What is the correct designation for a W-2 rank?

The correct designation for a W-2 rank is Chief Warrant Officer Two. This rank is part of the warrant officer classification in the U.S. Coast Guard and other branches of the military, which denotes a level of expertise and technical skill in a specific field. A W-2 rank signifies an individual who has advanced beyond the entry-level Chief Warrant Officer One and possesses a certain amount of experience and additional responsibilities.

Each warrant officer rank, such as W-1 and W-3, represents a different tier in terms of experience, knowledge, and leadership capability. Warrant officers are typically appointed for their specialized skills and are critical to the functioning of military operations.

The other options refer to ranks that either do not correspond with the W-2 designation or are ranks at different levels within the military structure. Therefore, Chief Warrant Officer Two accurately reflects the W-2 ranking and its associated responsibilities within the Coast Guard.
