Stars and Stripes reports that "military troops, including those in conflict zones, may have their paychecks delayed if elected officials in Washington can’t work out a deal to fund government operations in the new fiscal year starting Oct. 1, the Pentagon said Monday."
"Large numbers of civilians could be temporarily furloughed, however, and it would require an act of Congress for them to get retroactive pay."
"In a memo sent late Monday, Deputy Secretary of Defense Ash Carter told DOD employees that the White House Office of Management and Budget had directed the Pentagon update its plans for a shutdown, as reported by Stars and Stripes last week."
