Here is an excerpt from the Early Mormon Missionaries entry for William Lester Glade:
Early Mormon MissionariesNovember 1915–April 1918Central StatesSet apart by Jos F Smith
When Lester returned from his missionary service he entered the army. I won't repeat all the information about his missionary and military service, since it's been covered before on the blog, but here are some images. First a program for his missionary farewell, then a card showing him while he was in the military. Note the caption, with its reference to his missionary service ("Reverend"). If I recall correctly, he did not make it overseas to fight in the First World War.
