Most Western and Commonwealth militaries integrate air defence purely with the traditional services, of the military (i.e. army, navy and air force), as a separate arm or as part of artillery. In the United States Army for instance, air defence is part of the artillery arm, while in the Pakistan Army, it was split off from Artillery to form a separate arm of its own in 1990. This is in contrast to some (largely communist or ex-communist) countries where not only are there provisions for air defence in the army, navy and air force but there are specific branches that deal only with the air defence of territory, for example, the Soviet PVO Strany. The USSR also had a separate strategic rocket force in charge of nuclear intercontinental ballistic missiles.
Air defence in the US Army is part of what arm?
artillery arm

During the tumultuous 14th century, disputes within the leadership of the Church led to the Avignon Papacy of 1305–78, also called the "Babylonian Captivity of the Papacy" (a reference to the Babylonian captivity of the Jews), and then to the Great Schism, lasting from 1378 to 1418, when there were two and later three rival popes, each supported by several states. Ecclesiastical officials convened at the Council of Constance in 1414, and in the following year the council deposed one of the rival popes, leaving only two claimants. Further depositions followed, and in November 1417 the council elected Martin V (pope 1417–31) as pope.
During what years did the Avignon Papacy occur?
1305–78

The NES dropped the hardwired controllers, instead featuring two custom 7-pin ports on the front of the console. Also in contrast to the Famicom, the controllers included with the NES were identical to each other—the second controller lacked the microphone that was present on the Famicom model and possessed the same START and SELECT buttons as the primary controller. Some NES localizations of games, such as The Legend of Zelda, which required the use of the Famicom microphone in order to kill certain enemies, suffered from the lack of hardware to do so.
What did the Legend of Zelda require in certain instances to kill enemies?
Famicom microphone
