Key points

The American Civil Liberties Union and two other civil rights groups have sued the Defense Department in federal court, seeking records that explain why the Pentagon commissioned a study of women’s “effectiveness” in combat roles. The lawsuit asks a judge to enforce the groups’ request for documents showing the scope, purpose, methodology and anticipated use of the study, according to a report by Defense News published on October 19, 2026.

The ACLU filed the suit alongside two other organizations, the National Women’s Law Center and the Service Women’s Action Network. The groups argue that the Pentagon has not explained why it launched the review, and they want the government to disclose how the research will be conducted and what officials plan to do with the results.

Why the Study Comes a Decade After Combat Roles Opened

The study’s timing gives it weight beyond the immediate legal dispute. In 2015, under Defense Secretary Ash Carter, the Pentagon lifted its longstanding ban on women serving in ground combat jobs, opening roles in infantry and other front-line units that had previously been closed to them. The change ended a policy that had restricted women from many of the military’s most demanding assignments, and it was followed by years of debate about whether women could meet the physical and operational demands of those jobs without lowering standards.

Because that policy has been in place for roughly a decade, many military observers would expect any new review of women’s performance in combat to be grounded in data gathered since the change. The lawsuit’s central complaint is that the government has not said why it is revisiting the question now. Analysts who follow military personnel policy say that, when a department reopens a settled question, the purpose and design of the review tend to matter as much as its findings, because they shape how the results will be read and whether they lead to policy changes. That is an analytical point rather than a finding in the case.

Who Is Conducting the Study

According to the lawsuit, the Pentagon initially commissioned the Institute for Defense Analyses in January to study the topic over a six-month period. The Institute for Defense Analyses is a nonprofit research organization that works mainly on defense and national security questions for the federal government, and it is largely funded by federal money.

The lawsuit says the study was then moved in April 2026 to the Johns Hopkins University Applied Physics Laboratory, known as JHU/APL. The laboratory is a research center affiliated with Johns Hopkins University that conducts technical and analytical work for government clients, including the military. The lead researcher on the project, Jane Pinelis, is the author of a 2015 study prepared for the Marine Corps. That earlier report, according to the lawsuit, found “negative effects of mixed-gender units.”

The lawsuit states that the 2015 study “was widely criticized for its flawed design and biased analysis.” It says critics, including the Navy secretary of that time, argued that the work was aimed at showing that men are stronger than women, rather than at setting minimum standards and seeing who could meet them. That distinction is central to the debate. Supporters of a standards-based approach argue that the military should define the physical and performance requirements for each job and then test all applicants against them. Critics of the 2015 study argued that it framed the question around group comparisons, which they said could predetermine the answer.

The reassignment of the study has become one of the groups’ main points of concern. Under the lawsuit’s account, the change of institutions and the choice of lead researcher are the reasons the groups say the public needs a clear explanation of the project’s purpose.

Hegseth’s Public Statements on Women in Combat

The lawsuit places the study in the context of Defense Secretary Pete Hegseth’s past comments. Citing reporting by The War Horse, the complaint says Hegseth relied heavily on the 2015 Marine Corps study to support his argument that women should not serve in combat roles, as laid out in his book, “The War on Warriors.”

In that book, he wrote: “Dads push us to take risks. Moms put the training wheels on our bikes. We need moms. But not in the military, especially in combat units.”

In a November 2024 interview on the Sean Ryan Podcast, Hegseth stated his view directly: “I’m straight up just saying we should not have women in combat roles.” The source material notes that Hegseth has since softened his rhetoric on the issue. Critics, however, say he continues to pursue the same agenda, presenting it in terms of military standards.

The ACLU’s statement, issued through Gillian Thomas, senior counsel for the organization’s Women’s Rights Project, makes the same connection. Thomas argued that Hegseth has “repeatedly, without evidence, questioned women’s ability to serve in ground combat,” and that he aims to deliver research that validates what she described as his “biased” views. She added: “Now, without explanation, he has commissioned a study of women’s performance and assigned it to a researcher with a record of criticizing women’s combat readiness. The public has a right to know why, and what he plans to do with the results.”

These statements are the views of the plaintiffs and their critics. The source material does not include a direct rebuttal from the Pentagon in the reporting provided, so the department’s explanation for the study is not part of this account.

What the Lawsuit Asks For and the Legal Question Ahead

The lawsuit asks the court to compel the Defense Department to release records showing the scope, purpose, methodology and anticipated use of the study. Those four categories are designed to answer different questions. Scope covers what the study will examine. Purpose explains why it was commissioned. Methodology describes how the research will be conducted, including what data and criteria will be used. Anticipated use covers what the department intends to do with the findings, such as whether they would inform policy, training or standards.

The reporting does not specify the legal statute the groups are relying on. Requests for federal government records are commonly handled under the Freedom of Information Act, but the source material does not say whether that law is the basis of this case, and this article does not assume it.

If the court agrees to hear the case on the merits, it would weigh whether the government must release the requested information. Courts in records disputes often examine whether an agency has responded adequately to a request, and whether any exemptions it claims are justified. The outcome would depend on the court’s reading of the request and the government’s response, which are not described in the source material.

Why the Dispute Matters

The dispute touches on several issues that affect service members and the public. For service members, the rules for assignments in combat units shape career paths, promotion opportunities and the question of who serves in the units that carry the highest physical and operational risk. For the public, the outcome of a study like this could influence how the military recruits, trains and assigns personnel, and how it explains those decisions.

The question of standards is at the heart of the debate. Military leaders have long said that combat units require specific physical and performance capabilities. Advocates for women’s service say those requirements should be defined by the job itself and tested in a way that treats every applicant equally. Opponents of women in combat roles have argued that differences in average physical capacity mean the military would face challenges in mixed-gender units. The lawsuit’s position is that the government should be open about its goals before any conclusions are drawn, because the design of a study can determine the answer it produces.

For the groups filing the lawsuit, transparency is the core issue. Their argument, as stated by Thomas, is that the public has a right to know why the study was launched and what will follow from it. That argument does not depend on whether the study’s eventual findings are favorable or unfavorable to women’s service.

What to Watch Next

Several developments will determine how this story moves forward. The first is the government’s response in court. The source material does not describe any answer or filing from the Defense Department, so it remains unclear whether the department will release records, contest the request or seek to narrow it.

The second is the study itself. The lawsuit notes that the project was moved from the Institute for Defense Analyses to JHU/APL in April 2026, and that the original plan called for a six-month timeline starting in January. Whether the study proceeds on the same timeline, and whether its methodology is made public, are open questions.

The third is the political context. Hegseth’s past statements, including those in his book and on the podcast, are likely to remain central to how the study is interpreted. Analysts expect that any results published from the review would be read against those earlier comments, and that the debate over the purpose of the study will continue regardless of the court’s ruling on the records request.

For readers, the key point is that the lawsuit does not yet decide whether women should serve in any combat role. It asks the government to explain why it is studying the question and how it plans to use the answer. The outcome will show whether the public can see the goals and methods of a government study on a policy that has been in place for a decade.
