I assumed you meant aviation? If you want to go into aviation why not join the Air Force. There's more opportunity's there to get near aircraft (not necessarily MX since theyre scaling those numbers back). With any service, you get what you take out of it. Walk in with a piss poor attitude not ready for the change in environment and you're bound to be one of those guys thats shits all over their military service. Know as an enlisted troop early in their career theres alot of being told what to do...learn to play the game. Play it...get other shit done while youre in the service (school, training, etc.). The end-goal, atleast for me, is to build my resume and develop as many tools possible that will be viable outside the service. Its been an honor for me to serve the few short years I have, and the next few years ahead of me. After 7-8 years I think I may punch out, move back closer to family, friends, and my GF. Thats after getting the chance to fly in jets, earn 2 graduate degrees and have the GI bill in my back pocket. Some of the smartest folks Ive ever met were in the service (USAF and Army). I loved alot about it...I also HATED alot about it. Time away from friends and family. Not being able to do certain things you want. Its give and take...just know exactly what you want to take from your service.
