It’s unclear what processes the Pentagon has in place to review the accuracy of its AI-generated reports to Congress. But such reports are a crucial element of congressional oversight intended to hold the US military accountable for how it uses taxpayer dollars—and so any AI-induced errors or mischaracterizations could undermine the accountability mechanism of such reports. This also comes at a time when the Pentagon has requested an unprecedented $1.5 trillion budget for the 2027 fiscal year.

Members of the US military have also been using generative AI tools to write personnel evaluation reports for non-commissioned officers and commissioned officers, generate commendation medal citations, and create counseling statements, according to a Small Wars Journal article.

The number of Department of Defense personnel using commercial AI tools such as Gemini through GenAI.mil has significantly increased from just 80,000 in December 2025 to 1.5 million in June 2026, the Pentagon CTO claimed during his remarks at the Hudson Institute. The Department of Defense has an overall workforce of approximately 3.5 million.

Google is among multiple US tech companies that signed agreements in 2025 with the US General Services Administration to make their AI tools available across federal government agencies for deeply discounted prices.

On May 1, the Department of Defense announced new agreements with “eight of the world’s leading frontier artificial intelligence companies” to deploy more AI tools on classified networks for “lawful operational use.” Those companies include SpaceX, OpenAI, Google, Nvidia, Reflection AI, Microsoft, Amazon Web Services, and Oracle.

The US government has not divulged how much it is paying the companies under the new contracts. But the list notably excludes Anthropic, which was blacklisted by the Trump administration after the tech company supposedly refused to allow its Claude AI models to be used in an unrestricted manner for autonomous warfare and mass surveillance.
