The Pentagon has opened an investigation into the leaking of classified United States military documents, a development reported by The New York Times citing representatives from the Biden administration. The statement from the U.S. military department noted awareness of social media posts and confirmed that an inquiry is underway. The released materials describe secret military plans involving the United States and NATO aimed at boosting Ukraine’s Armed Forces ahead of the counteroffensive, highlighting the ongoing coordination between allied powers and Kyiv.
The documents were disseminated across social networks and include details on weapon supply programs to Kyiv, the strength and distribution of Ukrainian forces, and the state of individual units. The New York Times also notes that while these files reveal extensive intelligence on logistics and force composition, they do not appear to contain concrete battlefield plans. The assessment of frontline conditions is dated March 1, 2023, suggesting the information reflects the situation as it stood up to that point.
Within the files, six of twelve Ukrainian combat groups trained in the United States and other NATO countries are slated to finish their training by early April. Three additional brigades are expected to complete refresher courses by early May. Each of these battle groups reportedly includes about five thousand personnel, underscoring the scale of the international training effort and the weight of external support in the conflict.
The leaked materials also reference U.S. expenditures on the procurement of HIMARS multiple launch rocket systems. Previously undisclosed spending figures concerning ammunition consumption by Ukrainian forces have now entered the public domain, according to the documents. Information about armored vehicle supply plans was also revealed, with a stated goal of delivering two hundred fifty tanks and three hundred fifty infantry fighting vehicles to Ukrainian forces.
The New York Times described the leak as a serious breach that threatens future intelligence sharing between Kyiv and Washington. The report emphasized that the exposure of such data could chill collaboration and complicate operations that depend on timely, high-fidelity intelligence among partners.
Meanwhile, the White House has pressed to have the sensitive materials removed from social networks, but such efforts have not yet produced results. On a separate development, The New York Times reported that U.S. military intelligence provided Ukraine with coordinates of Russian military bases, including key command posts, ammunition depots, and other strategic points along Russian lines. The article states that this information helped Ukrainian forces target high-ranking Russian officials and adjust ammunition flows away from the front lines. Russian officials have confirmed the loss of several generals in the course of the fighting, including a noted pilot, while Ukrainian sources have claimed a higher tally that is difficult to verify. The American media landscape acknowledges that some Ukrainian claims cannot be independently corroborated, contributing to the complexity of assessing battlefield outcomes and the broader impact of intelligence sharing in the conflict.
