resume writing program??

I believe most resumes are written in MS Word, and most versions of Word include some canned templates in various formats.  Coming out of the military you may want to consider more of a functional format which focuses on your skills and abilities rather than a more traditional chronological format that might not resonate with a civilian HR person.  Resumes are usually sent electronically rather than hard copy--Word or PDF files are fine.

On that note, unless you're applying for a military-oriented job or are pretty sure your resume will be screened by former military folks, one of your most important tasks in writing your resume will be to translate your skills and experience into civilian language.

Good luck!

P.S.--I'm a retired SWO and frequently involved in interviewing candidates for my company--let me know if you'd like some pre-screening advice.

Aside from the advice already offered, I recommend that you ultimately save your resue to pdf format. Send the pdf file, not the MS Word version. With pdf, you preserve all your formatting and the document looks pristine. With different versions of MS Word out there, your formatting might suffer a little on the receiving end.
