Is your major included in the rated positions when you commission?

Basically what the title says. If I’m not accepted into USAFA, I plan to major in aerospace engineering at an accredited program where the course is quite difficult. I read some where like 10-15% have a 3.5+ GPA (not to say it’s not achievable). I know GPA plays a prominent role in your score, so I was wondering if your major and it’s subsequent difficulties are accounted for when you are vying for the job you want in the Air Force. I just think it’s unequitable to compare equally an English major to an engineering one.
