He scored his first aerial victory while with them, on 26 March 1916. By the next month, he was flying a Fokker Eindekker. On 28 June 1916, he transferred to KEK Avillers. He scored two more victories while with this unit, destroying an enemy observation balloon and downing an enemy airplane over Verdun. He then became an original member of Jagdstaffel 5; he joined the squadron on 21 August 1916 as a Vizefeldwebel.
Over a four-month period, from 26 August through 26 December 1916, Müller scored six more aerial victories to become his squadron's leading ace. While scoring his ninth and final victory on 26 December, he was so severely wounded in the abdomen that he was removed from combat duty.<
