89th Infantry Division (USA)
"Middle West Division"
"Rolling W Division"
The division insignia consists of a black "W" within a circular black tower. The division personnel, during World War I, was drawn primarily from the Middle West, and the "W" indicates its western origin; when inverted, the letter becomes "M" and thus the name, "Middle West" Division.
On its side, the letter represents the Greek letter "sigma", the symbol of summation that is, coordination or single effort. The circle is that geometrical figure which can come to stability in any position, yet move rapidly in answer to a change of forces.
