"It is your job to figure out what lies behind an order..."
Ah so that is why Japan lost the war.
I think it basically translates as “Shut up and obey the order. If you can’t figure out the reason for it, that’s your problem.”
Which is not exactly a great thing. She does not even have the information to understand the order. How is that going to teach her anything? They are students so shouldn't the "teacher" explain the orders so the students understand why the orders are issued?
