Several Bastion Fleets sit closest to the region from which Chaos forces repeatedly emerge. Their heavier strength follows threat and geography rather than a universal order of battle. A frontier facing near-perpetual war needs enough ready force to resist a breakthrough before it reaches deeper Imperial systems. The example shows how a nominally common fleet structure must still concentrate ships where risk is greatest.

Cadia, Agripinaa, Scarus, and Corona illustrate why fleets near a hostile frontier should be stronger than formations in quieter regions.
