The National Guard plays a unique and essential role in the United States, carrying out missions that protect our communities, bolster national defense, and provide aid during emergencies. Yet, many people ask themselves, “What is the National Guard?” because they are unclear about what the National Guard is, how it operates, and what responsibilities its members fulfill.

If you’ve been wondering, “What is the National Guard?” you’re not alone. This guide will explain everything you need to know about this critical military organization and its significance for the country.

What Is the National Guard?

The National Guard is a specialized reserve component of the United States Armed Forces. It serves dual-state and federal missions, making it distinct from other branches of the military. While the National Guard Bureau states that the National Guard was established in 1636 at the Massachusetts Bay Colony, the Florida National Guard states its heritage dates back to 1565. No matter which National Guard (Florida or Massachusetts) a person recognizes as the first, overall, the National Guard is the oldest military organization in the country and remains a vital force today.

The Guard consists of two parts, the Army National Guard and the Air National Guard. In addition, some states like Texas, also have a third component, a state militia. In Texas, it is the Texas State Guard. These state militias normally do not participate in federal missions and usually these are purely state forces.

Each U.S. state, territory, and the District of Columbia maintains its own National Guard units, which fall under the authority of the state governor during peacetime. However, the federal government, specifically the president, can call the National Guard to active duty during national or international crises.

What is the National Guard Compared to Other Military Branches?

One of the most distinguishing traits of the National Guard is its dual mission. Unlike active-duty military branches (e.g., Army, Navy, Marine Corps, or Air Force), the National Guard is simultaneously responsible for state and federal duties.

State-Level Responsibilities

At the state level, the governor can deploy the National Guard to respond to natural disasters, civil disturbances, or other emergencies. For example:

During hurricanes, members of the National Guard assist with rescue efforts, distribute supplies, and restore order.
When wildfires spread, the Guard helps contain flames, evacuate residents, and safeguard affected areas.
The Guard also steps in during public health crises, such as setting up testing sites or distributing vaccines.

Federal Responsibilities

The president can activate the National Guard to support federal missions, which may include:

Serving alongside the active-duty military in overseas operations.
Reinforcing homeland security initiatives.
Providing logistical or protective support during major national events, such as inaugurations or disasters.
Members of the National Guard balance these duties alongside full-time civilian jobs, education, and family responsibilities, making them citizen-soldiers.

What is the National Guard’s Time Commitment?

The National Guard requires ongoing training to ensure readiness. Members typically participate in:

A weekend training session once a month which is ordinarily two days or one weekend.
Two weeks of annual training a year.
While this is the standard commitment, deployments—whether for state or federal missions—can require extended service.

What is the National Guard’s Emergency Response?

The National Guard frequently finds itself on the front lines of disaster relief and recovery. Their state-level role often places them among the first responders when communities face challenging situations.

Here are just a few examples of how the Guard has stepped up during emergencies:

Hurricane Katrina (2005)
When Hurricane Katrina devastated the Gulf Coast, the National Guard rescued thousands of individuals, delivered critical supplies, and provided medical care.
