If you're referring to Phasma, then as a general rule of thumb you should ignore her military rank. According to SW literature, although she's technically a captain, her true position in the First Order is much higher (more or less on the same level as Hux & Klyo Ren).
***EDITORS*** All the Star Trek Discovery Season 0 ("Short Treks") episodes here are MISNUMBERED. According to IMDb, s0e01 is Runaway, s0e02 is Calypso, s0e03 is the just-released Brightest Star; s0e04 won't be out until Jan. The links HERE for "01" are correct, but are the same as for "02" (or mostly so?--I didn't look at all of them), "03" are for the real 02, and "04" are for the real 03. Some other sites are making the same mistakes.

This sexy, sleek drama takes viewers into the lives of a group of husbands, wives and friends that live and love in the same middle class neighborhood. On the surface they are true-to-life, relatable people – raising children, working jobs, finding and maintaining romance - but just below the veneer of happiness, their lives are entangled by heartbreak, deceit and lies that threaten to destroy everything.
