I forgot to say that I wanted to join the 82nd Airborne because it seems like it is the most similar to the 75th.
Not so, two completely different worlds. Any abn unit will give you an advantage in knowledge, however.
You will have to be lucky enough to branch infantry first - remember, for officers, needs of the service are priority one. Think of the officer world as a casino, you're always gambling something and there are no guarantees.
Do well in school, and even though I disagree with sending cadets to specalised schools, get as many slots as you can, airborne, dive, mtn warfare, air assault, etc. This will help.
Just keep in mind, regardless of what you branch, you will be an officer in one of the finest militaries in the world. Suck it up, and drive on.
