Seaman apprentice
military rank

Seaman apprentice is the second lowest enlisted rate in the U.S. Navy, U.S. Coast Guard, and the U.S. Naval Sea Cadet Corps just above seaman recruit and below seaman; this rank was formerly known as seaman second class.
The current rank of seaman apprentice should not be confused with the rank of apprentice seaman which was the lowest Navy rank from 1904 to 1948. In the old system apprentice seaman was followed by seaman 2nd class and seaman 1st class. (The three tiered rank system for seamen dates from the 18th Century Royal Navy when the ranks were called landsman, ordinary seaman and able seaman.)
The actual title for an E-2 in the U.S. Navy varies based on the community to which the sailor belongs. Likewise, the color of their group rate marks also depends on their community.
Those in the general deck and administrative community are seamen apprentice (SA). They wear white stripes on navy blue uniforms, and navy blue (black) stripes on white uniforms.
Hospital corpsmen are hospital apprentice (HA). They are the only rate in this community. They wear white stripes on navy blue uniforms, and navy blue stripes on white uniforms.

Why this record matters
The phrase “military rank” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jul 18, 2026. The linked authority identifier is Q16961535. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1904 and 1948.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
