Pics are looking great man. Just saw the movie Restrepo (look this one up). One thing I noticed is that after several months in the sandbox these guys were completely covered in afghan dirt/dust. I have yet to see from the BI team or addon makers a US soldier that really looks like hes been living in a nitty-gritty, treacherous desert for 12 months. I mean the pattern (digital, multicam) almost doesn't matter in the end because the weapons,clothing and skin on these guys are totally covered in dust. They look badass. You should take all your textures and overlay them with the light sand colors found in OA.
Just my two pennies worth...
