This site, Weapons and Equipment, has lots of info on what tools the modern Marine recon force is equipped with these days. The site is part of the United States Marine Corps Force Recon Association website. I hope that they don't mind me using one of their photos to call attention to this terrific group of extraordinary Marines.
The article may have even more info than some of you might want, but I like it.
Update: As long as you are reading about Force Recon, here's Part I and here's Part 2 of the article.
Update 2: added proper credits and link to Force Recon Association
