where to report a scammer pretending to be a US soldier?

Hey all!
I'm pleased to have found this site as after joining a penpal site, I have been flooded by scam emails and I have been frustrated by not being able to do anything about it. The flood of emails has now slowed down but I'll post whatever I get!
I have one (and have had more previously) that claims to be from a US soldier in Iraq who wants my help in the safekeeping of two military trunk boxes, wants my partnership in business, help to secure funds, blah, blah, blah!
It doesn't seen to fit into the categories you have, so where should I post it?
Many thanks

That would be one of your common or garden variety 419 scams. You can put it here.
