This was necessary to hide the creation of the clone army from the rest of the galaxy. Known as the Cuy’val Dar, “those who no longer exist” in the Mandalorian language, these warriors discarded their old lives to train the commandos in secret. Moreover, the commandos were trained by a group of 100 warriors, 75 of whom were Mandalorians, hand-picked by Jango Fett. Whereas standard clones were trained extensively with simulators to save on costs, commandos were more often trained with live fire to familiarize them with battlefield conditions. They ate, slept, and trained together to think of themselves as part of a unit rather than an individual. The Kaminoan cloners modeled the commando squad structure after the aiwhas, grouping them into squads of four and training them together from birth. The water planet of Kamino is home to the aiwhas, winged whale-like creatures who hunted in pods. This made them adept to the specialized training regimen that they were put through. However, unlike their rank and file brothers, the commandos were genetically engineered to be stronger, smarter, and deadlier while still remaining highly obedient to their Kaminoan cloners and Jedi commanders.

Like all clones, commandos were based on the genetic template of the legendary bounty hunter, Jango Fett.
