What Is the National Guard
The National Guard is a part-time military force that belongs to each state and to the nation at the same time. On most days a governor commands it for floods, fires and emergencies at home. The president can also call it into federal service, and then it answers to the Pentagon like any other soldier.
Key facts
- Congress authorized 434,300 Guard members for 2026: 328,000 Army and 106,300 Air (CRS).
- Who commands the Guard, the governor or the president, decides whether troops may do police work.
- Courts stopped all three federalized city deployments of 2025. The ones under a governor kept going.
- The 2025 city deployments cost $496 million through December, by CBO’s count (CBO).
The Guard’s two bosses are written into the Constitution. Congress may call forth the militia to “execute the Laws of the Union, suppress Insurrections and repel Invasions,” while the states appoint the officers and train them (Article I, Section 8). That split is why the same soldier can be a state responder on Monday and a federal one on Friday.
Who Commands the Guard in Each Duty Status
The label on a Guard member’s orders decides who is in charge, who pays, and whether the troops may act as police. It is the first thing to look for when troops arrive.
The three ways the National Guard serves at home

The District of Columbia is the exception to the table. It has no governor, so its Guard always answers to the president, and the Justice Department holds that it can serve outside the Posse Comitatus Act. Our Posse Comitatus Act explainer covers that dispute and each rung of the law in detail.
Title 32 is the status the 2025-26 deployments leaned on after the courts ruled. The statute lets a Guard member be ordered to support “operations or missions undertaken by the member’s unit at the request of the President or Secretary of Defense” (32 U.S.C. 502(f)). A governor who agrees can send troops on a federal mission and keep police powers the Posse Comitatus Act would otherwise bar. A governor who refuses can say no.
When a President Can Federalize the Guard
A president has two main laws for taking command of a state’s Guard, and the Supreme Court narrowed the one used in 2025. The first is the Guard call-up law, 10 U.S.C. 12406. It allows federal service in three cases:
- The country is invaded or in danger of invasion.
- There is “a rebellion or danger of a rebellion against the authority of the Government of the United States.”
- The president is “unable with the regular forces to execute the laws of the United States.”
The law adds that orders “shall be issued through the governors of the States” (10 U.S.C. 12406). The fight in court turned on the third condition.
In Trump v. Illinois on December 23, 2025, the Supreme Court denied the government’s request to let the Chicago deployment proceed. The Court concluded that “regular forces” in the call-up law “likely refers to the regular forces of the United States military,” not civilian law enforcement. A president who cannot lawfully use the military to enforce the law first needs an exception to the Posse Comitatus Act, so the call-up law alone likely could not support the deployment. The vote was 6-3, with Justice Kavanaugh concurring in the judgment and Justices Alito, Thomas and Gorsuch dissenting. Because the ruling came on a stay application, it is not a final decision on the merits.
The second law is the Insurrection Act. It is the main exception to the Posse Comitatus Act, and it lets federalized troops enforce the law directly. It has not been invoked since 1992. Our Insurrection Act explainer walks through what it allows and why the Illinois ruling points toward it.
Every National Guard Deployment Since 2025
All three federalized deployments ended in court, and the three that stayed under a governor or the D.C. Guard kept going. That split tracks the table above: the Posse Comitatus Act limits troops under the president, and it does not reach the others.
Where each city deployment stands
As of October 5, 2026
- Los Angeles (federalized under Title 10) Ended, violation found
A judge found on September 2, 2025 that the deployment willfully broke the Posse Comitatus Act. A December 10, 2025 injunction ordered the remaining troops returned to the governor, and the Ninth Circuit let it take full effect on December 31, 2025. Troops: 4,000 Guard members and about 700 Marines. (source)
- Portland (federalized under Title 10) Ended, permanently blocked
A judge permanently blocked the federalization on November 7, 2025. The troops were demobilized January 6, 2026. (source)
- Chicago (federalized under Title 10) Ended, blocked, 6-3
The Supreme Court kept the deployment blocked on December 23, 2025 in Trump v. Illinois. The troops were withdrawn in January 2026. (source)
- Washington, D.C. (D.C. Guard plus Title 32 troops) In litigation, continuing
Found likely unlawful November 20, 2025, then stayed on appeal December 17, 2025. The Pentagon extended it through Inauguration Day 2029. Troops: nearly 5,000 from more than 20 states (July 2026). (source)
- Memphis (Title 32, under the governor) In litigation, continuing
A state judge blocked it November 17, 2025. An appeals court reversed on standing April 28, 2026, so it can continue. (source)
- New Orleans (Title 32, under the governor) Agency action, status after August unclear
Extended in March through August 31, 2026. No court challenge and no later extension found. Troops: up to 350 Louisiana Guard members; about 120 by spring 2026. (source)

The money adds up fast. The Congressional Budget Office put the 2025 city deployments at $496 million through December, about $93 million a month at their end-of-year size, and $18 million to $21 million a month for every 1,000 Guard members sent to a city in 2026 (CBO letter to Sen. Merkley, January 28, 2026).
