I think the Opfor are fine the way they are, I was reading somewhere but I can't remember this substance they used which could act as Kevlar, and stop any high speed projectile. Never mind it was called d30 gel, this could very well be in this neck brace that Opfor are using and could be quite comfortable. On the helmet it seems to be bulky just because one side has a camera feed and the other a light maybe? At the moment I compare Blufor and they seem to have the same but more advanced Kevlar vest and Opfor only with a non Kevlar/tactical vest, which in turn they might be using d30 gel in their clothing. This is all based on my observations and some knowledge on new technologies that might be further looked into by military's around the world. We do have to remember that their are many countries out there that develop and create new advancements in technology and a good saying is "Technology feeds on itself. Technology makes more technology possible-Alvin Toffler". WWII was a great example on how technology leaped some not believing their eyes what Germany had produced and yet to be built, but enough of me rambling on I leave you with this last quote"“The world as we have created it is a process of our thinking. It cannot be changed without changing our thinking― Albert Einsteinâ€.
