When several companies from the Order of the Faithful pirate band attacked the Booker in 3066, they found the world defend by The Black Angus Boys. Unfortunately for the people of Booker, the wording of the contract with the Boys specifically charged them with defending government property, not the world as a whole.
Thus, Major Angus Black refused orders to engage the pirates so long as they were pillaging private businesses and residences. The raiders were quick to grasp this technicality and left Booker with their DropShip holds bulging with booty. Following the debacle, an infuriated Magistracy terminated the Boys’ contract.
