about commandos

A clone commando, or Republic commando, was an elite soldier of the Grand Army of the Republic. Often working in groups of four, clone commandos were assigned to carry out covert operations too delicate for regular clone troopers. Covert infiltration, sabotage, foreign unit training, and assassination were standard tasks for the clone commandos.[1]

When Order 66 was issued by Emperor Palpatine at the end of the Clone Wars, one commando unit, Ion Team, refused to fire on their commanding Jedi for various reasons, and several other commandos deserted, thus showing that at least some commandos were independent.[2]
