Input: Read this: A plethora of anti-aircraft gun systems of smaller calibre were available to the German Wehrmacht combined forces, and among them the 1940-origin Flakvierling quadruple-20 mm-gun antiaircraft weapon system was one of the most often-seen weapons, seeing service on both land and sea. The similar Allied smaller-calibre air-defence weapons systems of the American forces were also quite capable, although they receive little attention. Their needs could cogently be met with smaller-calibre ordnance beyond using the usual singly-mounted M2 .50 caliber machine gun atop a tank's turret, as four of the ground-used "heavy barrel" (M2HB) guns were mounted together on the American Maxson firm's M45 Quadmount weapons system (as a direct answer to the Flakvierling),which were often mounted on the back of a half-track to form the Half Track, M16 GMC, Anti-Aircraft. Although of less power than Germany's 20 mm systems, the typical 4 or 5 combat batteries of an Army AAA battalion were often spread many kilometers apart from each other, rapidly attaching and detaching to larger ground combat units to provide welcome defence from enemy aircraft.
Question: What was one of the most often seen weapons that was used both on land and sea?

Output: 1940-origin Flakvierling quadruple-20 mm-gun antiaircraft weapon system

QUES: Industries slowly brought the city and its inhabitants back to a renewed vitality and jobs attracted new residents.

QUES: In addition to the cathedral, Strasbourg houses several other medieval churches that have survived the many wars and destructions that have plagued the city: the Romanesque Eglise Saint-Etienne, partly destroyed in 1944 by Allied bombing raids, the part Romanesque, part Gothic, very large Eglise Saint-Thomas with its Silbermann organ on which Wolfgang Amadeus Mozart and Albert Schweitzer played, the Gothic Eglise protestante Saint-Pierre-le-Jeune with its crypt dating back to the seventh century and its cloister partly from the eleventh century, the Gothic Eglise Saint-Guillaume with its fine early-Renaissance stained glass and furniture, the Gothic Eglise Saint-Jean, the part Gothic, part Art Nouveau Eglise Sainte-Madeleine, etc. The Neo-Gothic church Saint-Pierre-le-Vieux Catholique (there is also an adjacent church Saint-Pierre-le-Vieux Protestant) serves as a shrine for several 15th-century wood worked and painted altars coming from other, now destroyed churches and installed there for public display. Among the numerous secular medieval buildings, the monumental Ancienne Douane (old custom-house) stands out.

Ratification of the treaty the following year led to resumption of hostilities and in 1860, with Anglo-French forces marching on Beijing, the emperor and his court fled the capital for the imperial hunting lodge at Rehe.
