Dominique Kohl is shown as a Sergeant First Class in the Military Police of the U.S. Army. From 1990 to 1997, Kohl worked under Major Jack Reacher and quickly proved that she was a smart, determined, and very skilled officer. Reacher mentions she is "young but smart, capable, determined," and "a natural," which gives an idea about her talent and potential.

Kohl is in her late 20s, athletic, and has a sure-of-herself attitude. Since she is very responsible and good at investigating, she is resourceful to Reacher's team. As she is very thorough and careful in her work as a military police officer, Kohl is excellent at detecting issues with systems and people who are lying.

Reacher season 3's investigation into Xavier Quinn was mostly about how he sold secret military information to enemy countries without permission. It was up to Jack Reacher and Sergeant First Class Dominique Kohl to find out what Quinn was doing, which included spying, blackmailing, and selling weapons.

As part of their investigation, Kohl questioned Roland Gorowski, a military agent who turned to spying because Quinn took his young daughter. Kohl and Private Anthony Frasconi were trying to arrest Quinn when he killed Frasconi and captured Kohl. He then tortured her to get information from her before killing her. Her death makes Reacher want to get justice for Quinn.

Kohl's commitment to her job is clear as she takes on the task of arresting Quinn. Even while being severely tortured, she refuses to reveal information, which leads to her death.

In the beginning, Reacher season 3, episode 4, shows Jack Reacher and Dominique Kohl having a conversation that depicts Kohl's excellence in investigation. Reacher is impressed by Kohl's quick analysis as they talk about the case over coffee.

When Reacher asks her to figure out what kind of crime it was, she answers right away that coercion was the main factor. She gives a good reason for her point of view and adds that the suspect, Korowski, doesn't seem like the typical criminal. Reacher respects her ability to think critically, which is why he made her an official member of the team and saw her as a natural investigator.
