For quite some time I wondered how strong graphene is as armour.  Don’t get me wrong, I understand what graphenes is and would no doubt make excellent armour.  

I want to know how good it would be and what design of armour is the best with this wonder material.

Would a spaced design work better or just having multiple stacks of graphene layered onto each other? Let’s assume armour for a soil set in the field.  Not concealed and armoured jackets for now.
