The Goldwater-Nichols Act had which primary effect?

• A. Streamlined theater command and enhanced jointness
• B. Increased service autonomy and reduced joint operations
• C. Created no new commands
• D. Weakened Special Operations Command

Answer: (A)

The main idea behind the Goldwater-Nichols Act was to make the U.S. military operate more as a single, integrated force rather than a collection of separate services. It did this by reshaping the command structure around unified combatant commands for theaters and by strengthening the authority and emphasis on joint operations across all services. This shift toward jointness meant planning and executing operations through joint channels, with service chiefs becoming more subordinate to unified command ambitions and the Chairman of the Joint Chiefs of Staff gaining a stronger role in coordinating effort across services. It also introduced joint duty requirements for promotion to ensure officers are prepared to operate in a joint environment, and it established USSOCOM as a unified command to coordinate special operations more effectively.

That combination—creating unified theater commands and elevating joint purposes across promotions and planning—best captures the primary effect. The other options describe scenarios that the act did not produce, such as increasing service autonomy, creating no new commands, or weakening Special Operations Command.
