Seven years prior to the American entry into World War One, the U.S. Army was simply lousy with deserters and it was a problem they were ill equipped to handle:
"For example, take the Sixth Infantry. From that regiment 142 men deserted, or 12 percent of the whole number. Blackest of all records...was that of Company K of the 28th Infantry, located at Fort Snelling, Minnesota. Of the men in this company, nearly one third became disgusted with the service and fared forth to other fields of usefulness."
