On a lighter note. I wonder what his Secret Service code name is
In "In The Line of Fire" it's "Traveler."
I thought "Nelly" (the elephant packed her Trump) but that seems a bit whimsical for the SS.
"Storm Trooper" is a bit long on the radio. "Trooper" not quite senior enough.
"Siegfried" is maybe a bit Wagnerian (and I'm not sure how many have seen Django Unchained).
Perhaps they should just cut the subtlety and refer to him on radio as "The Leader."
