The value of the battleship has been questioned, even during their heyday. There were few of the decisive fleet battles that battleship proponents expected, and used to justify the vast resources spent on building battlefleets. Even in spite of their huge firepower and protection, battleships were increasingly vulnerable to much smaller and relatively inexpensive weapons: initially the torpedo and the naval mine, and later aircraft and the guided missile. The growing range of naval engagements led to the aircraft carrier replacing the battleship as the leading capital ship during World War II, with the last battleship to be launched being HMS Vanguard in 1944. Four battleships were retained by the United States Navy until the end of the Cold War for fire support purposes and were last used in combat during the Gulf War in 1991. The last battleships were stricken from the U.S. Naval Vessel Register in the 2000s. Today, with the exception of Russian Kirov-class battlecruiser, aircraft carriers are the only types of capital ships in service.

does the us navy have any active battleships?

A commander-in-chief is the person or body that exercises supreme operational command and control of a nation's military forces or significant elements of those forces. In the latter case, the force element is those forces within a particular region, or associated by function. As a practical term, it refers to military competencies that reside in a nation-state's executive leadership--either a head of state, a head of government, a minister of defence, a national cabinet, or some other collegial body. Often, a given country's commander-in-chief (if held by an official) need not be or have been a commissioned officer or even a veteran. In these countries this follows the principle of civilian control of the military.

is the president in charge of the military?

A: yes

The nuclear option is a parliamentary procedure that allows the United States Senate to override a rule or precedent by a simple majority of 51 votes, instead of by a supermajority of 60 votes. The option is invoked by the presiding officer of the body ruling that the validity of a Senate rule or precedent is a constitutional question. The issue is immediately put to the full Senate, which decides by majority vote. The procedure thus allows the Senate to decide any issue by majority vote, regardless of existing procedural rules, such as current Senate rules specifying that ending a filibuster requires the consent of 60 senators (out of 100) for legislation, and 67 for amending a Senate rule. The term ''nuclear option'' is an analogy to nuclear weapons being the most extreme option in warfare.

do you need 60 votes in the senate?

A: no

Modern subspecies are descended from elk that once inhabited Beringia, a steppe region between Asia and North America that connected the two continents during the Pleistocene. Beringia provided a migratory route for numerous mammal species, including brown bear, camel, horse, caribou, and moose, as well as humans. As the Pleistocene came to an end, ocean levels began to rise; elk migrated southwards into Asia and North America. In North America they adapted to almost all ecosystems except for tundra, true deserts, and the gulf coast of the U.S. The elk of southern Siberia and central Asia were once more widespread but today are restricted to the mountain ranges west of Lake Baikal including the Sayan and Altai Mountains of Mongolia and the Tianshan region that borders Kyrgyzstan, Kazakhstan, and China's Xinjiang Province. The habitat of Siberian elk in Asia is similar to that of the Rocky Mountain subspecies in North America.

is a caribou the same as an elk?

A:
no
