would this be Onager sized, or closer to Super MAC sized? as for the Contact Harvest mass driver strike, the attack only worked, as ONI PSI sort of noticed, only because it was a surprise attack, "Once the mass driver fired, the ONI PSI assumed the aliens would identify its power source and launch a retaliatory strike." Building an SMAC sized weapon wouldn't be fiscally sane considering that you would only have 2-3 shots before a covenant ship bullseyed you.
