'The military doesn't suck, it's a branch of the government given the task to safeguard the freedom of the citizens of the country. They only obey (legal) orders. If you think their actions suck it's the politicians you should bitch at, not the ones that, risking their lives, obey their orders.
They're just following orders.

Yes, that's how hierarchical structures work.
And you know very well that in all western militaries you are not only allowed, but have a duty to refuse to obey an order that's illegal.
