Your resume is what you make it. It can be as detailed or as plain as you want it to be. I spent 20 years in the service, and when it came time to retire, I had never even really applied for a job in my life to that point. So I started off with a resume, then after every job interview I asked for a one-line review of my resume. Most employers are more than happy to explain what they liked and didn't. Eventually I got so good that the phone was ringing off the hook, finally that one job, the PERFECT job came along, and here I am. So don't give up, you have to start somewhere.
