Whatever else you say about the Army’s Warrant Officer program prior to 1970, one thing is certain: For a time, its officers had some of the most unattractive rank insignia ever created. In 1956, seven years after Congress approved the creation of four Warrant Officers grades, the Army unveiled a rank insignia scheme that evokes adjectives such as “baffling” and “bewildering.” It seems to have been inspired upon the Commissioned Officer rank insignia system where the lowest officers in the two Non-General Officer categories, Company- and Field-Grade, would each have insignia of gold (2LT and Major) while the higher-ranking officers in each group would have insignia of silver. At the very least, it wasn’t very intuitive for a Chief Warrant Officer 4 to have five bands of alternating brown and silver.

In 1970, a new system of Warrant Officer ranks insignia was approved, with all ranks having insignia in the same two colors (silver and black), and a design that almost instantaneously informs the viewer of the rank. A WO1’s rank insignia had one single black square, a CW2’s two, and so forth.
At the same time this pleasant change was made, the Army was considering introducing two grades of Warrant Officers, CW5 and CW6, and went ahead and designed rank insignia for them. The CW5 insignia developed then is the same as the one used today, but unfortunately for Chief Warrant Officers 4 the new grade was no implemented at that time. That would come in 1991, when the pay grade of W5 and a rank called Master Warrant Officer CW5 was established; it was later renamed Chief Warrant Officer 5.
