Should my resume include Community Involvement

I am currently in the process of changing careers from US Navy to the IT industry. I have rewritten my resume at least 45 times. Each version is slightly to extremely different from the other based on outside input. I thought I was finally finished rewriting it when someone told me that I should include community invovlement as well. HELP!!! Is this something that employers really want to know at the initial stage or something for reserved for the interview process???
