Untersturmführer = “junior storm leader,” the SS equivalent of second lieutenant. Rip’s just been promoted to Obersturmführer for the posession of sugar. (Obviously the SS has gotten a bit lax.)
Rip: This is for you, Herr Major. I’m sorry it isn’t wrapped properly–
Major: Why, Untersturmführer, you got me two gifts!
Major: First the pfeffernüsse — it was delicious, by the way — and now these! I am promoting you to First Lieutenant.
Although you should have hidden the pfeffernüsse better.
Rip: But — but —
Schrö: Told you so.
