All you need is to add flags to:
-BTR-80
-MT-LB
-BMP-2
-M113
-Land Rover Defender
-M35 Truck
-T-72
-UH-1
-Mi-24
-Mi-17
-Humvee
-Gopher
As for the soldiers, the BF2 USMC will do fine (they are very similar to our modernized soldier kits) with re-textures to fit the camo.
Weapons are pretty much existing in PR (AK-74, M4, G3, SVD, M249, M2, MG3, PKM).
Hmm, maybe I'll commit myself to it in the summer after I've finished this semester.
