Key Takeaways
• Nearly 10,000 active-duty troops support border enforcement with DHS seeking 20,000 more National Guard.

The question of whether the U.S. military can enforce immigration law has become a major topic in 2025, especially as the government takes new steps to address border security and immigration enforcement. This issue involves old laws, new executive orders, and changing roles for both military and law enforcement agencies. As of June 26, 2025, the situation at the United States 🇺🇸 southern border is shaped by legal limits, presidential actions, and practical needs on the ground.
Who Is Involved and What Is Happening?
President Trump’s administration has taken strong action to involve the U.S. military in supporting immigration enforcement. In January 2025, President Trump signed an executive order called Protecting the American People Against Invasion. This order told the military to help “repel the invasion and seal the United States 🇺🇸 southern border from unlawful entry.” The U.S. Northern Command, which is a part of the military, was given the job of stopping large groups of people from crossing the border without permission. The Department of Homeland Security (DHS) was also told to build and run detention centers for people caught crossing the border.
As of mid-June 2025, nearly 10,000 active-duty U.S. military troops are stationed at the southern border. DHS has asked for 20,000 more National Guard troops to help with deportations and other enforcement work. In addition, about 700 military personnel have been sent to Florida, Louisiana, and Texas to support immigration enforcement, joining almost 5,000 National Guard members and Marines already working in Los Angeles. These troops are under federal control, which means they follow orders from Washington, D.C., and are paid by the federal government.
Why Is the Military Involved?
The main reason for involving the U.S. military is to help manage the large number of people trying to cross the border and to support immigration enforcement agencies like U.S. Customs and Border Protection (CBP) and Immigration and Customs Enforcement (ICE). The Trump administration has also canceled several immigration policies from President Biden’s time in office and told DHS and the Justice Department to speed up the removal and prosecution of people who break immigration laws.
The executive order also encourages state and local police to work with federal immigration agencies. This is done through something called Section 287(g) agreements, which allow local police to act as immigration agents. This move has made it possible for more law enforcement officers to help with immigration enforcement, but it has also raised concerns about civil rights and the impact on local communities.
How Does the Law Limit the Military’s Role?
The Posse Comitatus Act
The Posse Comitatus Act is a federal law passed in 1878. It says that the U.S. Army and Air Force cannot be used for domestic law enforcement unless Congress or the Constitution gives special permission. The Navy and Marine Corps are also restricted by Department of Defense rules. The main goal of this law is to protect civil liberties and prevent the military from having too much power over everyday life in the United States 🇺🇸.
The Insurrection Act
The Insurrection Act is an important exception to the Posse Comitatus Act. It allows the President to use active-duty military and National Guard troops inside the United States 🇺🇸 in certain situations, such as when there is a rebellion, insurrection, or when regular law enforcement cannot keep order. President Trump has used this law to justify sending military troops to the border.
What Can the Military Actually Do?
Even with these new orders, the military is not making arrests or detaining people directly. Instead, military personnel are helping with tasks like:
- Processing undocumented immigrants at detention centers
- Providing transportation and logistics support
- Setting up and maintaining equipment and facilities
- Freeing up law enforcement officers so they can focus on arrests and removals
This means the military is mostly working behind the scenes, making it possible for immigration officers to do their jobs more efficiently.
How Are CBP and ICE Involved?
The Trump administration has also increased the role of CBP agents in enforcing immigration laws inside the United States 🇺🇸, not just at the border. About 500 CBP agents, including Border Patrol, Office of Field Operations, and Air and Marine Operations, have been sent to help ICE with arrests across the country. ICE has been told to triple its daily arrest numbers to 3,000 people per day. Right now, ICE is detaining about 49,000 people, which is more than the 47,000 beds Congress has paid for. Of those detained, 43% have no criminal record.
What Does This Mean for Immigrants and Communities?
Supportive, Not Direct, Military Involvement
The military’s role is mainly to support, not to enforce. They help with processing and logistics, but they do not arrest or detain people themselves. This is important because it keeps the military within the limits set by the Posse Comitatus Act.
More Aggressive Enforcement
With more troops and more law enforcement officers working together, the government is able to detain and deport more people. The use of 287(g) agreements means that local police can act as immigration agents, which has led to more arrests and removals.
Concerns About Civil Rights
Some people worry that using the military and local police in this way could lead to violations of civil rights. There are concerns about racial profiling, loss of trust between communities and law enforcement, and the risk of the military having too much influence over civilian life.
Impact on Families and Communities
The increased enforcement has led to more families being separated and more people being held in detention centers. There is also more fear in immigrant communities, as people worry about being arrested or deported even if they have not committed any crimes.
Legal and Expert Opinions
Legal experts say that while the President can use the Insurrection Act to deploy the military, the Posse Comitatus Act still limits what the military can do. The current approach, where the military provides support but does not make arrests, is designed to stay within these legal limits.
Civil rights groups warn that using the military in immigration enforcement can create fear and mistrust in communities. They argue that it can lead to mistakes, abuses, and violations of people’s rights.
Supporters of the policy say that the military’s help is needed to handle the large number of people crossing the border and to keep the country safe. They believe that the military’s logistical support allows law enforcement agencies to do their jobs better and faster.
As reported by VisaVerge.com, the debate over the military’s role in immigration enforcement is likely to continue, with strong arguments on both sides about the best way to secure the border and protect civil liberties.
Historical Background
The use of the military in immigration enforcement is not new, but it has always been controversial. In 1996, Congress added Section 287(g) to the Immigration and Nationality Act, allowing local police to help ICE with immigration enforcement. This was a big change, as it meant that more people could be involved in enforcing immigration laws.
Past presidents have also sent National Guard troops to the border, but usually in support roles. What is different now is the scale and intensity of the military’s involvement. The Trump administration has sent more troops and given them a bigger role than ever before.
What Could Happen Next?
DHS’s request for 20,000 more National Guard troops suggests that military support for immigration enforcement could grow even more. The administration’s push to triple ICE arrests and expand detention centers shows that aggressive enforcement is likely to continue.
At the same time, legal challenges and political debates are expected. Some lawmakers and advocacy groups are already questioning whether these actions go too far and whether they respect the limits set by the Posse Comitatus Act and the Constitution.
