Which of the following is a military role in homeland defense?

• A. Protect defense critical infrastructure
• B. Defend the homeland to include sovereign airspace, territory, and territorial seas
• C. Develop international coalitions for defense
• D. Deter potential adversaries through diplomacy and sanctions

Answer: (B)

Defending the homeland means safeguarding the country’s sovereignty by protecting its airspace, territory, and territorial seas. That’s the military’s direct duty in homeland defense: using forces to deter, detect, and respond to threats that enter or threaten to enter national borders and waters. Keeping sovereign airspace under control—air defense and air operations—alongside securing land and maritime boundaries, are classic, explicit military responsibilities tied to defending the nation from external aggression. While protecting critical infrastructure, building international coalitions, and using diplomacy and sanctions are important to national security, they align more with civil-m military cooperation or diplomatic tools rather than the core military task of guarding the homeland’s physical boundaries.
