Collarinsignia Seaman apprentice is the second lowest enlisted rate in the U.S. Navy, U.S. Coast Guard, and the U.S.
(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.
No stripes are worn on the working uniforms - coveralls or utilities.
