Mercedes Guard Line

Now I've seen quite a bit of information with regards to Mercedes Benz's Guard Lineup here. But I was wondering if the B6/B7 protection level will protect occupants in the vehicle from automatic weapons, sniper rifles as well as the shotguns?

Too bad they don't offer the Guard Lineup in Canada, Hong Kong or China; otherwise members of the elite in Canada and China could very well use an armoured vehicle for protection, due to increased crime.

i don't specifically know the levels of protection, but MB mentions that their top guard models protect from automatic rifle fire and grenades. Shotguns are relatively weak because of the spread shot, so they should clearly be covered, but on the contrary, sniper rifles can be extremely high powered, so i'm not too sure about the sniper rifle protection.
