Mueller appears as an enemy reinforcement on turn 12 of Chapter 17A. He arrives only with his subordinates; Reinhardt was supposed to accompany him but Ishtar summoned him elsewhere on an emergency matter.[1]
Mueller has very little dialogue but has respect for his superior, Reinhardt, even reprimanding a soldier under his command for expressing frustration when Reinhardt is unable to assist directly due to retreating to see to Ishtar's distress. Even so, he is still willing to admit Reinhardt's absence is troublesome.[2]

Sigh... Mueler: Watch your tongue, soldier! Soldier: Y-Yes! I'm sorry! Mueler: But... Not having him here is indeed a problem..." — Mueller and a generic soldier in Chapter 17A, Fire Emblem: Thracia 776
