Authorizes the Secretary of Defense to run a one-year pilot that gives monthly food coupons to junior enlisted service members to use at military commissaries. The pilot can operate at up to two installations chosen by the Secretary under specified criteria, prohibits coupon use for alcohol and tobacco, must supplement (not replace) existing food allowances or meal programs, and requires a report to congressional defense committees within 90 days after the pilot ends. Key terms (for example, "coupon" and "food") are defined in the text.
