The True Mandalorians were a Mandalorian group of supercommandos who remained loyal to Jaster Mereel, their leader and the reigning Mand'alor, when Mereel's reformist ideals for the Mandalorians were met with opposition from Tor Vizsla's radical splinter group known as the Death Watch. Assembled from the standing full-time army of the planet Mandalore, and a number of prominent Mandalorian clans, the True Mandalorians were a highly organized and skilled group of soldiers whose moral code put them in heated opposition to the Death Watch. They were followers of the Supercommando Codex, and the True Mandalorians believed in Jaster Mereel's ideals for a Mandalorian culture in which honor and decency was valued over the barbarism and brigandage favored by Death Watch.
