Warrant officer (United Kingdom)

In the British Armed Forces, a warrant officer (WO) is a non-commissioned officer (NCO) holding a warrant from the Crown. Warrant officers are not commissioned officers, but occupy a unique position within the NCO ranks. They are superior to all other NCOs, but subordinate to commissioned officers.

The warrant officer rank exists in all three branches of the UK Armed Forces: the Royal Navy, the British Army, and the Royal Air Force. Within each branch, there are typically two classes of warrant officer: Warrant Officer Class 1 (WO1) and Warrant Officer Class 2 (WO2). Some specialized roles, such as Queen's Gurkha Officer in the Brigade of Gurkhas, may have specific warrant officer ranks and titles.

The roles and responsibilities of warrant officers vary depending on their branch and specialisation. Generally, they serve as subject matter experts, advisors, and disciplinarians, providing leadership, mentorship, and technical expertise to both officers and other ranks. They often hold positions of significant responsibility, such as regimental sergeant major (RSM) in the Army, or master-at-arms in the Royal Navy.

Appointment to warrant officer is earned through years of service, demonstrated leadership potential, and the successful completion of advanced training courses. Warrant officers are highly respected and are essential to the effective functioning of the British Armed Forces.

Pay and allowances for warrant officers are significantly higher than those of other NCOs, reflecting their increased responsibilities and expertise. They also have access to enhanced accommodation and other benefits. The rank is a career goal for many NCOs seeking to advance within their chosen service.
