What advice would you have for someone whose command has retaliated against him for making an IG complaint?

If you have concrete proof file a Congressional with an influential Senator or Congressman. Make sure you do your homework on the person/people you are filing this against.

"Stop being a window licker and get rid of social media."

You should re-phrase the question if you want to get some good COAs. This is too general. First thing I'd like to know is the type of retaliation. With the way you posed the question I'd want to know when the individual is eligible to PCS from the unit and does HRC know anything about the current case? Last- I thought IG complaints were confidential? You can use the Army IG if you think the post IG is doing something wrong.

Unfortunately, back to the IG - with our without JAG support - is probably the only available route.

Depends on whether it's a legitimate beef or just a BS gripe about being singled out. Overall - tread lightly and think things through before taking further action(s). If the Chain of Command has broken down and is part of the problem, and IF it's legitimate and worth going to the mat for....the next course after consulting with those that would know, is contact constituent services of their Member of Congress. Last resort and only if nobody at Command can or will help. Best have ducks in a row though or it will not end well.

There must be more as I don't know how a Civilian Council will help deal with command level retaliation.

I'm not a Lawyer, that being said I have attended all the bloody training everyone goes through every year. IF a member files an IG complaint and the IG finds it to be unsubstantiated. Then a report is given to the member and the command about the complaint, along with any found deficiency's during the investigation. The IG does not dismiss things with out investigating unless the complaint is ... well bat shyte crazy. (i.e The command is discriminated against me because I want to wear a unicorn horn as part of my religion)... (Bronies don't ask!!). I have seen 2 times where the IG complaint was unsubstantiated and the member persisted with a "The CoC is out to get me" attitude. Never mind in both cases the Member had committed criminal and UCMJ violations. The CoC in both cases were forced to deal with multiple investigations and legal issues till they separated these walking Cluster ... I have also seen another 4 IG Complaints where it was substantiated and the Hammer came down swift and hard on some senior people.

One of those was filed on me because I required a TAD / limdu person to show up during work hours and sit at a desk instead of sleeping in and not showing up at all. They said I was "Religiously Discriminating against them and retaliating" They never could explain how I was doing these things as I didn't Rate them, write there Evals, or assignee jobs all I did was muster them Mon to Fri 0800 to 1600.

I guess my point in all of this is Trust the system, and don't dig your self into a hole. Unless you know for sure and have seen it be wary of believing another's perceptions.

I would suggest that they inspect their belongings and storage spaces on a very regular basis and prepare all of their own food, because you never know what they will find when they search your desk.
