i completed this quest as an apprentice carbine specialist. took out the two (or three, i dont remember) white con selonians, and then the blue, and didnt have much problem taking out the red con leader. no reward for this quest.                                      

Sorry if I'm asking a stupid question, but I was just curious as to who is the bad guy in this situation.  Are the Selonians enemies of the Rebel Alliance or allied with them? Or are they just against the corrupt Imperial governors ruling Corellia. If they are against the Empire or the corrupt government then I'll help them out, because from what I remember Thracken Sal-Solo is a real @#%^, and I wouldn't be surprised if he was working for the Empire or the corrupt government. If either one of these are the case, let me know by posting to this message, and I'll surely help out the Selonians and Thracken can kiss my ass.

I completed the fourth part with being a Master Unarmed Specialist and had two friends one being a novice Bounty Hunter and the other being a novice ranger.  I took out the four Selonian Sentinels before they arrived and together we took out the Selonian Leader. He was a white con to the three of us in a group, he was red to me alone.

or, become a leader of a group, go in that area, and tell your group 2 attack it.(its fun to trick your best friends into doing your dirty work)
