How is the rank of Chief Warrant Officer 4 denoted?

The rank of Chief Warrant Officer 4 is denoted as W-4. In the military's rank structure, each warrant officer rank is assigned a specific numeric designation, where the "W" stands for warrant officer, and the number denotes the specific rank level. Therefore, W-4 indicates that the officer is in the fourth tier of the warrant officer rank system.

This rank signifies a high level of technical expertise and leadership, typically achieved after several years of service and demonstrated proficiency in a specialized field. Each warrant officer rank, from W-1 to W-5, corresponds to increasing levels of responsibility and experience, but Chief Warrant Officer 4 specifically indicates this fourth level.
