I am enlisted in the Army and I am looking at jobs that relate to computers when I reenlist because my ultimate goal is to program and fix computers and my question are these jobs still high demand because I don't hear much about those kinds of jobs anymore but I would still like to do it but just of curiosity are they?

Yeah they are actually even more in demand since things are becoming more and more electronic. Gift Cards for instance used to be all paper, but now almost all of them are on plastic like debit cards now. That is just one example of things growing more electronized. You wouldn't be out of it by going into a field like this.
