In the United States military, a [Warrant] Officer (grade W-1 to W-5) is ranked as an officer above the senior-most enlisted ranks, as well as officer cadets and candidates, but below the officer grade of O-1. Warrant officers are highly skilled, single-track specialty officers, and while the ranks are [authorized] by Congress, each branch of the Uniformed Services [selects], manages, and utilizes [warrant] officers in slightly different ways. For appointment to Warrant Officer One (W-1), a warrant is approved by the secretary of the service. Chief Warrant Officers ([W-2] to W-5) are commissioned by the President of the United States, and take the same oath as regular commissioned officers (O-1 to O-10).
Warrant officers can and do command detachments, units, activities, vessels, aircraft, and armored vehicles as well as lead, coach, train, and counsel subordinates. However, the [Warrant Officers] primary task as a leader is to serve as a technical expert, providing valuable skills, guidance, and expertise to commanders and organizations in their particular field.
