Which of the following is a Warrant Officer rank lower than CW5?

• A. Warrant Officer 1
• B. Warrant Officer 3
• C. Warrant Officer 4
• D. Warrant Officer 2

Answer: (C)

Warrant Officers come in four levels, from WO1 up to WO4, while Chief Warrant Officers go from CW2 to CW5. CW5 sits above all Warrant Officer ranks. Among the Warrant Officer ranks, the one closest to the Chief Warrant Officer tier is WO4. So WO4 is a Warrant Officer rank that is lower than CW5, and it best illustrates the relationship between the two groups. The other options—WO1, WO2, and WO3—are also below CW5, but they are more junior and less representative of the level just below the Chief Warrant Officers.
