The Cassie Combat Assistant Artificial Intelligence came into her own when Marine tanks, mechs, or other heavy weapons of war became available to her. She could help individual Marines fight better by giving them the information they needed. But tanks and mechs she could control on her own. She would take the orders of her Marines and fulfill them at the speed of electronic thought that only another AI could match. And she was born from the combined minds of two of the best AIs ever born. Her heavy combat units became the most dangerous combat formations on Earth and beyond, and soon dominated the future of warfare in the stars.