Does a Guard Deployment Cut Crime?
The best study so far found that the Washington deployment cut petty property crime and had no measurable effect on violent crime. The Niskanen Center, a nonpartisan think tank, counted a 24% drop in opportunistic property crime in the first six months. The troops stood mostly in high-visibility public spaces, “exactly the locations where opportunistic property crime tends to occur,” the authors wrote (Military Times).
The White House rejects that reading. Spokeswoman Abigail Jackson called the study an “out-of-touch” analysis and said the deployment had turned Washington “into a safe and beautiful haven for residents and visitors alike.”
A second analysis looked at more cities. The Center for American Progress, a progressive think tank, ran time-series tests on violent crime, homicide and gun violence in each deployment city and found that “only one city in one model produced a statistically significant result,” Memphis (CAP, July 13, 2026). Both studies are early, and crime in Washington was already falling before the troops arrived.
The National Guard at Home, 1957 to 2026
The Guard’s domestic history runs in both directions. Presidents invoked the Insurrection Act in 1957, 1962 and 1965 to enforce civil rights rulings against state resistance. A governor’s troops fired on Kent State students in 1970. A president sent federal troops to Los Angeles in 1992 at the governor’s request, and in 2025 federalized California’s Guard over the governor’s objection, before the Supreme Court stepped in.
- Arkansas Guard federalized at Little Rock Eisenhower takes command of the Guard the governor used to block nine Black students.
- Federal troops sent to Ole Miss Kennedy invokes the Insurrection Act to end the riot over James Meredith enrolling.
- Alabama Guard federalized for Selma Johnson sends Guard troops to protect the march to Montgomery.
- Ohio Guard fires at Kent State Troops under the governor kill four students and wound nine.
- Federal troops sent to Los Angeles The last time a president invoked the Insurrection Act, at the governor's request.
- California Guard federalized over the governor 4,000 Guard members and about 700 Marines sent to Los Angeles.
- Supreme Court reads the call-up law narrowly Trump v. Illinois keeps the Chicago deployment blocked, 6-3, on a stay application.
- D.C. deployment extended to 2029 Nearly 5,000 troops from more than 20 states patrol Washington.
When the Guard was used at home: 1957: Arkansas Guard federalized at Little Rock (Eisenhower takes command of the Guard the governor used to block nine Black students.). 1962: Federal troops sent to Ole Miss (Kennedy invokes the Insurrection Act to end the riot over James Meredith enrolling.). 1965: Alabama Guard federalized for Selma (Johnson sends Guard troops to protect the march to Montgomery.). 1970: Ohio Guard fires at Kent State (Troops under the governor kill four students and wound nine.). 1992: Federal troops sent to Los Angeles (The last time a president invoked the Insurrection Act, at the governor's request.). June 2025: California Guard federalized over the governor (4,000 Guard members and about 700 Marines sent to Los Angeles.). Dec 2025: Supreme Court reads the call-up law narrowly (Trump v. Illinois keeps the Chicago deployment blocked, 6-3, on a stay application.). July 2026: D.C. deployment extended to 2029 (Nearly 5,000 troops from more than 20 states patrol Washington.).
1957: Arkansas Governor Orval Faubus used the state Guard to keep nine Black students out of Central High School. President Eisenhower invoked the Insurrection Act, federalized the Arkansas Guard and ordered it to stand down, and sent the Army’s 101st Airborne Division to protect the students (Brennan Center guide; Eisenhower Library).
1962: After a mob besieged James Meredith and federal agents when he enrolled at the University of Mississippi, President Kennedy invoked the Insurrection Act and sent several thousand federal troops to end the riot (Brennan Center guide).
1965: President Johnson invoked the Insurrection Act and federalized the Alabama Guard to protect the march from Selma to Montgomery (Brennan Center guide).
1970: On May 4, 1970, Ohio Guard troops called to Kent State by the governor fired into a crowd of demonstrators. Four students died and nine were wounded (Kent State University).
