While doing a bit of background research for The Diary of a Stosstrupp Leader, I ran across a depiction of the structure of the 108th Infantry Division on 5 March 1918, While the organogram of the division itself offered no surprises, the diagram that described the units attached to the basic formation revealed something that I had never seen before, an overview of Experimental Artillery Regiment 287 (Versuchs Artillerie Regiment 287).
