The newspaper Trench and Camp was started for soldiers in training during WWI, with the intention that half the content would be national and identical among each of the 32 editions, with the other half of content being written by local writers.

Trench and Camp did not survive past approximately 1919. What most Americans now think of as the primary publication dealing with the military, Stars and Stripes, began in its modern incarnation during WWI.

However, it had apparently not received enough attention by January 1918 for the New York Times Sunday Magazine to profile it yet — Trench and Camp was still apparently the bigger of the two publications at that point.
