Pentagon 'Fortress America' plan for 90-day self-sustaining bases

The post describes a new U.S. basing resilience concept: major installations sustaining essential operations for ~90 days without external support, enabled by microreactors, microgrids that can island from the civilian grid, and large-scale battery storage. While not a frontline battlefield tactic, it is a notable operational/logistics innovation aimed at maintaining power, comms, water, and fuel under cyber/sabotage/drone-swarm disruption scenarios.
