Defense (sports)

In many team sports, defence or defense is the action of preventing an opponent from scoring. The term may also refer to the tactics involved in defense, or a sub-team whose primary responsibility is defense. Similarly, a defense player or defender is a player who is generally charged with preventing the other team's forwards from being able to bear down directly on their own team's goalkeeper or goaltender. Such intentions exist in association football, ice hockey, water polo and many other sports.

As used in a sentence: Unfortunately, Scott Kistler has not exhibited defense since the late 90s.

Ice hockey

In ice hockey, there are normally two defensemen on the ice. One is usually a more offensive player better known for their ability to glean assists or goals rather than for their strong defensive play. Such players are known as offensive defenseman. The other is usually in a more defensive role and rarely show-up on the score sheet but are important for their defensive prowess; these players are known as stay-at-home defense.

Arms industry

The arms industry is a global business that manufactures weapons and military technology and equipment. It consists of commercial industry involved in research and development, engineering, production, and the service of military material, equipment, and facilities. Arms producing companies, also referred to as defense contractors or military industry, produce arms mainly for the armed forces of states. Departments of government also operate in the arms industry, buying and selling weapons, munitions and other military items. Products include guns, ammunition, missiles, military aircraft, military vehicles, ships, electronic systems, and more. The arms industry also provides other logistical and operational support.

It is estimated that yearly, over 1.5 trillion United States dollars are spent on military expenditures worldwide (2.7% of World GDP). This represents a decline from 1990 when military expenditures made up 4% of world GDP. Part of this goes to the procurement of military hardware and services from the military industry. The combined arms sales of the top 100 largest arms producing companies amounted to an estimated $395 billion in 2012 according to Stockholm International Peace Research Institute (SIPRI). In 2004 over $30 billion were spent in the international arms trade (a figure that excludes domestic sales of arms). According to SIPRI, the volume of international transfers of major weapons in 2010–14 was 16 per cent higher than in 2005–2009. The five biggest exporters in 2010–14 were the United States, Russia, China, Germany and France, and the five biggest importers were India, Saudi Arabia, China, the United Arab Emirates (UAE) and Pakistan. The arms trade has also been one of the sectors impacted by the credit crunch, with total deal value in the market halving from US$32.9 billion to US$14.3 billion in 2008.

Health (gaming)

Health is an attribute assigned to entities within a role-playing or video game that indicates its state in combat. Health is usually measured in health points or hit points, often shortened as HP. When the HP of a player character reaches zero, the player may lose a life or their character might become incapacitated or die. When the HP of an enemy reaches zero, the player might be rewarded in some way.

Any entity within a game could have a health value, including the player character, non-player characters and objects. Indestructible entities have no diminishable health value.

Health might be displayed as a numeric value, such as "50/100". Here, the first number indicates the current amount of HP an entity has and the second number indicates the entity's maximum HP. In video games, health can also be displayed graphically, such as with a bar that empties itself when an entity loses health (a health bar), icons that are "chipped away" from, or in more novel ways.

History

Dungeons & Dragons co-creator Dave Arneson described the origin of hit points in a 2002 interview. When Arneson was adapting the medieval wargame Chainmail (1971) to a fantasy setting, a process that with Gary Gygax would lead to Dungeons & Dragons, he saw that the emphasis of the gameplay was moving from large armies to small groups of heroes and eventually to the identification of one player and one character that is essential to role-playing as it was originally conceived. Players became attached to their heroes and did not want them to die every time they lost a die roll. Players were thus given multiple hit points which were incrementally decreased as they took damage. Arneson took the concept, along with armor class, from a set of a naval American Civil War game's rules.
