I would like to enlist in the military but Im unsure of what job to choose?

Im interested in joining the air force or army, but i want a job that's challenging and rewarding. I don't want one where ill be sitting down all day, but rather something more active, I thought about mp since i like leadership or ariel gunner because it sounds challenging. I originally wanted combat medic or mp but i heard both of those mos's in the army get shitty jobs on base and aren't treated well. FYI im a female so im kinda limited but my asvab scores are very high. Btw, are soldiers respected/treated better in the air force? My friends in the army hate it but they have no plans of leaving so im kinda confused??
