@ArmyROTCApplicant - keep in mind that any tour is going to give you just a small glimpse of what life is really like as a cadet. It's going to be a challenge, but it that is what you are looking for it is the right place.
Do yourself a favor if you decide to go and truly give it your all. It's going to be tough and there will be many times you are going to fill like quitting or wish you never started in the first place. There will be a few cadets who try to skate by and maybe get an "injury" when the going gets tough. Definitely report a real injury if it happens, but don't be the person who is trying to take the easy way out or not giving your best. Cadre will see that and even if you are not the leader of the pack they will see who is really busting their butt trying and who is trying to skate by.
Best of luck to you.
