Integrated defense efforts aim to achieve __________ desired effects.

The correct answer is based on the widely recognized goal within integrated defense strategies, which is to achieve nine desired effects. Integrated defense emphasizes a comprehensive and coordinated approach to protection and response across various domains, including land, air, sea, space, and cyber environments. Each of these domains interacts to create a robust defensive posture that enhances overall security and resilience.

The emphasis on nine desired effects underscores the complexity and multifaceted nature of modern threats, requiring a well-rounded strategy that incorporates multiple capabilities and perspectives. It reflects the understanding that achieving optimal security outcomes necessitates a broad yet cohesive framework. This involves not just physical deterrents but also technological advancements, intelligence gathering, and inter-agency cooperation.

The other numbers of desired effects do not align with established frameworks used in integrated defense discussions and practices, which are tailored specifically to a nuanced approach involving the recognition of diverse threats and the need for versatility in response.
