterways, and monitor atmospheric conditions.

The NOAA Corps traces its origins to the establishment of the United States Coast and Geodetic Survey Corps on May 22, 1917, which the service recognizes as its official date of establishment. The Coast and Geodetic Survey Corps became the Environmental Science Services Administration Corps in 1965, which in turn became the NOAA Corps in 1970.

Henry Knox (July 25, 1750 – October 25, 1806) was an American military officer, politician, bookseller, and a Founding Father of the United States. Knox, born in Boston, became a senior general of the Continental Army during the Revolutionary War, serving as chief of artillery in all of George Washington's campaigns. Following the war, he oversaw the War Department under the Articles of Confederation from 1785 to 1789. Washington appointed him the nation's first Secretary of War, a position which he held from 1789 to 1794. He is well known today as the namesake of Fort Knox in Kentucky, which is often conflated with the adjacent United States Bullion Depository.

Knox was born and raised in Boston where he owned and operated a bookstore, cultivating an interest in military history and joining a local artillery company. He was also on the scene of the 1770 Boston Massacre. He was barely 25 when the Revolutionary War broke out in 1775, but he engineered the transport of what became the "noble train of artillery", British ordnance captured from Fort Ticonderoga in New York, which proved decisive in the British evacuation of Boston in early 1776. Knox quickly rose to become the chief artillery officer of the Continental Army. In this role, he accompanied Washington on all of his campaigns and was engaged in the major actions of the war. He established training centers for artillerymen and manufacturing facilities for weaponry that were valuable assets in winning the war for independence.
