US Warrant Officers are neither Officers nor NCOs
Candidates who successfully complete Warrant Officer Candidate School are appointed in the grade of Warrant Officer One. When promoted to Chief Warrant Officer Two, warrant officers are commissioned by the President and have the same legal status as their traditional commissioned officer counterparts. However, warrant officers remain single-specialty officers whose career track is oriented towards progressing within their career field rather than focusing on increased levels of command and staff duty positions.
They operate, maintain, administer, and manage the Army‘s equipment, support activities, and technical systems. WOs are competent and confident warriors, innovative integrators of emerging technologies, dynamic teachers, and developers of specialized teams of Soldiers. Their extensive professional experience and technical knowledge qualifies warrant officers as invaluable role models and mentors for junior officers and NCOs.”
