Realistic? Maybe darker, but I was getting the impression it's still very much an exaggerated version of reality like Rainbow Six.

Like even in real life the stuff SWAT members put on their arms wouldn't stop a bullet. Maybe cushion against baseball bat. there's just not enough arm there to cover it without having a heavy ass arm and effecting shooting, because shooting first is a much more reliable way of not getting shot than having some material in the way
