Swearing-in to the IDF

I am supposed to swear in the IDF today (Training 02)
The wording of the oath is very discouraging to me. It says that every command must be done. And what if they give me a horrible course? To walk like a twat and suffer? And what if they tell me to stay up after I haven't eaten? And what if they don't give me a time to pray? And what if the command conflicts with the halacha? I really don't want to put myself in that corner. Does the solution of the declaration solve this? What can actually be done? thanks
