Commando Droid
Commando droids are an elite model of battle droid used by the Confederacy of Independent Systems for special operations.
Features
Commando droids are stronger, faster, and more heavily armored than B1 Battle droids. They are not as strong or durable as B2 Super Battle Droids, but they are more agile.
Commando droids are substantially more intelligent than most other battle droids, making them far more dangerous. They are far less common, however, presumably due to the expense of the superior AI.
