| Flag Officer |
Ŝiparadmiralego | Fleet Admiral |
 |
A Flag Office is generally a
"desk job", although generally only Commodores find themselves in the
actual combat theatre.
The rank of Fleet Admiral exists only during major wars, and its holder has
absolute authority over the entire navy, subject only to the Emperor
himself. |

Every ship and boat with a crew
of at least ten men must have a single Captain, and at least one
Commander. The Captain's Unulo (First Officer) is most often the
single Commander on the vessel, although this is not a set rule, and a First
Officer may be of any rank below Captain. |

Recruit |
New recruits (during basic training) would wear
no uniform insignia, since they have no uniform (they customarily go through
training naked (for conditioning, hazing, and team-building purposes—and,
yes, studies actually have shown that the overall esprit d'corps
is improved this way). |