1992: At the governor’s request, President George H.W. Bush invoked the Insurrection Act and sent federal troops to Los Angeles, though state-controlled Guard troops had mostly quelled the unrest before they arrived (Brennan Center guide). It is the last recorded invocation of the Insurrection Act.
June 2025: Defense Secretary Pete Hegseth federalized 2,000 California Guard members on June 7 and 2,000 more on June 9, and about 700 Marines followed (Newsom v. Trump). Governor Gavin Newsom sued.
December 2025: The Supreme Court ruled 6-3 in Trump v. Illinois, on a stay application, that the call-up law likely could not support the Chicago deployment.
July 2026: The Pentagon extended the Washington deployment through Inauguration Day 2029, as troop numbers doubled to nearly 5,000 from more than 20 states (NPR).
If You or Someone You Love Serves
Guard members are citizen soldiers with civilian jobs, and a domestic mission raises practical questions the recruiting sites do not answer. This is general information, not legal advice.
If you or a family member gets orders
Pick the situation closest to yours.
I got orders and need to know who I answer to
- Read the authority line on your orders. It will say state active duty, Title 32, or Title 10.
- State active duty and Title 32 mean the governor commands you. Title 10 means the president does.
- Ask your unit what the mission allows you to do, especially any contact with the public.
Federalized troops fall under the Posse Comitatus Act unless the Insurrection Act is invoked; troops under a governor do not (CRS).
I am worried about my civilian job while I am deployed
- Give your employer notice of your orders as early as you can.
- Keep copies of your orders and your release date.
- If your employer refuses to take you back, file a complaint with the Labor Department's veterans employment office.
USERRA protects the jobs of Guard members on full-time National Guard duty and on state active duty of 14 days or more, or for a declared national emergency or major disaster (38 U.S.C. 4303). Shorter state duty depends on your state's law.
I have questions about an order I was given
- Ask your chain of command to explain the legal authority for the mission.
- Talk to a military lawyer at your unit's legal office. The advice is free.
- Write down what you were told and when.
Courts found parts of the 2025 deployments unlawful, and the rules differ by duty status. A lawyer can tell you what applies to your orders.
What a Guard Deployment Does Not Settle
- A court win against a federalized deployment does not reach troops under a governor. The Posse Comitatus Act does not apply to the Guard when it is not in federal service, which is why the Title 32 and D.C. missions continued (CRS).
- The Supreme Court’s Illinois ruling is not the last word. It came on a stay application, used the word “likely,” and did not address how much deference a president’s findings get.
- The crime studies are early. Both cover months, not years, and Washington’s crime was already falling before the troops arrived (NPR).
- A Title 32 mission needs a willing governor. The federal government can request and pay for one, but the governor decides whether to accept (32 U.S.C. 502(f)).
Frequently Asked Questions
What does the National Guard do?
It has a state mission and a federal one. Under a governor it responds to emergencies such as disasters and civil disorders. When it is ordered into federal service, control passes to the president, and it can be called to active duty in war or a national emergency like other reserve forces.
What is the difference between the National Guard and the Army?
The Army’s regular force is a full-time federal force with the president as Commander in Chief. The Army National Guard belongs to a state and answers to its governor until it is ordered into federal service. Most Guard members are part-time, generally training one weekend a month and two weeks a year.
Can the president send the National Guard to my city?
Yes, in limited ways. A president can ask a willing governor to send the Guard under Title 32, command the D.C. Guard directly, or federalize a state’s Guard under the call-up law or the Insurrection Act. After Trump v. Illinois, the call-up law alone likely cannot put federalized troops on police duty.
Can a governor refuse to send the Guard?
A governor can refuse a Title 32 request, since it depends on the governor’s consent. A governor cannot block a lawful federalization, but can sue, as California, Oregon and Illinois did in 2025.
What You Can Do
-
Ask your governor where they stand. A governor decides whether to accept a federally requested Title 32 mission and whether to send troops to another state. More than 20 states sent Guard members to Washington in 2026.
-
Check the authority when troops arrive. Look for the legal basis in the announcement or the court filings, then use the table above to see who commands them and what they may do.
-
Ask your House member to back the National Guard Proper Use Act. H.R. 5604 would bar troops and Guard members from being ordered to enforce immigration law.
-
Know the neighboring laws. Read the Posse Comitatus Act explainer, the Insurrection Act explainer and the martial law explainer, so no one can tell you troops have powers they do not.
-
Write your senators and representative with the letter below. It asks them to cosponsor the Insurrection Act of 2025, which would end any deployment under that law after seven days unless Congress approves it.
