I want to know the answer to the following question:
What is one of the many ways the DCA utilizes passive defense to protect from enemy attacks?
All the background I'm provided with is that "It includes detection and warning; chemical, biological, radiological, and nuclear defense; camouflage, concealment, and deception; hardening; reconstitution; dispersion; redundancy; and mobility, counter-measures, and stealth.". Is that enough to answer the question?
