I don't know the game, but I wondered if you are you going for a desert-board or more like a city-board (Kabul-fights etc) ?
Next Sunday I'm visiting a military show (http://www.wingsandwheels.be) where some of my friends are in a reenactment-group doing the Airborne-group... There are many more reenactment-groups and a convention, but most are of course about WWII (since we were a little involved in that..).
But there are always other groups which go for other wars, such as Vietnam and Afghanistan.
Those reenactment-groups usually handle historically and logistically as right as possible.
If I encounter an Afghanistan-reenactment group, I'll try to find some answers where to look for info, or if there's anything worth to photograph, I'll do so.
If there's anything more specific you need to know, let me know and I'll see if I can find answers there... (or if you want something from other wars for other games or so
(well, no SF or Fantasy I bet...
I could of course try to reenact a fantasy war and dress myself as an orc there.. but I bet I would look like a total fool then...)
