The rank of petty officer meant that they were in charge of supervising the deck crew or any ships onboard. A petty officer is essentially a Private that serves in the Republic Navy. The only known trooper to possess the rank is Bren, who served on the Leveler.
The trooper was present during the Mission to JanFathal. He was under the command of Captain Gilad Pellaeon, a high ranking non-clone official of the Republic Navy. He survived the battle, and likely went on to fight during the Battles of Merson and Gaftikar.
