"The Pentagon has saved $5 billion through cuts to the departmentwide offices known as the “fourth estate,” Defense Department Secretary Mark Esper said during a keynote address at the Reagan National Defense Forum.

“In just four months of work we have saved over $5 billion. By decreasing overhead, divesting legacy activities and reducing lower-priority programs, we are able to invest more in the war-fighting requirements of the services. We can’t do this without the backing of Congress,” he said. “When our budget comes to the Hill next year, I ask you to support our proposals and enact the legislative changes needed to get these reforms across the finish line. And to be clear, this is just the beginning."

The so-called fourth estate includes 27 agencies, such as the Defense Intelligence Agency, the Defense Information Systems Agency and the Missile Defense Agency. A September 2018 report from the Government Accountability Office estimated those agencies collectively have an annual budget of at least $106 billion."
