Not really upset with the realistic optics as far as zoom level and field of view. I do have an issue with the optics on the US vehicles. They go from moderately white-cloudy (m476) to the virtually unusable almost fully clouded optics like the (m375). If this is what the WWII tankers had to deal with, I am glad I was a grunt and the view over my M16 sight was at least clear. Those guys had a lot to contend with. You have to admit trying to find a semi-hidden M4 with the cloudy sights is a challenge, they are almost invisible. Don't even ask me what I think of trying to de-ack with these sights, ack positions may as well have Harry Potters cloak over it. So, I jokingly ask for a function key that will simulate a spritz of windex on the sights.
