Why is it "Bullship?" All of the troops are there because they said
that
they would obey all lawful orders from those appointed over them.

Precisely.

One can laud people for carrying out their orders in the face of
danger, without agreeing with the orders given. The troops don't have
the luxury of questioning their mission, but the society and freedoms
the armed forces were intended to protect grants the rest of us the
ability to question our leaders and debate the wisdom of their
decisions.
