Final answer:
The statement is true; joint communication systems are crucial for command and control by the Joint Force Commander in conducting military operations, enabling efficient information flow, coordination, and decision-making.
Step-by-step explanation:
The statement that the joint communication system assists the JFC in C2 of military operations is TRUE. Joint communication systems are critical in ensuring command and control (C2), which are vital components in directing and managing military operations. These systems facilitate the flow of information among personnel, enhance coordination, and allow for the execution of orders and strategies efficiently.
The JFC (Joint Force Commander) relies on robust communication networks to exercise authority and direction over assigned and attached forces. In any military operation, the ability to communicate quickly and securely can be the difference between success and failure. Thus, the joint communication system is integral to maintaining situational awareness and decision-making in a timely manner.
