The Chairman of the Joint Chiefs of Staff Standing Defense Support of Civil Authorities (DSCA) Execute Order (EXORD) would not enable sufficiently rapid sourcing to provide for the reception, staging, onward movement, and integration of forces for a domestic complex catastrophe.
In a domestic complex catastrophe, with effects that would qualitatively and quantitatively exceed those experienced to date, the demand for Defense support of civil authorities would be unprecedented. Meeting this demand would be especially challenging if a cyber attack or other disruption of the electrical power grid creates cascading failures of critical infrastructure, threatening lives and greatly complicating DoD response operations.
