You won't be infantry, if you choose another job. I was in the army for 4 years, I was a cook and never was infantry, yes I trained with the infantry, but I never did there job. If you want some of the best education in the military, look more towards the Navy. They get the best of the best, even better than the Air Force. If I could do it all over again I would have gone Navy. btw there is no Infantry in the navy, the navy's infantry are the marines.
