During the time of the Galactic Civil War, Dors Urtya, the regent ruling Mon Cala, made use of individual protectors. When the Alliance to Restore the Republic embarked on a mission to secretly convene with him, Urtya opted to forgo the presence of his protectors, as he didn't desire any casualties if danger arose.
Following the initial unsuccessful effort to convince Urtya and Mon Cala to align with the rebellion, the Rebel Alliance launched a subsequent endeavor to sway the Mon Calamari towards joining the Alliance through the liberation of King Lee-Char from the clutches of the Galactic Empire. Despite Lee-Char's demise at the hands of Imperial troops during this operation, Leia Organa and her team managed to capture King Lee-Char's dying declaration.
Once their deception at the Moncaladrome was uncovered, Urtya sent for his protectors, who then joined him as he obtained the recording from Organa. These protectors consisted of Mon Calamaris outfitted in unique armor that included weaponry, along with a specific model of droid.
