The ethics officier didn't seem very trustworthy to me. You report to him that his subordinates blow up refugees for fun and basically all he does is say: "What they haven't stopped doing that after I already told them to stop it? Okay. I'll tell them to stop again."
Oh, that's also a good point... You have soldiers basically murdering civilians by making them run a minefield for supplies, and all the ethics officer does is tell them to stop? There should have been tribunals investigating who was involved, then handing out severe punishments. But the local military must be heavily corrupt - while covering up a few of these crimes by blaming them on the separatists probably works you'd need very highly ranked people to keep the lid on it for so long and so many crimes.
