Which of the following is NOT one of the four advantages of joint warfare?

• A. Instills teamwork
• B. Allows greater optimization of forces
• C. Prepares the military for future operations
• D. Increases interservice rivalry

Answer: (D)

Joint warfare is about unity of effort across military services, working together as a coordinated team rather than in separate, isolated branches. That approach brings several clear advantages. Instilling teamwork across branches helps different units learn how to operate smoothly with each other, improving communication and trust during operations. Allowing greater optimization of forces comes from coordinating capabilities, logistics, and tactics so power from air, land, and sea can be applied where it has the most impact. And preparing the military for future operations builds interoperability and readiness, so forces can adapt to evolving threats with standardized procedures and shared doctrine.

Increasing interservice rivalry, on the other hand, would undermine coordination, hinder information sharing, and reduce the effectiveness of joint planning. That’s why it isn’t considered an advantage.
