how did ONE ship blowing up manage to destroy a halo installation almost the size of earth?
also, if a nova bomb was requested to destroy the high charity (although it is much smaller than a halo) (while pillar of autmn managed to blow up the first halo by itself) and ONE nova bomb destroyed 3/5 of the elite's fleet at Joyous Exultation, why couldn't the UNSC just detonated their own ships, since they can do so much damage?
