. A warrant officer is an officer who can and does command, carry out military justice actions and sits on both selection and promotion boards. A US warrant officer is a single-track specialty officer, initially appointed by their respective service secretary; he/she receives a commission upon promotion to chief warrant officer two (CW2). In the UK the separation between "other" ranks and "officer" ranks can, on occasion, become permeable. Within the British armed services, both Sir Fitzroy Maclean and

are examples of, rare, rapid career progression with the British army, both rising from the rank of private to brigadier during World War II. In the US military such advancement is not uncommon, all five services maintaining programs that select promising enlisted men and women for the commissioned ranks.

US "Enlisted" and UK "Other ranks" compared

UK and US ranks are categorised in the NATO rank code system OR-1 to OR-9. Ranks with the same code are not necessarily equivalent however. Within the US military, however, "E-1" to "E-9" is the more common usage. Notes on comparison: *In the US Army OR-1 to OR-4 (specialist) are junior enlisted, OR-4 (corporal) to OR-6 are junior non-commissioned officers (NCOs), and OR-7 to OR-9 are senior non-commissioned officers (SNCOs). *In the USAF OR-1 to OR-4 are junior enlisted, OR-5 to OR-6 are NCOs, and OR-7 to OR-9 are SNCOs. *In the USMC, OR-1 to OR-3 are junior enlisted, OR-4 to OR-5 are NCOs, and OR-6 to OR-9 are staff non-commissioned officers. *In the US Navy and Coast Guard, OR-1 to OR-3 or "nonrated (wo)men" are junior enlisted, OR-4 to OR-6 or petty officers are NCOs, and OR-7 to OR-9 or chief petty officers are SNCOs. *In the British Army OR-1 to OR-2 are junior enlisted, OR-3 to OR-4 are junior NCO's, and OR-5 to OR-9 are SNCO's *Generally speaking, the RN assumes a rank up despite the NATO code remaining the same. For example, a LH is more practically comparable to a PO2 or PO1 in the USN. *While in the British Army a lance corporal is the next rank up from a private, unlike in the US Army they are considered junior NCO's, and hold a similar command appointment to a US Army sergeant. Because of this it is not unheard of for lance corporals to be given US Army sergeant rank insignia when serving with US forces. *While there are different pay-grades for privates (and other enlisted ranks) in the British Army, these are tied to job-role (MOS) rather than time in service. As such there is no promotion from a class 4 private to a class 3 private, nor are there differing badges of rank. Addendum: In the US Army (but not the USMC) the term "trooper/(troop)" may be used informally for lower enlisted in cavalry, scout, airborne, air assault, Ranger, and Special Forces units, along with the occasional use for any soldier, particularly dismounted infantry. The specific definition of "troop" is a company-sized unit of cavalry, organizationally equivalent to "battery" in artillery units.

warrant officer
in UK service is a senior non-commissioned rank not comparable to the various grades of warrant officer in the US, although holding the Queen's Warrant and with certain privileges similar to those of officers. In the Army and Royal Marines, they are referred to by their appointment, of which there are many (for example,

is a WO1 appointment). The US rank is held by single-track career specialists (ranking between enlisted ranks and 2nd lieutenant) and have no NATO equivalent. A RN warrant officer class 1 incorporated the former rank of fleet chief petty officer. There are now executive warrant officers, denoting the senior WO1s on ships and shore establishments. The Command Warrant Officers have been removed under the Royal Navy Command Transformation Programme. The most senior Royal Navy WO1 is the Warrant Officer of the Naval Service (WONS) The rating of WO2 in the Royal Navy was removed in 2014 but reinstated in 2021. The recent senior Warrant Officer of the British Army is the "Army Sergeant Major". In November 2018, the highest Warrant Officer/OR position was created, namely the

. * RAF Flight Sergeants: Although technically equivalent to British Army Staff Sergeant this does not equate to time served or experience since the RAF does not have the rank of WO2. * The RN created the rate of Warrant Officer Class 2 on 1 April 2004. Previously, there was a rate of Charge Chief Petty Officer, who usually ranked as OR-7, although above other CPOs. A Charge Chief Artificer (a highly qualified technical CCPO) could be given a NATO OR-8 status, but still ranked below WO2 in the Army and Royal Marines. On the creation of WO2, all CCPOs were upgraded to this rate.NFF – Naval Families Federation
/ref> * In the US "OR #" system, NCOs are from OR4 onwards hence the equivalents in rank name do not tie in exactly. In the US Army a Corporal is considered an NCO, but a Specialist is not. * British Sergeants/Petty Officers are seen as equal to E5 ''and'' E6 although Corporals ''as well as'' Sergeants may be appointed to an official OR-5 (i.e. E-5) military role as is suited to the particular situation. * From April 1, 1999, the Able Rating and Ordinary Rating of the Royal Navy merged and called Able Rating, the grades of Marine 1st Class and Marine 2nd Class of the Royal Marines merged, and Junior Rating and Junior Marine were abolished. * Technical trades and musicians only. ''Promotion'' to the rank of Junior Technician ceased in 2005, only to be replaced by Senior Aircraftman (Technician) a short time later. * The most senior WO1s are, in descending order, the

This gives them more authority on the ground, as well as a better pay band.

The introduction of L/Cpl rank put this on a more formal footing, and eased the minds of many enlisted soldiers from other units who were unhappy being commanded by individuals they perceived as no higher ranked than themselves. * In the
