What is the purpose of the observation scope?

[jscharpf]

Sorry if this sounds like a silly question, but I don't see the point of the observation scope. It seems like it has the same size and magnification as the attack scope.

Do I lose anything by using just the attack scope for everything? What was the observation scope used for in real life? Why even have two if they're the same?

Is there something wrong with my installation? Should they be different?

Sorry for my ignorance, just seems like you could save some money and just have one scope lol

I'm using GWX with whatever was in the list (can't remember all items on the list but most of what came with it, I installed).
