What does lost 8 days under AW 107 mean?

Answer 1

This indicates that the soldier on whose discharge papers this appears was found guilty in a minor military justice proceeding of charges under Article of War 107, being AWOL or perhaps overstaying his leave, for eight days. He was probably fined a certain amount - maybe half pay for one to three months - and perhaps confined to the post for a month or two. In normal peacetime the soldier would not get credit for those eight days toward the fulfillment of his enlistment commitment - he would have to stay on eight extra days to make them up. Most WII men were in "for the duration" and were discharged as fast as the Army could get rid of them. These infractions were still noted on discharge papers because if the discharged soldier got a job working for the government as a civilian employee, he again would not get credit for those eight days when calculating his eligibility to retire after twenty or thirty years (but the time he spent actually present for duty DID count toward his thirty years).
