The Pentagon office tapped in 2022 to oversee the military’s responsible use of artificial intelligence had filled just three of its 10 authorized positions for the mission as of February 2026, even as the department pursues a strategy to accelerate AI development, a government watchdog found. The Government Accountability Office discovered that 29 of 64 efforts outlined in the Defense Department’s Responsible AI Strategy and Implementation Pathway remained incomplete as of April 2026.

According to a report published Oct. 14, the GAO also found that staffing shortages had hindered the Chief Digital and Artificial Intelligence Officer’s ability to take additional steps to implement responsible AI, which the department uses to help accelerate AI adoption. GAO recommended that the department address staffing needs in its Responsible AI Division, which falls under the Chief Digital and Artificial Intelligence Office, and issue a formal charter for the working council.

“Responsible AI should be considered the same as operationally effective AI,” said Owen Daniels, associate director of analysis at Georgetown University’s Center for Security and Emerging Technology.

Effective testing, evaluation, verification and validation practices can help the military manage risks while ensuring systems operate as intended and operators understand their strengths and limitations, Daniels said. The GAO found that the Responsible AI Working Council did not meet from late 2024 until August 2025.

Chief Digital and Artificial Intelligence Officer, or CDAO, officials told the watchdog agency that other priorities, including developing guidance for generative AI and contributing to government-wide AI risk-management resources, had prevented the Responsible AI Division from organizing meetings.

Rep. Don Bacon, R-Neb., raised a related concern about accountability during a May 2025 hearing regarding the Pentagon’s AI posture. “It’s my observation that the Defense Department doesn’t lack in the number of principals, but rather, it often struggles with too little clarity in who is responsible for what.”

Officials from four DoD components told the GAO they faced implementation challenges during the hiatus that could have benefited from greater collaboration. Six of the 10 DoD components surveyed said sharing responsible AI resources and best practices would increase their ability to incorporate the department’s six Responsible AI tenets into their AI use cases.

The council resumed meetings in August 2025, but the GAO found it still lacked a formal charter defining its responsibilities and specifying how frequently it should meet. “Without a charter that defines roles and responsibilities for the council ... and that specifies the frequency of council meetings, the council is at risk of lapsing again,” the GAO report reads. “Such a lapse could increase the risk of DOD facing Responsible AI implementation issues that it would not have the collaborative capacity to swiftly and effectively resolve.”

CDAO officials told the GAO they were unlikely to fill vacant positions or increase staffing while the office underwent restructuring, following its realignment to the Office of the Under Secretary of Defense for Research and Engineering.

In response, the GAO argued that “by ... taking action to ensure it has staff in place to meet those needs,” CDAO could make better progress toward its goal of accelerating AI across the department.

Daniels said the staffing shortfall could make it more difficult to build AI literacy throughout the force. “Operationally, the force needs to become AI literate, as warfighters will be responsible for determining when to deploy AI-enabled systems,” he said. Service members need to understand AI systems’ limitations and recognize when delegating decisions to machines may be inappropriate, rather than defaulting to a machine’s judgment, Daniels said.

“Exercising meaningful human control — or to use the department’s term, appropriate levels of human judgment — over a military AI system requires robustly understanding a system’s operating boundaries through development, rigorous testing and evaluation, and training,” he said.

The DoD agreed with the GAO’s two recommendations to issue a charter for the Responsible AI Working Council and address the Responsible AI Division’s workforce needs, according to the watchdog.

The GAO also urged Congress to order the department to implement earlier recommendations, including defining the responsibilities of organizations involved in AI activities and assigning responsibility and a timeline for identifying and managing the department’s AI workforce.

In a Sept. 21 letter, Sens. Jack Reed, D-R.I., Mark Warner, D-Va., and Chris Coons, D-Del., expressed concern that the Pentagon’s AI push could be outpacing its governance efforts.

“Recent events have given us growing concern about the extent to which agencies under your oversight have prioritized acceleration of AI capability adoption and ‘experimentation’ over effective governance,” the letter reads. Reed has also called for Congress to establish clearer guardrails for military AI.

“Congress must do its job and provide balanced oversight, standards, and rules of the road,” he said.
