Military Slot Machines: The Hidden Gambling Problem on US Overseas Bases

Slot machines run by the US Army on overseas military bases earned about $91 million in the 2024 fiscal year, up from $87 million a year earlier, even as gambling disorders climb among service members. A September 2025 report from the US Government Accountability Office (GAO) found the Department of Defense lacks clear guidance on who is responsible for preventing and treating gambling problems in the ranks, and recommended the Pentagon fix that by September 2026. Congress banned slot machines on domestic US bases in 1951, yet the machines remain legal and lucrative on installations in Germany, Japan and South Korea.

The issue returned to the spotlight this week through the story of Dave Yeager, a US Army veteran who developed a slots addiction while serving overseas and now works as a behavioral health specialist helping others. His account, combined with the GAO's findings and a fresh push in Congress to remove the machines, has reopened a long-running debate: should the US military profit from the same gambling products it bans at home?

What is the military slot machine problem in 2026?

The core issue is that the US military both operates gambling machines and treats the service members who become addicted to them. The Army Recreation Machine Program (ARMP) ran 1,889 slot machines across 79 overseas locations as of summer 2025, generating tens of millions of dollars a year that funds morale, welfare and recreation (MWR) activities. At the same time, the number of service members formally diagnosed with a gambling disorder has risen steadily, and the GAO says the Pentagon's support system has not kept pace.

That tension sits at the heart of the 2026 debate. The revenue is real and helps pay for base amenities, but so are the harms, and critics argue the arrangement puts the institution in a conflict of interest that no civilian casino operator faces with its own customers.

What are the key facts?

• ARMP slot machines earned $91 million in FY 2024 and $87 million in FY 2023, according to the GAO.
• 1,889 slot machines operated across 79 overseas military locations as of summer 2025.
• Service members diagnosed with a gambling disorder rose to 185 in FY 2024, up from 169 in FY 2023 and 136 in FY 2019, per the GAO.
• Congress banned slot machines on domestic US bases in 1951, but overseas installations are exempt.

How much money do the machines make?

The Army's overseas slot machines are a significant revenue stream, earning $91 million in fiscal year 2024 according to the GAO. That was up from $87 million the year before, and independent reporting has put peak annual revenue above $100 million. The proceeds flow into MWR budgets that fund recreation, entertainment and family programs on base.

Because the money is ring-fenced for troop welfare, defenders argue the machines pay for services that would otherwise need separate funding. Critics counter that the model effectively taxes the very personnel most at risk, since junior enlisted troops far from home are among the heaviest users.

How many service members have gambling problems?

Formal gambling disorder diagnoses among service members have risen every year the GAO measured, reaching 185 in fiscal year 2024. That figure was 169 in FY 2023 and 136 in FY 2019, a clear upward trend that officials link partly to the explosion of online and app-based sports betting rather than slot machines alone.

Survey data suggests the diagnosed cases understate the picture. In the Army's 2024 Periodic Health Assessment, 4.8 percent of participants, 15,039 out of 310,482, reported gambling in the previous 12 months, and 402 of them reported restlessness or anxiety when trying to cut back, an early marker of disordered play.

What did the 2025 GAO report find?

The GAO concluded that the Department of Defense does not have clear guidance defining who is responsible for gambling prevention and treatment, leaving gaps in care. Its report, GAO-25-107700, found inconsistent responsible gaming practices across the overseas programs and recommended three fixes: clarify accountability, designate and train staff to assess and treat gambling disorder, and standardise responsible gaming across recreational gaming programs.

"Unhealthy gambling behaviors are an increasing problem across the Armed Forces today due to the ease of online and app sports betting." Army Lt. Col. Isaac Lopez, Clinical Psychologist, Defense Health Agency Public Health.

The Department of Defense agreed with the GAO's recommendations and set a target of September 2026 to implement them. You can read the full report on the GAO website.

Why are slot machines banned at home but not overseas?

Congress prohibited slot machines on domestic US military bases in 1951, but the ban never extended to installations on foreign soil. The result is a legal split under which the same machine that is illegal on a base in Texas is a sanctioned revenue source on a base in Germany or South Korea.

The historical logic was that overseas gambling would keep troops on base and channel spending into welfare funds rather than local economies. Decades later, critics say that rationale has not aged well as understanding of gambling addiction has grown and as the overseas programs have become a durable funding pillar the military is reluctant to give up.

Why are service members more at risk?

Military life combines several recognised risk factors for gambling harm: youth, distance from family, exposure to trauma, and easy on-base access to gambling with limited state-level responsible gambling rules. Research and clinicians have long noted that service members can be more vulnerable to disordered gambling than the general public, and stigma around help-seeking makes the problem harder to catch early.

Concerns about career impact and security clearances can deter troops from reporting a gambling problem, meaning cases often surface only after significant financial or personal damage. That dynamic mirrors wider challenges in the sports betting boom, where fast, always-on wagering has outpaced the support systems built for an earlier era.

Who is Dave Yeager and why does his story matter?

Dave Yeager is a US Army veteran who developed a slot machine addiction while stationed overseas and now works as a behavioral health specialist, helping other service members and veterans confront gambling harm. His firsthand account gives a human face to the GAO's statistics and has helped push the issue into policy conversations.

Yeager has argued for pragmatic harm reduction where an outright ban is not on the table. "If it's gonna be dangerous, at least keep them on the reservation, if you will," he said, reflecting the view that if the machines stay, the military must own the duty of care that comes with them.

Is Congress moving to remove the machines?

There is a renewed legislative push to strip slot machines from overseas bases, led in part by Congressman Paul Tonko, who has proposed banning the machines outright. The effort faces resistance because the revenue underwrites MWR programs, but the combination of the GAO findings and rising diagnoses has strengthened the case for reform.

Separately, fiscal year 2026 marks the first time federal funding has been allocated specifically for gambling addiction research within the military, a milestone advocates hope will build the evidence base for tighter safeguards or removal. Recommendations from the relevant Defense medical research program are expected in 2027.

How does this compare year on year?

The trend lines run in the same direction: revenue up, diagnoses up. The table below sets out the core figures from the GAO.

Metric	FY 2019	FY 2023	FY 2024
Service members diagnosed with gambling disorder	136	169	185
ARMP slot machine revenue	Not stated	$87 million	$91 million

What does this mean for the wider industry?

The military case is a sharp example of a challenge the whole gambling sector faces: operators being asked to protect the same customers they profit from. As commercial operators build advisory committees and player safety teams, the Pentagon is being pressed to hold itself to a comparable standard on responsible gaming, or to exit the business entirely.

For the responsible gambling debate, the story reframes the operator as the state itself, which raises the bar on accountability. It also underscores how the growth of online sports betting, cited by military clinicians as a driver, is reshaping harm patterns well beyond traditional casino floors and shifting attention toward the industry's overall problem gambling rate.

What happens next?

The Department of Defense has until September 2026 to act on the GAO's recommendations, which will be the near-term test of whether guidance and treatment actually improve. In parallel, the congressional push to remove the machines and the first tranche of federal research funding will shape the longer debate over whether the overseas program survives in its current form.

Either way, the direction is toward more scrutiny, not less. The machines have operated quietly for decades, but a documented rise in harm and a critical federal audit have made the status quo harder to defend.
