It looks legit. Do this google search: http://www.google.com/search?as_q=service&num=100&hl=en&ie=UTF-8&oe=UTF-8&btnG=Google+Search&as_epq=&as_oq=&as_eq=&lr=lang_en&as_ft=i&as_filetype=&as_qdr=all&as_occt=any&as_dt=i&as_sitesearch=www.defendamerica.mil&safe=images for the word "service" on the defendamerica.mil web site. Read the titles and summaries of the page links returned. While possible, I don't think a scam site would create that much directly related content. Alan
