Masir Trach was a human male who served as a commander and scanner officer in the First Order, and held a rank befitting that of a senior officer. Previously assigned to the Resurgent-class Star Destroyer Finalizer, when Trach was transferred to the Steadfast he was caught in the power struggle between Generals Armitage Hux and Enric Pryde, the commanders of the Finalizer and Steadfast respectively. Although Trach could sense the tension between the two Generals and was aware that the orders they gave him carried ulterior political moments, to avoid dispute he chose to focus on carrying out the letter of his orders.
