I would recommend joining your High Schools ROTC (Reserve Officer Training Corps) unit. When I was in High School I was part of a NJROTC (Navy Junior Reserve Officer Training Corps) they taught me all about the military branches. It was nice because you are not only part of the team but also you get to live the life of a cadet. You wear a uniform and get inspected just as if you were reporting for duty. These units also have specialty teams which will allow you to try out different skills and see what you like. If you know the military is the way you want to go then becoming an officer within the ROTC class will be seamless for you.
If your school does not have an ROTC unit reach out to your local military recruiters and they can help find you a program to volunteer your time.
As for college, most fighter pilot programs is through the military branch you enlist in. Talk yo your local military recruiters to get information on local aviation training you can take. Remember they are there to not only help guide you, but also ensure the government helps pay for these kind of training's once you enlist.
Billy recommends the following next steps:
- Enroll in HS ROTC program
- Discuss Aviation Programs with Military Recruiter
