What is meant by passive air and missile defense?

Passive air and missile defense refers to measures and strategies aimed at minimizing the impact of enemy attacks or facilitating recovery from such attacks, rather than directly engaging or intercepting them. This approach typically includes actions such as fortifying infrastructure, improving camouflage, employing tactics to conceal assets, and implementing redundancy in systems to protect against potential damage.

Utilizing passive defensive measures is crucial for maintaining operational capability and ensuring the safety of personnel and critical equipment. Strategies involved in passive defense often focus on resilience and damage limitation, preparing to absorb impacts, and quickly restoring functionality after an attack. This would not involve actively seeking out or engaging with an enemy, which distinguishes passive defense from other forms of military operations that may prioritize direct confrontations or offensive maneuvers.
