10 U.S.C. § 2603
(a) Notwithstanding any other provision of law, a fellowship, scholarship, or grant may, under regulations to be prescribed by the President or his designee, be made by a corporation, fund, foundation, or educational institution that is organized and operated primarily for scientific, literary, or educational purposes to any member of the armed forces, and the benefits thereof may be accepted by him—
However, the benefits of such a fellowship, scholarship, or grant may be accepted by the member in addition to his pay and allowances only to the extent that those benefits would be conferred upon him if the education or training contemplated by that fellowship, scholarship, or grant were provided at the expense of the United States. In addition, if such a benefit, in cash or in kind, is for travel, subsistence, or other expenses, an appropriate reduction shall be made from any payment that is made for the same purpose to the member by the United States incident to his acceptance of the fellowship, scholarship, or grant.
