you realize you joined the military right? you wont find classified interesting crap on a particular subject you want.
You mentioned AVN, well grab a coffee sit in front of a computer, read on the types of aircrafts you may like to work on and start from there. For example You like the globalmasters, start there and read what you can on wiki. Theres SO MUCH to learn, you'll find yourself busy for quite some time, who know's you'll look like a genius when you get posted to 429
Some say there is no stupid question... now re-read your question you ask yourself, and figure it out, you're going to be an AVN tech one day, think outside of the box!
