Which rank corresponds to E-3 in the Fireman category of the US Coast Guard?

The Fireman Apprentice (FA) rank corresponds to E-2, while the Fireman (FN) rank aligns with E-3 in the Fireman category of the US Coast Guard. An E-3 rank signifies that the individual has completed certain training and has achieved a level of experience that qualifies them for this designation. The rank of Fireman includes responsibilities that require a solid understanding of operational procedures and gives the individual the ability to assist in various firefighting and engineering tasks aboard a vessel.

The other ranks—Fireman Apprentice (E-2), Seaman (E-3, but in a different category), and Seaman Apprentice (E-1)—do not fit the E-3 designation within the Fireman category. Therefore, Fireman, being an E-3 rank, is the most accurate choice when looking for the corresponding rank in that specific category.
