I just remembered... in one of my research book (Can't remember where, frantically looking), it talked about the NVA/VC (likely the nva =) ) using a quad barrel ZSU 12.7mm AA gun. (ZSU -7? My mind is blanking...) I'm pretty sure they didn't have many (if any) 20mm shilkas, but .50cal/12.7mm aa was pretty common. Anyone know what it looks like, and if it looked similar to the shilka? If so, it would be relatively simple to replace the cannon with a quad 50 cal...
A quick question which I should know already know but don't: What did the VC use in the way of vehicles? I know the NVA had armor, but did the VC use jeeps/cars/trucks regularly? Anything heavier? far as I know they were mostly on foot, but...
