Section 55
SEC. 55. An enlisted man dropped by reason of removal, or by reason of having been beyond the jurisdiction of his organization, may be taken up at any time within three years after having been so dropped from his former or any other organization, obtaining, in the latter case, first, written permission of his former commanding officer. All men taken up after being dropped, shall receive credit for the time served before having been dropped. Men who have been dropped and subsequently taken up shall be reported forthwith by the officer taking them up to the adjutant-general through the regular military channels, and shall be liable to serve an additional period to that already served to complete a full term of enlistment.
