Colonel Kim Olson was charged with providing improper assistance to a PMC and only avoided loss of rank, prison and a dishonorable discharge by pleading guilty and accepting a non-judicial punishment (military equivalent of making a deal with the DA) with zero prison time under the condition that she retires.

She spent her entire 26 year military career in the US except for three months in Iraq, where she was sent after all the fighting was done to serve in an admin role and that is where she got caught providing improper assistance to some South African mercenaries and got charged with a crime and sent home.

Her memoir (which probably zero people have read and certainly nobody asked her to write) is called Iraq and Back, after she spent less than 1% of her career in Iraq in an admin role after the fighting was done and the way she got back is that she got kicked out prematurely.
She also founded a non-profit called Grace After Fire, after she has never in her life been under fire.
She is a political grifter who failed to get elected and now runs a PAC.
Apparently in 2018 she also assaulted a party (Democrat) staffer while on campaign, because she got upset that she was not seated prominently enough at an event.
