If you are really interested in becoming a ham radio operator, do it the right way. Find a local club in your area (they are everywhere) at arrl.org. Go to a meeting or two, and just start talking with other hams. Next, study for and take the technician class operator exam. There are 8 year olds with tech licenses, it's easy to get. It will allow you to operate on 6m, 2m, and a few other entry-level bands, and get you started. Some military radios for our vehicles are in the 6-meter bands, so if your only goal in this hobby is to operate a vehicular military radio, you're all set by this point!
Whether or not you continue in the hobby by getting higher-level licenses like the General or Extra Class, or by studying CW Morse Code, which is optional nowadays, is up to you. The higher a license you get, the more you gotta KNOW your electronics. But the higher a license you get, the more benefits you get too, like more bands to operate on, and more modes you can operate in (RTTY, SSTV, etc). It's a huge world, the ham radio hobby, all sorts of stuff you can do.
First step is go to a radio club meeting, and talk to them about all sorts of stuff. They'll be happy to help you on your way.
