College graduates are stepping out of university and into an uncertain labor market—but the U.K.’s chief of defence says the government’s defence department is ready to employ them with open arms.

While warning the nation of the escalating potential of conflict with Russia, Sir Richard Knighton stressed that the U.K.’s defence “cannot be outsourced to the armed forces,” and called on young citizens to step up.

He went as far as urging teenagers and graduates to ditch the corporate careers they may have been studying for, to join the military and help “meet the demands in the U.K. and of our allies to re-stock and re-arm.”

“Building this industrial capacity also means we need more people who leave schools and universities to join that industry,” Knighton said recently at a Royal United Services Institute event in Westminster.

The head of the military even asked parents to actively steer their children toward careers in defence.
