 The 1st Infantry Division Support Command (DISCOM) traces its origins to World War I, where in 1917, the Division Trains were formed to support the newly formed 1st Infantry Division. In 1921, the Division trains were consolidated into the Special Troops, 1st Infantry Division. After World War I, the Special Troops deployed to Fort Riley, Kansas. Three of the DISCOM's former subordinate battalions, the 101st Forward Support Battalion (FSB) and 201st Forward Support Battalions, and the 701st Main Support Battalion, served in World War I, but with different divisions.
