Star Army Operations is the division of Yamatai that deals with the planning of military operations. It is commanded by the Chief of Star Army Operations.

“This galaxy is a hundred thousand light-years across, containing over three hundred billion stars. For all the expansion Yamatai has done so far, we have been effectively isolationist. We know too little of what lies outside of the Kikyo sector, even though our drives can take us there. Within known space, there are dozens of sapient species and governments. Imagine how many others are out there in those hundreds of billions of star systems. That is what the Star Army of Yamatai is up against. The unknown enemy.”

The role of Star Army operations is to:

1. Identify the Star Army's specific goals and objectives
2. Identify intelligence requirements for Star Army Intelligence
3. Plan force requirements
4. Administrate preparations for operations
5. Administrate execution of operations
6. Terminate operations as required by completion or circumstances
