The Warrant Office Ranks

A warrant officer possesses skills that make them the adaptive technical expert, combat leader, trainer, and advisor. Through progressive levels of expertise in assignments, training, and education, the warrant officer administers, manages, maintains, operates and integrates systems and equipment across the full spectrum of operations.

The warrant officer is a former enlisted that has decided that the commissioned officer ranks are not for them and that their skills will allow them to better interface between the enlisted ranks and the commissioned officer ranks.  They are truly an unique breed of service members.

Neither the United States Air Force (currently) nor United States Space Force have Warrant Officers.

As a result of a study to improve the warrant officer insignia of grade to make it easier to identify the grade, new insignia was approved by the Chief of Staff Army on June 10, 1970 with an effective date for wear of July1, 1972. Based on anticipated change in legislation to authorize two additional warrant grades, new insignia for W5 and W6 were also approved by the Chief of Staff in 1970. The insignia was developed but never authorized for wear for W5 and W6.

With passage of the Warrant Officer Management Act on December 5, 1991,the grade of CW5 was established. On March 28, 1991, the Chief of Staff approved continued use of the Master Warrant Officer insignia for Chief Warrant Officer W5.
