The Cassie Combat Assistant Artificial Intelligence was built to support her Marines in combat by giving them the information they needed to the survive on the coming battlefield. But she was also designed with another capability in mind. Fully mobile powered armor had been the thing of science fiction for decades, and countless people had grown up playing popular video game characters who wore them. But the engineering was difficult and it took all of those decades to make the idea work. By the time the first suits were ready for operational deployment, so was Cassie. She became not only the purveyor of information to her Marines, but the living mind of the armored suit her Marines wore.

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.
