I wanted to try out another genre and decided to do a military/special ops story or something of that nature. SO I was wondering if anyone knew of a site where there's rules or tips on military dialogue because I'm pretty much clueless. Or if you have tips of your own, that would help too.

I wrote a script called Balance that had some military dialogue in it. And although I got a few key things wrong in regards to age and rank, I got most of dialogue by searching the net looking for military terms, military speak and added that in. It didnt hurt that I have a friend who is a Vietnam vet as well.

Also, you could contact your local recruiting office and just explain your situation. They might be willing to help and steer you in the right direction. Good luck.

Steve is right. We live in a time where information is just a click away.

A quick search gives me these right off the bat:

http://www.military.com/join-armed-forces/military-terms-and-jargon.html
http://www.npr.org/blogs/parallels/2013/12/04/248816232/u-s-military-lingo-the-almost-definitive-guide
http://en.wiktionary.org/wiki/Appendix:Glossary_of_military_slang
http://www.vetfriends.com/lingo/

And these are just the first few on the first page. The days of relying solely on the humble Encyclopedia are gone. :)

Of course if you know someone i.e., the 'horse's mouth' or even know someone who knows someone, that'd be even better in terms of authenticity.

Steve brings up a really good point - get someone with military experience to read your work. Although the culture of the Armed Forces is more or less the same, there are tons of differences that separate each branch.

Just remember the situation your characters are in. A lot of films go over-the-top in regards to mixing military lingo in everyday speech. The devil is in the details, but someone with a military background will iron those out with ease.

Good luck!

^^^ That.  You probably needn't go any further than your family.  Everyone has a family member, be it an uncle, cousin, parent, whatever, who's been in the military.  Hell, just about every male in my extended family has been in the military at some point, including myself (Army, infantry, '90-'93).
