This is John Sopko. As the Special Inspector General for Afghanistan Reconstruction (SIGAR), he's spent the last three years tracking how the U.S. is spending billions in rebuilding Afghanistan.

While wholly depressing, his quarterly reports have been an invaluable open-source resource for people who track the development of Afghanistan's security forces. Or at least they were.

In his latest report, issued Thursday, something changed. "This quarter, Resolute Support Mission, the new NATO-led mission to train, advise and assist the Afghan National Security Forces, classified 31 of its responses to SIGAR's data call," the report said. In other words, NATO answered the questions Sopko asked, but then told him that the public can't know what they said.
In an epic bit of shade, Sopko's office decided to list all the questions that they asked that are now apparently too sensitive for the public. Here's a few of them, along with the response we can only assume NATO would now provide if you asked.
