Never having bought a magnetic bolt I can't be sure of exactly how it works. As such if what I am about to present is already taken care of please feel free to delete this topic.
It is to my understanding that should one build a magnetic bolt it will stop the first attack that attempts to come through your portal. However, this is silly as it would totally be wasted on a 1 serviceman attack. Therefore I propose that one be able to set the value of which an attacking force has to be for the magnetic bolt to block the attack. For instance if one has 3000 servicemen, then perhaps only block attacks of greater than 3000 servicemen.
