I know military vehicles are not built for comfort, but this looks unrealistic. It seems to me that the room available should be similar to an M113 or so.
Embarking and disembarking looks like it would be difficult the way it is now, and weapons and other gear are not even showing! If this was the true size it would pose a functional limitation on the vehicle I believe.
I heard there were some possible scaling issues with other vehicles, this convinced me to report this one too. It might be a mistake.
