These were provisional officer rank pins. The angular bars in the middle denoted the corresponding rank,
- one bar=ensign
- one bar+one dark bar=lt. jg
- two bars=lt
- two bars+one dark bar=lt.cmdr
- three bars=cmdr
- four bars=captain.
These were given to the Maquis crew when they were merged into Voyager's crew by Captain Janeway and Chakotay. Chakotay's rank pins indicate Lt.Cmdr but he served in the billet and capacity as a full Cmdr.
