Mirrors Save Lives?

Just wondering how many of you DCS players have had your virtual lives saved from something you noticed in your mirrors. (And, how many of you who fly without them wish you had them in some mission)

I know it's not many, since LOMAC 1 I've probably seen bullets or missiles coming at me from astern that I ducked because I saw them...

Couple of times, but I like them to look at myself...
