What is one of the primary functions of the Armed Forces?

One of the primary functions of the Armed Forces is to support and defend the U.S. Constitution against all enemies, both foreign and domestic. This duty is enshrined in the oath taken by military personnel, which emphasizes their commitment to the defense of the nation and its foundational legal framework. By focusing on this core responsibility, the Armed Forces ensure the protection of the nation’s sovereignty and maintain the principles upon which the United States was founded. This function encompasses not only direct military engagements but also the readiness to respond to threats and challenges that could undermine the security and stability of the country.

The other options, while important tasks, do not define the primary mission of the Armed Forces in the same foundational way. Enforcing laws domestically is primarily a function of law enforcement agencies rather than military forces. Conducting economic operations falls outside the traditional scope of military duties and is generally the realm of commerce and economic governance. Providing humanitarian aid, although often conducted by military units in disaster response situations, is considered a secondary function and does not represent the core mission of the military, which is to protect and defend the nation.
