She has been working on ship engines since she was only four years old. Probably due to spending her entire life on haphazard Generational ships, she is very nonchalant when it comes to ship maintenance. She deactivates "oversensitive" radiation detector warnings, and puts out sporadic fires with her hand. She is very determined and can quickly repair and run the ship's engines, even after they burn out.
When the Attero device was activated by the Vanir, Katana brought Lt. Colonel John Sheppard and Dr. Radek Zelenka to the planet holding it. On their way, Radek worked together with Mila to speed up the hyperdrive of Katana's ship, despite feeling uncomfortable with her. Mila was eventually able to get the ship quickly to M6H-987, although the hyperdrive burnt out in the process. Nevertheless, she and Zelenka got it operable again after several minutes.

Mila as a character could be a tribute to Jewel Staite's character on "Firefly" series - Kaylee Frye.
