In 60 BBY Mandalore Jaster Mereel issued his Supercommando Codex. Jaster's men served as mercenaries and warriors for hire, but their primary goal was to hunt the Death Watch. During the Mandalorian Civil War, the Supercommandos loyal to Mereel's True Mandalorian faction were eliminated to the last man at the 44 BBY Battle of Galidraan.
Decades later, during the Clone Wars, Mandalore the Resurrector trained two hundred and fourteen new recruits as Supercommandos, although by the end of the war all but three (Mandalore, Fenn Shysa, and Tobbi Dala) were dead. It is unknown if Shysa's later Mandalorian Protectors used the term.
By the time of the Second Galactic Civil War in 40 ABY, Mandalore Boba Fett had a total of one hundred Supercommandos to call on including Fett's granddaughter Mirta Gev, her fiancé Ghes Orade, Orade's adoptive father Novoc Vevut, Baltan Carid, Ram Zerimar and Goran Beviin.
During the Second Battle of Fondor, Fett led a group of fifty Supercommandos allied with Admiral Natasi Daala aboard the Imperial-class Star Destroyer Bloodfin to retake the ship from forces loyal to the Moffs attempting to join forces with Darth Caedus. The Commandos succeeded, although they were forced to allow Sith apprentice Tahiri Veila to escape with aid from Caedus due to Fett's orders that only Jaina Solo could confront her brother.
