A comprehensive study and comparison of American and German weapons and equipment will be included in Ordnance Overseas, a volume in preparation in the Ordnance subseries of THE UNITED STATES ARMY IN WORLD WAR II. The German infantry division, like the American, had four artillery battalions—three light and one medium. The German pieces were gun-howitzers (105-mm. light, and 150-mm. medium); the American pieces were howitzers (105-mm. and 155-mm.).

23. The name Siegfried Line, or Siegfriedstellung, originated in World War I. It was a German code name given to a rear defensive position established in 1916 behind the central portion of the western front, from the vicinity of Arras to a point just east of Soissons. The position played an important role as the front line fluctuated during the last two years of the war. The Germans fell back on this line in early spring of 1917 and from it launched their last great offensive in March 1918.
