I am impressed. Jet and hover-bikes are extremely rare within the Imperium because of the amount of maintenance they require. The guard only rarely uses motorcycles, those combat Trikes are known among some formations, and I've deployed them with the Tanith once or twice in certain actions.

Why don't you ask Acumen for the hoverbike back, at least? The defense force could do with some mobile transport to react to situations more quickly.
