I WAS thinking about joining the air force. But now im not so sure since they seem to have to many people as it is. What I was looking for is a job that I could do that involves using Navigation, GPS units, radar or something of that nature. Im not sure what would be the best branch for me. I'm not in the best of shape yet, i did weigh 336 pounds and manged to get myself down to 170. My best mile 1/2 was 13 something. I am working hard on running and working on pushups and sit ups and whatnot. Another thing is, id like to use this job as a carrer... possibly retire for the military with it if I could. any help/guidence would be appreicated. I do NOT have any college credits or anything, just a HS diploma.
