of digital images and films are presented on flat screens. Centrepiece of the exhibition is an Austrian M 1916 38 cm siege-howitzer, which could fire shells weighing 750 kg over a distance of 15 km and shell-damaged cupolas from the Antwerp and Przemyśl Forts show the effect of bombardments by such heavy artillery. A replicated emplacement system features a series of display cabinets showing the innovations in weapons technology and equipment as of 1916, including the first Austrian steel-helmet built on the basis of the German model. Another particularly noteworthy exhibit is the Phönix 20.01 training and reconnaissance aircraft, prototype of the Austro-Hungarian produced Albatros B.I(Ph), one of 5,200 planes that the Army and the k.u.k. Navy used in World War I. Moreover, a separate area was dedicated to the k.u.k. Kriegspressequartier (k.u.k. war press bureau) and thus to the arts in war, featuring works by war painters such as Albin Egger-Lienz, Wilhelm Thöny, Oswald Roux, Fritz Schwarz-Waldegg, Stephanie Hollenstein, Anton Faistauer, Ludwig Heinrich Jungnickel, Alexander Pock, and Egon Schiele. Hall VII – Republic and Dictatorship (1918–1955) This Hall is dedicated to the quite turbulent history of the First Republic and World War II. It focuses mainly on the impact of the political events on society and the military, such as, for instance, the July Revolt of 1927 triggered by the Schattendorf judgement and the clashes of February 1934. Exhibits include the weapon used in Schattendorf, and even an M 1918 field howitzer developed in the final stage of World War I and used against the Schutzbund in 1934. The museum only recently obtained those two writings that sculptors Wilhelm Frass and Alfons Riedel had hidden in a shell underneath the monument of the dead soldier in the crypt of Vienna's Heldenplatz. On display are copies of the two documents. Also documented is the history of the Volkswehr and the subsequent Austrian Federal Army; moreover, the assassination of Federal Chancellor Engelbert Dollfuss, Austria's annexation to the Nazi Germany and the resulting integration of the Federal Army in the Wehrmacht in 1938, and the resistance against national socialism in Austria. Apart from infantry/army, navy and air force uniforms of the German Wehrmacht, the exhibition also features uniforms and armour used by the opposing war parties. In addition, a large variety of technical equipment is on display, including: BMW R 12 motorcycle in camouflage painting, NSU Kettenkrad (Sd.Kfz. 2), 8.8-cm anti-aircraft gun,
