I don't think there are and I'm assuming you mean the clothes they wear during the war. But if anyone(modders) is interested in them, there are some decent looking models (I guess) from the game 7554 (an unpopular Vietnamese-made game).
Here's the topic I posted about the game months ago:http://www.gunetwork.org/t2727-7554-glorious-memories-relived?highlight=7554
Or you can access the homepage directly through this link: http://www.7554.vn/
It's a buy2play game ($10 on GamersGate - http://www.gamersgate.com/DD-7554/7554 ), or you can get its demo instead which is free for download (you might have difficulties trying to find the demo because most of the results shown are from Vietnamese pages, I could assist you with that).
