Anselm was a Human engineer of the male persuasion, serving within the ranks of the Alliance Fleet.
Despite lacking prior military service or any formal combat instruction, Anselm enlisted with the Alliance Fleet following the devastation of his homeworld by the Galactic Empire in the time leading up to the Battle of Yavin. His technical skills allowed him to advance to the grade of Lieutenant. During that pivotal battle, he functioned as the technician responsible for Luke Skywalker's X-wing. He frequently declined to carry a firearm, even when faced with perilous situations, unless specifically instructed to do so. Subsequently, he continued his service within the New Republic Defense Force. He led the technical team (comprising Tomrus, Shen, and Kline) that accompanied Han Solo and Luke Skywalker on their mission to the Katana fleet.
