Civilians also contributed to the war effort with the purchase of U.S. Government Defense Savings Bonds or "War Bonds." These were purchased at a discounted price and redeemed for full value at maturity. As the U.S. military recruited young men for service, civilians were called upon to do their part by buying War bonds, donating to charity, or, if they worked in industry, going that extra mile for the troops.
