Technology
Everyone is using it
AI. The kill chain, compressed from days to seconds.
Organization
Nobody has built it
The staff, task-organized around the problem. Its architecture unchanged since Napoleon.
Doctrine
It comes last
Written from what the new organization proves in the field, through iteration.
The tank existed for more than twenty years before Blitzkrieg. Then the Germans built a new kind of organization: fast tanks and aircraft, linked by radio, all fighting in concert. The Panzer division. After many iterations, Blitzkrieg became its doctrine.
AI is the 21st-century tank. It has yet to spawn organizational or tactical change. Yet it holds the potential to radically change the one thing that has not changed since Napoleon: the architecture of the military staff.
Staffs tailored to each problem, task-organized and augmented by ODAI with whatever expertise the task demands, will find new ways of using force. Through iteration, those ways become the new doctrine.
ODAI will be the foundation for whatever the Blitzkrieg of the 21st century becomes.
