Will i be treated like crap by NCO's at my duty station because I'm the new private?

Once you have shown the ability to do your job, and that you are trustworthy you should not have problems with the NCOs.

Once you are out of basic nothing is going to the same.

Dont be scared, they can smell fear! J/K, the "real" army is not like what it is in boot camp, it is a training enviornment to break you down then build you up. NCO's are people just like you, not monsters and most of them are good people that you can have real conversations with. Of course there are always those jerk offs but I wouldn't worry about it too much. Stand at parade rest when it is work related and show respect, but for the most part they are there to help you and guide you. As a PV1 when i first came into the army, my best friend ended up being an E5 at my new duty station. So, take a deep breath, and try not to stress.

If you're already in, you'd know the answer.
