U.S. troops will not get paid if lawmakers are unable to agree to a budget deal by Sept. 30, and some civilian Defense Department workers will be furloughed, according to the Pentagon’s No. 2.

“During a government shutdown, all military personnel would continue in a normal duty status; however, they would not be paid until Congress provides funding,” according to a memo sent Friday by Defense Defense Secretary Bob Work. “We have made necessary updates to our determinations of civilian employees who would continue to report to work in the event of a lapse in funding, and civilian employees who would be placed on furlough.”
