I also got my electronics training in the military but it's not for everyone. After I got out I went on to school and got an AA degree in Electronics and a BS in Management. I probably could have done as well had I skipped the stint in the military and went straight to school.
As pointed out, computer techs don't make that good of a living but you can use your technical background to leapfrog into other areas. I spent my early career as a tech but then switched to software and just retired after working 30 years as a programmer/software engineer.
