I was married to a soldier for many years. They protect your right to get three square meals a day, to get your mail and to get something like four hours of sleep a day. They will make allowances for behaviors that would normally be termed "insubordination" if you have been awake excessively long (I can't recall the exact number of hours this applies to, possibly 24 hours). There isn't much else you can count on.

I am not saying that justifies torture. But your rights are substantially different in the military. You are officially AWOL if you are late to formation (i.e. Being late to work is a potentially serious crime if they want to make a big deal out of it). You cannot call in sick. You show up for formation and after formation you request sick call. If the doctor puts you on profile and bed rest, you might be excused from work for a few days.

Etc.

It is not a normal job.

Not exactly, something is only so if generally agreed by the public, and in this case the GP agrees that the Army can take any rights it wants.
