first off, i don't watch the show and strongly dislike it, to put it nicely. secondly, that doesn't counter my reason for being against it. its not how the CIS works. they would have simply blockaded and jammed it, and moved in on Kamino.
Actually E if you even watched the episode you must've missed 90-100% of it for it was mentioned
Why the CIS had Commandos and sent them in to secure the post...
The place was transmitting an all-clear signal through the Republic's comm channels. So if the CIS simply blockaded the place, Jammed the signal, and decided to go in and take it in a mass attack... The republic would have found out about the attack before the CIS had a chance to land their troops, and would have sent a task force to the base and another one to Kamino. Thus why the CIS would make them.
Also an addition to the Variable Vocabulator... If you have seen the episode you would have seen in two instances of its usefulness. One was of when Rex and Cody arrived in system one of the droids used a clone's helmet and the vocabulator to make itself sound like a clone. And again when Rex and Cody arrived when another commando was put in some clone trooper armor and tried to get them to leave.
Also the CIS did infact didn't stick with cheaper droids if you've noticed in the cartoon, books, games, and Movies.
Episode 1: the introduction to Vulture droids, B1s, and Droidekas Episode 2: the CIS begins use of larger more heavily armored B2s, and Dwarf Spider droids.
Episode 3: the introduction of Magnaguards, Crabdroids, Buzz Droids, and the Octuptarra Tri-droids.
Heavy Metal Jedi: Introduction to the rancor-sized B3s
If the CIS could afford these in large numbers I am sure they could afford a B1 Battle Droid modified(with tougher armor and a new vocabulator) for Covert OPs.
Whomever said that the commando droids were "another example of Lucasarts ruining Star Wars" if you haven't realised this is a TV show/movie produced from the mind of George himself.
I myself am for Droid Commandos as they could spice up the playing experience.
