Befehlstaktik stands for "detailed order control".
It looks like Auftragstaktik is used in Israeli airports and TSA employ Befehlstaktik.
To quote an article about Auftragstaktik: "Ironically, since WW2, only the Israeli Defence Force seem to have come close to matching the Wehrmacht of WW2 in the exercise of command in this style".
So, they just use their military training and applied it to another field. And people from military works as screening officers at airports, for that being very good first job after military. Very clever.
