I guess this is just an addendum really, but I've been watching some of the Clone Wars series. I've just got as far as Season 2, Episode 5, where the Republic forces invade Genosha (sp?).
In this, I learned that this was a planet they had previously already invaded, that the people there had managed to kick them off and so they were re-invading a second time to re-establish their control. Things that stood out to me - a Jedi Master had the troopers use flame-throwers on the native defenders (you get to see them burning as they roll around on the ground), Anakin and Asoka have a good-natured competition in how many of their enemy they kill (note, there are some droids in this one but most of the enemy seem to be living beings and the ones that the third Jedi master who wins the competition was fighting all were). Large parts of the defender's city are visibly destroyed including a massive tower at the centre of their city. Also the Jedi are "surprised" at the Genoshans (sp?) loyalty to Count Dooku.
Anyway, the episode ended with the Jedi comparing kill-tallies and Republic occupation of the planet re-established. I keep looking for subtext or self-awareness. I thought the third Jedi Master's comment about "so what do I win?" was going to be some sort of spiritual commentary on treating the deaths of others as sport, but it seemed not to be after all. Much more of this and you can sign me up for the Dark Side.
EDIT: Also, is it me or were the Genoshans in the caves unarmed? As far as I can see they were fighting bare-handed unlike the ones on the battlefield who mostly had guns bar the odd one swooping down. Does that means that the ones hiding in the caves away from the battle were just the civillans / evacuees? I mean they appeared to have no defences and the Jedi were only there because they got lost and had to take an unexpected path through the mountains. So there was no military purpose to the Genoshans being there - they seemed to be just hiding out until the Republic Forces blundered in.
