Southern Arizona resident here. Rural southern Arizona doesn't mean that you are not in a district with half of Tucson because of how the districts are broken up. If you are south east Arizona you are in a district that has a fair portion of Tucson (read DM Air Force Base) and Sierra Vista (Ft. Huachuca Army) so the military is well known and highly competitive in those districts. If you are southwest Arizona, you include some of Yuma which has heavy Marine influence. Even though you are rural, military has a huge presence in those two districts and they are competitive. Are they as competitive as Colorado Springs is for Air Force or Annapolis area for USNA? No. There is influence though so you won't be the only one walking into the office. To give you an idea (and I am dating myself with this info) when I went through the process in 2010 for the class of 2015, the senators interviewed 50 people each. My representative at the time interviewed I think 50-75 for all academies. Not everyone got an interview. Some people got more than 1 nomination though. I ended up with 2 for AF and 1 for Navy. The senators at the time tried not to duplicate nominations for kids to the same academy to spread out state nominations. All this to say, best of luck! You will have competition, but they do their best to recognize talent and spread out nominations to maximize the number of kids presented to the academies from the state.
