paragraph_text: In 1956, ArmaLite designed a lightweight assault rifle for military use and designated it the ArmaLite Rifle - 15, or AR - 15.

Buildings had to be cleared room by room through the bombed-out debris of residential neighborhoods, office blocks, basements and apartment high-rises. Some of the taller buildings, blasted into roofless shells by earlier German aerial bombardment, saw floor-by-floor, close quarters combat, with the Germans and Soviets on alternate levels, firing at each other through holes in the floors. Fighting on and around Mamayev Kurgan, a prominent hill above the city, was particularly merciless; indeed, the position changed hands many times.

Following World War II, the French government pursued, in line with its traditional language policy, a campaign to suppress the use of German as part of a wider Francization campaign.
