Lucasfilm has been kind enough to provide us with another clip of the upcoming episode of The Clone Wars.
This is from the third and penultimate episode in the Umbara arc.
From the press release:
The battle for Umbara continues in “Plan of Dissent,” a new episode of Star Wars: The Clone Wars, airing at 8:00 p.m. ET/PT Friday, November 11th on Cartoon Network.
After the Republic conquers an Umbaran airbase, General Krell orders Rex and his men on towards the heavily fortified capital. Realizing there’s a better plan, several clone troopers disobey orders to carry out a rogue, covert operation.
